Ladies and Gentlemen:
Southern Power Company, a Delaware corporation (the “Company”), confirms its agreement (the “Agreement”) with you and each of the other Underwriters named in Schedule I hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 11 hereof) for whom you are acting as representatives (in such capacity you shall hereinafter be referred to as the “Representatives”), with respect to the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of €600,000,000 aggregate principal amount of the Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Senior Notes”) as set forth in Schedule I hereto.
The Company understands that the Underwriters propose to make a public offering of the Senior Notes as soon as the Representatives deem advisable after this Agreement

The Senior Notes will be issued pursuant to a Senior Note Indenture, dated as of June 1, 2002 (the “Base Indenture”), by and between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as heretofore supplemented and as to be further supplemented by a tenth supplemental indenture, dated as of June 20, 2016, to the Base Indenture relating to the Senior Notes (the “Supplemental Indenture” and, together with the Base Indenture and any other amendments or supplements thereto, the “Indenture”), among the Company, the Trustee and Elavon Financial Services Limited.
In connection with the issuance of the Senior Notes, the Company will enter into a paying agency agreement (the “Paying Agency Agreement”), to be dated as of the Closing Date (as defined below), between the Company and Elavon Financial Services Limited, as London Paying Agent.
The Company is concurrently offering an additional €500,000,000 aggregate principal amount of its Series 2016B 1.850% Senior Notes due June 20, 2026 (the “Series 2016B Senior Notes”), pursuant to a separate underwriting agreement to be entered into by and among the Company and the underwriters named therein.

(b) Payment of the purchase price and delivery of certificates for the Senior Notes shall be made at the offices of Southern Company Services, Inc., 30 Ivan Allen Jr. Blvd., NW, Atlanta, Georgia 30308 at 10:00 A.M., London time, on June 20, 2016 (unless postponed in accordance with the provisions of Section 11 hereof) or such other time, place or date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called the “Closing Date”).

It is understood that each Underwriter has authorized Barclays Bank PLC, for each Underwriter’s account, to accept delivery of, receipt for, and make payment of, the principal amount of the Senior Notes which each Underwriter has agreed to purchase. Barclays Bank PLC,

The certificate(s) for the Senior Notes will be made available for examination by the Representatives not later than 12:00 Noon, London time, on the last business day prior to the Closing Date.
(c) (i) Each Underwriter will not offer, sell, or deliver any of the Senior Notes, directly or indirectly, or distribute the Pricing Prospectus, the Final Supplemented Prospectus or any other offering material relating to the Senior Notes, in or from any jurisdiction except under circumstances that will, to the best of such Underwriter’s knowledge and belief, result in compliance with the applicable laws and regulations and which will not impose any obligations on the Company except as set forth in this Agreement.

(ii) Each Underwriter will sell only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations.
(iii) In relation to each member state of the European Economic Area which has implemented the Prospectus Directive (as defined below) (each, a “Relevant Member State”), with effect from and including the date on which the Prospectus Directive is or was implemented in that Relevant Member State (the “Relevant Implementation Date”), each Underwriter has not made and will not make an offer of the Senior Notes to the public in that Relevant Member State other than: (i) to any legal entity which is a qualified investor as defined in the Prospectus Directive; (ii) to fewer than 150 natural or legal persons (other than qualified investors as defined in the Prospectus Directive), as permitted under the Prospectus Directive, subject to obtaining the prior consent of the Representatives for any such offer; or (iii) in any other circumstances falling within Article 3(2) of the Prospectus Directive; provided, in each case, that no such offer of the Senior Notes shall require the Company or any Underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.
For the purposes of paragraph (iii), the expression “an offer of the Senior Notes to the public” in relation to any of the Senior Notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Senior Notes to be offered so as to enable an investor to decide to purchase or subscribe for any of the Senior Notes, as the same may be varied in that member state by any measure implementing the Prospectus Directive in that member state, and the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive), and includes any relevant implementing measure in the Relevant Member State and the expression “2010 PD Amending Directive” means Directive 2010/73/EU.

        





(iv) Each Underwriter has not sold and will not sell the Senior Notes by means of any document other than (A) in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap. 32, Laws of Hong Kong), (B) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder, or (C) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap. 32, Laws of Hong Kong), and no advertisement, invitation or document relating to the Senior Notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the laws of Hong Kong) other than with respect to Senior Notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.
(v) Each Underwriter will not offer or sell any Senior Notes, directly or indirectly, in Japan or to, or for the benefit of, any Japanese person, or to others for reoffering or resale, directly or indirectly, in Japan or to, or for the benefit of, any Japanese person except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Financial Instruments and Exchange Act of Japan (Law No. 25 of 1948, as amended) and all other applicable laws, regulations and governmental guidelines in effect at the relevant time.

(vi) Each Underwriter will not register the Senior Notes with the Financial Services Commission of Korea for public offering in Korea under the Financial Investment Services and Capital Market Act and its subordinate decrees and regulations (collectively, the “FISCMA”). Each Underwriter represents and agrees that the Senior Notes may not be offered, sold or delivered directly or indirectly, or offered or sold to any person for re-offering or resale, directly or indirectly, in Korea or to any resident of Korea except as otherwise permitted under the applicable laws and regulations of Korea, including the FISCMA and the Foreign Exchange Transaction Law and its subordinate decrees and regulations (collectively, the “FETL”). Without prejudice to the foregoing, the number of the Senior Notes offered in Korea or to a resident in Korea shall be less than 50 and for a period of one year from the issue date of the Senior Notes, none of the Senior Notes may be divided resulting in an increased number of the Senior Notes. Furthermore, the Senior Notes may not be resold to Korean residents unless the purchaser of the Senior Notes complies with all applicable regulatory requirements (including but not limited to government reporting requirements under the FETL) in connection with the purchase of the Senior Notes.

No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

which the United States or European Union is involved, any declaration of war by the United States Congress or European Union or any other substantial national or international calamity, crisis or emergency (including, without limitation, acts of terrorism) affecting the United States or European Union, in any such case provided for in clauses (i) through (iv) with the result that, in the reasonable judgment of the Representatives, the offering, sale or delivery of the Senior Notes on the terms and in the manner contemplated by this Agreement and the Final Supplemented Prospectus shall have been materially impaired.

(b) If this Agreement shall be terminated by the Representatives pursuant to subsection (a) above or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, then in any such case, the Company will reimburse the Underwriters for the reasonable fees and disbursements of Hunton & Williams LLP and for the out of pocket expenses (in an amount not exceeding $10,000) reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Senior Notes and, upon such reimbursement, the Company shall be absolved from any further liability hereunder, except as provided in Sections 5 and 8 hereof.

SECTION 11. DEFAULT BY AN UNDERWRITER .

If an Underwriter shall fail on the Closing Date to purchase the Senior Notes that it is obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:
(a) if the principal amount of Defaulted Securities does not exceed 10% of the Senior Notes, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the principal amount of Defaulted Securities exceeds 10% of the Senior Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.
In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the Pricing Prospectus or the Final Supplemented Prospectus or in any other documents or arrangements.
SECTION 12. NOTICES . All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any





standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives at Barclays Bank PLC, 5 The North Colonnade, Canary Wharf, London E14 4BB, Attention: Debt Syndicate, Fax: +44 (0) 20 7516 7548, BNP Paribas, 10 Harewood Avenue, London NW1 6AA, United Kingdom, Attention: Fixed Income Syndicate, Fax +44 (0) 20 7595 2555, Merrill Lynch International, 2 King Edward Street, London EC1A 1HQ, United Kingdom, Fax: +44 (0) 20 7995 0048, UBS Limited, 1 Finsbury Avenue, London EC2M 2PP, United Kingdom, Fax +44 (0) 20 7567 4146; notices to the Company shall be mailed to 30 Ivan Allen Jr. Boulevard, N.W., Atlanta, Georgia 30308, Attention: Chief Financial Officer, with a copy to Southern Company Services, Inc., 30 Ivan Allen Jr. Boulevard, N.W., Atlanta, Georgia 30308, Attention: Steven Nichols.

SECTION 13. PARTIES . This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Section 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Senior Notes from any of the Underwriters shall be deemed to be a successor by reason merely of such purchase. The Company acknowledges and agrees that in connection with all aspects of each transaction contemplated by this Agreement, the Company and the Underwriters have arms-length business relationships that create no fiduciary duty on the part of any party and each expressly disclaims any fiduciary or financial advisory relationship.

SECTION 14. AGREEMENT AMONG MANAGERS; STABILIZATION . The Underwriters agree as between themselves that they will be bound by and will comply with the International Capital Markets Association Agreement Among Managers Version 1 (Fixed-Price Non Equity-Related Issues)/New York Law Schedule (the “Agreement Among Managers”) as amended in the manner set out as follows: For purposes of the Agreement Among Managers, “Managers” means the Underwriters and the Representatives shall be joint “Lead Managers”, “Settlement Lead Manager” and “Stabilising Manager” means Barclays Bank PLC, and “Subscription Agreement” means this Agreement. Clause 3 of the Agreement Among Managers shall be deleted in its entirety and replaced with Section 11 of this Agreement. In the event of any conflict between the provisions of the Agreement Among Managers and this Agreement, the terms of this Agreement shall prevail.

The Company hereby authorizes Barclays Bank PLC in its role as Stabilising Manager to make adequate public disclosure regarding stabilization of the information required in relation to such stabilization by Commission Regulation (EC) 2273/2003 of the Commission of the European Communities. The Stabilising Manager for its own account may, to the extent permitted by applicable laws and directives, over-allot and effect transactions with a view to supporting the market price of the Senior Notes at a level higher than that which might otherwise prevail, but in doing so the Stabilising Manager shall act as principal and not as agent of the Company and any loss resulting from overallotment and stabilization shall be borne, and any





profit arising therefrom shall be beneficially retained, by the Stabilising Manager. However, there is no assurance that the Stabilising Manager (or persons acting on behalf of the Stabilising Manager) will undertake any stabilization action. Nothing contained in this paragraph shall be construed so as to require the Company to issue in excess of the aggregate principal amount of Senior Notes specified in Schedule I hereto. Such stabilization, if commenced, may be discontinued at any time and shall be conducted by the Stabilising Manager in accordance with all applicable laws and directives.
SECTION 15. JUDGMENT CURRENCY . If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of such Underwriter of any sum in such other currency, and only to the extent that such Underwriter or controlling person of such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person of such Underwriter hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person of such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person of such Underwriter hereunder, such Underwriter or controlling person of such Underwriter agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person of such Underwriter hereunder.

SECTION 16. GOVERNING LAW AND TIME . This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed in said State. Except as otherwise set forth herein, specified times of day refer to London time.

SECTION 17. COUNTERPARTS . This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.
    






If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters and the Company in accordance with its terms.
Very truly yours,

SOUTHERN POWER COMPANY

As Representatives of the Several Underwriters

SOUTHERN POWER COMPANY
Series 2016A 1.000% Senior Notes
due June 20, 2022
Ladies and Gentlemen:
We have acted as counsel to Southern Power Company (the “Company”) in connection with (i) the Company’s issuance of €600,000,000 aggregate principal amount of its Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”) pursuant to a Senior Note Indenture dated as of June 1, 2002, by and between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as heretofore supplemented and as further supplemented by the Tenth Supplemental Indenture dated as of June 20, 2016 (collectively, the “Indenture”); and (ii) the purchase by the Underwriters (as hereinafter defined) of the Notes pursuant to the terms of an Underwriting Agreement dated June 13, 2016, (the “Underwriting Agreement”), among the Company and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”). This opinion is being delivered to you as Representatives pursuant to Section 6(c)(1) of the Underwriting Agreement.

Schedule III-1



All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.
In rendering the opinions expressed below, we have examined the following documents:
(a) The Company’s registration statement on Form S-3 (File No. 333-205680) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”);

(b) The Company’s prospectus dated September 10, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Pricing Exchange Act Documents (as hereinafter defined), the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act;

(c) The documents incorporated by reference into the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus (as hereinafter defined): the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015 and the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 (together, the “Pricing Exchange Act Documents”);

(d) The Company’s prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated June 13, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”);

(e) An executed copy of the Indenture;

(f) An executed copy of the Underwriting Agreement;

(g) The free writing prospectus pertaining to the Notes prepared by the Company and filed with the Commission on June 13, 2016 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”); and

(h) The Company’s charter and bylaws.

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”
In addition, we have examined, and have relied as to factual matters upon, the documents delivered to you at the closing (except the certificate representing the Notes, of which we have examined a specimen), and we have made such other and further investigations as we deemed necessary to express the opinions hereinafter set forth. In such examination, we have

Schedule III-2



assumed (i) the genuineness of all signatures, (ii) the legal capacity of natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.
The Indenture and the Underwriting Agreement are herein referred to collectively as the “Agreements.”
Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that:
1. The Company has been duly organized and is validly existing and in good standing as a corporation under the laws of the State of Delaware and has due corporate authority to carry on the public utility business in which it is engaged, to own and operate the properties used by it in such business and to enter into and perform its obligations under the Agreements and the Notes.

2. The execution, delivery and performance by the Company of the Underwriting Agreement have been duly authorized by all necessary corporate action, and the Underwriting Agreement has been duly executed and delivered by the Company.

3. All orders, consents or other authorizations or approvals of the Federal Energy Regulatory Commission and the Commission legally required for the issuance and the sale of the Notes have been obtained; such orders are sufficient for the issuance and the sale of the Notes; the issuance and the sale of the Notes conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval of the State of Georgia or any United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no opinion) is legally required for the issuance and the sale of the Notes in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, subject to the qualifications that the enforceability of the Company’s obligations under the Indenture may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by

Schedule III-3



general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

6. Each of the Indenture and the Notes conforms as to legal matters in all material respects to the descriptions thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

7. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

8.      The execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Notes, and the consummation of the transactions contemplated thereby, do not result in any violation of (i) the charter or bylaws of the Company or (ii) any existing applicable law, rule, or regulation of the State of New York.
9.      The statements set forth in the Pricing Disclosure Package and the Final Supplemented Prospectus under the heading “United States Federal Income Tax Considerations” insofar as they purport to constitute summaries of matters of United States federal income tax law constitute accurate summaries in all material respects subject to the qualifications set forth therein.
The attorneys in this firm that are rendering this opinion are members of the State Bar of Georgia and we do not purport to express any opinion herein concerning any law other than the laws of the State of Georgia, the federal law of the United States, the Delaware General Corporation Law and, to the extent set forth herein, the laws of the State of New York. As to all matters governed by or dependent upon the laws of the State of New York, we have, with your consent, relied upon the opinion of Hunton & Williams LLP dated the date hereof and addressed to you.
This opinion letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent, except that copies of this opinion letter may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body. This opinion is expressed as of the date hereof, and we do not assume any obligation to update or supplement it to reflect any fact or circumstance that hereafter comes to our attention, or any change in law that hereafter occurs.
Yours very truly,
TROUTMAN SANDERS LLP

SOUTHERN POWER COMPANY
Series 2016A 1.000% Senior Notes
due June 20, 2022
Ladies and Gentlemen:
We have acted as counsel to Southern Power Company (the “Company”) in connection with (i) the Company’s issuance of €600,000,000 aggregate principal amount of its Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”) pursuant to a Senior Note Indenture dated as of June 1, 2002, by and between the Company and Wells Fargo Bank, National Association, as trustee, as heretofore supplemented and as further supplemented by the Tenth Supplemental Indenture dated as of June 20, 2016; and (ii) the purchase by the Underwriters (as hereinafter defined) of the Notes pursuant to the terms of an Underwriting Agreement dated June 13, 2016 (the “Underwriting Agreement”), among the Company and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”). This letter is being delivered to you as Representatives pursuant to Section 6(c)(1) of the Underwriting Agreement.

Schedule III-5



All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.
In the above capacity, we have examined the Company’s registration statement on Form S-3 (File No. 333-205680) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated September 10, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement pertaining to the Notes dated June 13, 2016 (the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act which, pursuant to Form S-3, incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015 and the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 (together, the “Pricing Exchange Act Documents”), and a prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated June 13, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We have also examined the free writing prospectus pertaining to the Notes prepared by the Company and filed with the Commission on June 13, 2016 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”). The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”
We have participated in various conferences with the Company, its representatives, representatives of the independent public or certified public accountants of the Company and your counsel at which the contents of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and related matters were discussed and reviewed. Because of the inherent limitations in the independent verification of factual matters, and the character of the determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we are not passing upon and do not assume any responsibility for, and make no representation that we have independently verified, the accuracy, completeness or fairness of the statements contained therein (other than as specified in opinion paragraph 6 of our opinion to you related to the Indenture and the Notes dated of even date herewith). However, on the basis of the foregoing, we advise you that nothing has come to our attention which has caused us to believe that:
(i) the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading,

(ii) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make

Schedule III-6



the statements therein, in light of the circumstances under which they were made, not misleading, or

(iii) the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,

except that in each case we express no belief with respect to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the caption “Description of the Series 2016A Senior Notes ─ Book-Entry Procedures.”
Subject to and on the basis of the foregoing, we further advise you that the Registration Statement, on the Effective Date, and the Final Supplemented Prospectus, as of June 13, 2016, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that each Exchange Act Document, as of its date of filing with the Commission, complied as to form in all material respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no belief as to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents.
This letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent, except that copies of this letter may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body. This letter is expressed as of the date hereof, and we do not assume any obligation to update or supplement it to reflect any fact or circumstance that hereafter comes to our attention or any change in law that hereafter occurs.

SOUTHERN POWER COMPANY
Series 2016A 1.000% Senior Notes due June 20, 2022
Ladies and Gentlemen:
We have acted as counsel for Wells Fargo Bank, National Association (“Wells Fargo”) in connection with the issuance by Southern Power Company (the “Company”) of €600,000,000 aggregate principal amount of Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”). The Notes are being issued under the Senior Note Indenture dated as of June 1, 2002 (the “Original Indenture”) between the Company and Wells Fargo, as trustee (in such capacity, the “Trustee”), as heretofore supplemented and as further supplemented by the Tenth Supplemental Indenture dated as of June 20, 2016 (the “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”) between the Company and the Trustee.

Schedule IV-1



For purposes of this opinion, we have reviewed the Indenture and such other documents, records and papers, and satisfied ourselves as to such other matters, as we have deemed necessary or appropriate for this opinion. As to questions of fact material to this opinion, we have relied on certificates of Wells Fargo and of public officials. In such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies or forms and the authenticity of the originals of such latter documents. We have assumed that Wells Fargo has been duly formed and that the Indenture has been duly authorized, executed and delivered by the Company and constitutes the valid and binding agreement of, and is enforceable in accordance with its terms against, the Company.
Based upon the foregoing and subject to the qualifications below, we are of the opinion that:
1)      Based solely on a certificate from the Comptroller of the Currency, Wells Fargo is a national banking association formed under the laws of the United States and is authorized thereunder to transact the business of banking and exercise fiduciary powers.

2)      The Supplemental Indenture has been duly authorized, executed and delivered by Wells Fargo and the Indenture constitutes a valid and binding agreement of Wells Fargo enforceable against Wells Fargo in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and by an implied covenant of reasonableness, good faith and fair dealing.

We are members of the Bar of the State of New York and, for purposes of this opinion, do not hold ourselves out as experts on the laws of any jurisdiction other than the State of New York and the federal law of the United States. The opinions expressed herein are limited to matters governed by the laws of the State of New York and the federal law of the United States.
This opinion is solely for your benefit in connection with the issuance and sale by the Company of the Notes and may not be relied upon by you for any other purpose, or relied upon or furnished to any other person, without our prior written consent, except that copies of this opinion may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body.
Very truly yours,

This opinion is being delivered to you as Representatives pursuant to Section 6(c)(3) of the Underwriting Agreement.

Schedule V-1



All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.
In rendering the opinions expressed below, we have examined the following documents:
(a) The Company’s registration statement on Form S-3 (File No. 333-205680) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”);

(b) The Company’s prospectus dated September 10, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Pricing Exchange Act Documents (as hereinafter defined), the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act;

(c) The documents incorporated by reference into the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus (as hereinafter defined): the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015 and the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 (together, the “Pricing Exchange Act Documents”);

(d) The Company’s prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated June 13, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”);

(e) An executed copy of the Indenture;

(f) An executed copy of the Underwriting Agreement;

(g) The free writing prospectus pertaining to the Notes prepared by the Company and filed with the Commission on June 13, 2016 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”); and

(h) The Company’s charter and bylaws.

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”
In addition, we have examined, and have relied as to factual matters upon, the documents delivered to you at the closing (except the certificate representing the Notes, of which we have examined a specimen), and we have made such other and further investigations as we deemed necessary to express the opinions hereinafter set forth. In such examination, we have

Schedule V-2



assumed (i) the genuineness of all signatures, (ii) the legal capacity of natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.
The Indenture and the Underwriting Agreement are herein referred to collectively as the “Agreements.”
Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that:
1. The Company has been duly organized and is validly existing and in good standing as a corporation under the laws of the State of Delaware and has due corporate authority to carry on the public utility business in which it is engaged, to own and operate the properties used by it in such business and to enter into and perform its obligations under the Agreements and the Notes.

2. The execution, delivery and performance by the Company of the Underwriting Agreement have been duly authorized by all necessary corporate action, and the Underwriting Agreement has been duly executed and delivered by the Company.

3. All orders, consents or other authorizations or approvals of the Federal Energy Regulatory Commission and the Commission legally required for the issuance and the sale of the Notes have been obtained; such orders are sufficient for the issuance and the sale of the Notes; the issuance and the sale of the Notes conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval of the State of New York or any United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no opinion) is legally required for the issuance and the sale of the Notes in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, subject to the qualifications that the enforceability of the Company’s obligations under the Indenture may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by

Schedule V-3



general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

6. Each of the Indenture and the Notes conforms as to legal matters in all material respects to the descriptions thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

7. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

8.      The execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Notes, and the consummation of the transactions contemplated thereby, do not result in any violation of (i) the charter or bylaws of the Company or (ii) any existing applicable law, rule, or regulation of the State of New York.
We do not purport to express any opinion herein concerning any law other than the laws of the State of New York and the federal law of the United States and the Delaware General Corporation Law.
This opinion letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent except that Troutman Sanders LLP may rely on this opinion in giving its opinions pursuant to Section 6 of the Underwriting Agreement and pursuant to Sections 102, 302 and 904 of the Indenture, insofar as such opinions relate to matters of New York law and except that copies of this opinion letter may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body. This opinion is expressed as of the date hereof, and we do not assume any obligation to update or supplement it to reflect any fact or circumstance that hereafter comes to our attention, or any change in law that hereafter occurs.

We have represented the Underwriters (as hereinafter defined) in connection with (i) the issuance and sale by Southern Power Company (the “Company”) of €600,000,000 aggregate principal amount of its Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”) pursuant to a Senior Note Indenture, dated as of June 1, 2002, by and between the Company and Wells Fargo Bank, National Association, as trustee, as heretofore supplemented and as further supplemented by the Tenth Supplemental Indenture, dated as of June 20, 2016; and (ii) the purchase by the Underwriters of the Notes pursuant to the terms of an Underwriting Agreement, dated June 13, 2016 (the “Underwriting Agreement”), among the Company and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”). This letter is being delivered to you as Representatives pursuant to Section 6(c)(3) of the Underwriting Agreement.
All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.

Schedule V-5



In the above capacity, we have examined the Company’s registration statement on Form S-3 (File No. 333-205680) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated September 10, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement pertaining to the Notes dated June 13, 2016 (the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act which, pursuant to Form S-3, incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015 and the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 (together, the “Pricing Exchange Act Documents”), and a prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated June 13, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We have also examined the free writing prospectus pertaining to the Notes prepared by the Company and filed with the Commission on June 13, 2016, pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”). The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”
We have participated in various conferences with the Company, its counsel, its representatives and representatives of the independent public or certified public accountants of the Company at which the contents of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and related matters were discussed and reviewed. Because of the inherent limitations in the independent verification of factual matters, and the character of the determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we are not passing upon and do not assume any responsibility for, and make no representation that we have independently verified, the accuracy, completeness or fairness of the statements contained therein (other than as specified in opinion paragraph 6 of our opinion to you related to the Indenture and the Notes dated of even date herewith). However, on the basis of the foregoing, we advise you that nothing has come to our attention which has caused us to believe that:
(i) the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading,

(ii) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or


Schedule V-6



(iii) the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,

except that in each case we express no belief with respect to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the caption “Description of the Series 2016A Senior Notes ─ Book-Entry Procedures.”
Subject to and on the basis of the foregoing, we further advise you that the Registration Statement, on the Effective Date, and the Final Supplemented Prospectus, as of June 13, 2016, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that each Exchange Act Document, as of its date of filing with the Commission, complied as to form in all material respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no belief as to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents.
This letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent, except that copies of this letter may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body.

(e) The Representatives shall have received on the date hereof and shall receive on the Closing Date from Deloitte & Touche LLP, a letter or letters addressed to the Representatives (which may refer to letters previously delivered to the Representatives) dated the respective dates of delivery thereof to the effect that: (A) they are an independent registered public accounting firm with respect to the Company within the meaning of the 1933 Act and the rules and regulations under the 1933 Act; (B) in their opinion, the financial statements audited by them and incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, comply as to form in all material respects with the applicable accounting requirements of the 1934 Act and the rules and regulations under the 1934 Act; and (C) on the basis of certain limited procedures performed through a specified date not more than three business days prior to the date of such letter, namely (i) reading the minute books of the Company; (ii) performing the procedures specified by the standards of the Public Company Accounting Oversight Board (United States) for a review of interim financial statement information as described in PCAOB AU 722, “Interim Financial Information” on the unaudited financial statements, if any, of the Company incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, and on the latest available unaudited financial statements of the Company, if any, for any calendar quarter subsequent to the date of those incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable; and (iii) making inquiries of certain officials of the Company who have responsibility for financial and accounting matters regarding such unaudited financial statements or any specified unaudited amounts derived therefrom (it being understood that the foregoing procedures do not constitute an audit performed in accordance with generally accepted auditing standards and they would not necessarily reveal matters of significance with respect to the comments made in such letter, and accordingly that Deloitte & Touche LLP make no representations as to the sufficiency of such procedures for the Underwriters’ purposes), nothing came to their attention that caused them to believe that: (1) any material modifications should be made to the unaudited condensed financial statements, if any, incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable for them to be in conformity with GAAP; (2) such unaudited condensed financial statements do not comply as to form in all material respects with the applicable accounting requirements of the 1934 Act as it applies to Form 10-Q and the related published rules and regulations thereunder; (3) the audited or unaudited amounts for Operating Revenues, Earnings Before Income Taxes and Net Income and the audited or unaudited Ratio of Earnings to Fixed Charges set forth in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, do not agree with the amounts set forth in or derived from the audited or unaudited financial statements for the same period included or incorporated by reference in the Registration Statement; (4) as of a specified date not more than three business days prior to the date of delivery of such letter, there has been any change in the capital stock or long-term debt of the Company or any decrease in net assets as compared with amounts shown in the latest audited or unaudited balance sheet incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, except in each case for





changes or decreases which (i) the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, disclose, have occurred or may occur, (ii) are occasioned by the declaration of dividends, (iii) are occasioned by draw-downs and regularly scheduled payments of capitalized lease obligations, (iv) are occasioned by the purchase or redemption of bonds or stock to satisfy mandatory or optional redemption provisions relating thereto, (v) are occasioned by the reclassification of current maturities of long-term debt, or (vi) are disclosed in such letter; and (5) the unaudited amounts for Operating Revenues, Earnings Before Income Taxes and Net Income and the unaudited Ratio of Earnings to Fixed Charges for any calendar quarter subsequent to those set forth in (3) above, which, if available, shall be set forth in such letter, do not agree with the amounts set forth in or derived from the unaudited financial statements for the same period or were not determined on a basis substantially consistent with that of the corresponding audited amounts or ratios included or incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable.

(f) On the Closing Date, Hunton & Williams LLP, counsel for the Underwriters, shall have been furnished with such documents and opinions as it may reasonably require for the purpose of enabling it to pass upon the issuance and sale of the Senior Notes as herein contemplated and related proceedings, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Senior Notes as herein contemplated shall be satisfactory in form and substance to the Representatives and Hunton & Williams LLP, counsel for the Underwriters.

(g) No amendment or supplement to the Registration Statement or the Final Supplemented Prospectus filed subsequent to the date of this Agreement (including any filing made by the Company pursuant to Section 13 or 14 of the 1934 Act) shall be unsatisfactory in form to Hunton & Williams LLP or shall contain information (other than with respect to an amendment or supplement relating solely to the activity of any Underwriter) which, in the reasonable judgment of the Representatives, shall materially impair the marketability of the Senior Notes.

(h) The Company shall have performed its obligations when and as provided under this Agreement.

(i) The Representatives shall have received an executed copy of the Paying Agency Agreement.

(j) On the Closing Date, the Senior Notes shall have been approved for listing on the NYSE upon official notice of issuance.

(k) On the Closing Date, the Senior Notes shall be eligible for clearance and settlement through Clearstream and Euroclear.

If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to





the Company at any time prior to the Closing Date, and such termination shall be without liability of any party to any other party except as provided in Sections 5, 8 and 10(b) hereof.
SECTION 7. CONDITIONS OF THE OBLIGATIONS OF THE COMPANY .

The obligations of the Company shall be subject to the conditions set forth in the first sentence of Section 6(a) and in Section 6(b) hereof. In case such conditions shall not have been fulfilled, this Agreement may be terminated by the Company by mailing or delivering written notice thereof to the Representatives. Any such termination shall be without liability of any party to any other party except as otherwise provided in Sections 5, 8 and 10(b) hereof.
SECTION 8. INDEMNIFICATION .

(a) The Company agrees to indemnify and hold harmless each of the Underwriters and each person, if any, who controls any such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the 1933 Act, the 1934 Act or otherwise, and to reimburse any such Underwriter and such controlling person or persons, if any, for any legal or other expenses incurred by them in connection with defending any actions, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Limited Use Free Writing Prospectus, any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus or, if the Company shall furnish to the Underwriters any amendments or any supplements thereto, or shall make any filings pursuant to Section 13 or 14 of the 1934 Act which are incorporated therein by reference, in a Limited Use Free Writing Prospectus, any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus, the Final Supplemented Prospectus as so amended or supplemented, or in any free writing prospectus used by the Company other than a Permitted Free Writing Prospectus or a Limited Use Free Writing Prospectus, or arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any such untrue statement or alleged untrue statement or omission or alleged omission which was made in such Limited Use Free Writing Prospectus, Preliminary Prospectus, Registration Statement, Base Prospectus, Pricing Prospectus, Permitted Free Writing Prospectus or Final Supplemented Prospectus in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives for use therein. Each Underwriter agrees, within ten days after the receipt by it of notice of the commencement of any action in respect of which indemnity may be sought by it, or by any person controlling it, from the Company on account of its agreement contained in this Section 8, to notify the Company in writing of the commencement thereof but the omission of such Underwriter so to notify the Company of any such action shall not release the Company from any liability which it may have to such Underwriter or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 8. In case any such action shall be brought against an Underwriter or any such person controlling such Underwriter and such Underwriter shall notify the Company of the commencement thereof as above provided, the Company shall be entitled to





participate in (and, to the extent that it shall wish, including the selection of counsel, to direct) the defense thereof, at its own expense. In case the Company elects to direct such defense and select such counsel, any Underwriter or controlling person shall have the right to employ its own counsel, but, in any such case, the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless the employment of such counsel has been authorized in writing by the Company in connection with defending such action. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors and such of its officers who have signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act to the same extent and upon the same terms as the indemnity agreement of the Company set forth in Section 8(a) hereof, but only with respect to alleged untrue statements or omissions made in a Limited Use Free Writing Prospectus, the Registration Statement, the Preliminary Prospectus, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus, or such documents as amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives for use therein.

SECTION 9. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY .

All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by, or on behalf of the Company and shall survive delivery of the Senior Notes to the Underwriters.
SECTION 10. TERMINATION OF AGREEMENT .

(a) The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Date if (i) trading in securities on the NYSE shall have been generally suspended or there shall have been a material disruption in settlement in securities generally, (ii) minimum or maximum ranges for prices shall have been generally established on the NYSE by the Commission or by the NYSE, (iii) a general banking moratorium shall have been declared by federal or New York State or European Union authorities, or (iv) there shall have occurred any outbreak or escalation of major hostilities in





which the United States or European Union is involved, any declaration of war by the United States Congress or European Union or any other substantial national or international calamity, crisis or emergency (including, without limitation, acts of terrorism) affecting the United States or European Union, in any such case provided for in clauses (i) through (iv) with the result that, in the reasonable judgment of the Representatives, the offering, sale or delivery of the Senior Notes on the terms and in the manner contemplated by this Agreement and the Final Supplemented Prospectus shall have been materially impaired.

(b) If this Agreement shall be terminated by the Representatives pursuant to subsection (a) above or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, then in any such case, the Company will reimburse the Underwriters for the reasonable fees and disbursements of Hunton & Williams LLP and for the out of pocket expenses (in an amount not exceeding $10,000) reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Senior Notes and, upon such reimbursement, the Company shall be absolved from any further liability hereunder, except as provided in Sections 5 and 8 hereof.

SECTION 11. DEFAULT BY AN UNDERWRITER .

If an Underwriter shall fail on the Closing Date to purchase the Senior Notes that it is obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:
(a) if the principal amount of Defaulted Securities does not exceed 10% of the Senior Notes, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the principal amount of Defaulted Securities exceeds 10% of the Senior Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.
In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the Pricing Prospectus or the Final Supplemented Prospectus or in any other documents or arrangements.
SECTION 12. NOTICES . All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any





standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives at Barclays Bank PLC, 5 The North Colonnade, Canary Wharf, London E14 4BB, Attention: Debt Syndicate, Fax: +44 (0) 20 7516 7548, BNP Paribas, 10 Harewood Avenue, London NW1 6AA, United Kingdom, Attention: Fixed Income Syndicate, Fax +44 (0) 20 7595 2555, Merrill Lynch International, 2 King Edward Street, London EC1A 1HQ, United Kingdom, Fax: +44 (0) 20 7995 0048, UBS Limited, 1 Finsbury Avenue, London EC2M 2PP, United Kingdom, Fax +44 (0) 20 7567 4146; notices to the Company shall be mailed to 30 Ivan Allen Jr. Boulevard, N.W., Atlanta, Georgia 30308, Attention: Chief Financial Officer, with a copy to Southern Company Services, Inc., 30 Ivan Allen Jr. Boulevard, N.W., Atlanta, Georgia 30308, Attention: Steven Nichols.

SECTION 13. PARTIES . This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Section 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Senior Notes from any of the Underwriters shall be deemed to be a successor by reason merely of such purchase. The Company acknowledges and agrees that in connection with all aspects of each transaction contemplated by this Agreement, the Company and the Underwriters have arms-length business relationships that create no fiduciary duty on the part of any party and each expressly disclaims any fiduciary or financial advisory relationship.

SECTION 14. AGREEMENT AMONG MANAGERS; STABILIZATION . The Underwriters agree as between themselves that they will be bound by and will comply with the International Capital Markets Association Agreement Among Managers Version 1 (Fixed-Price Non Equity-Related Issues)/New York Law Schedule (the “Agreement Among Managers”) as amended in the manner set out as follows: For purposes of the Agreement Among Managers, “Managers” means the Underwriters and the Representatives shall be joint “Lead Managers”, “Settlement Lead Manager” and “Stabilising Manager” means Barclays Bank PLC, and “Subscription Agreement” means this Agreement. Clause 3 of the Agreement Among Managers shall be deleted in its entirety and replaced with Section 11 of this Agreement. In the event of any conflict between the provisions of the Agreement Among Managers and this Agreement, the terms of this Agreement shall prevail.

The Company hereby authorizes Barclays Bank PLC in its role as Stabilising Manager to make adequate public disclosure regarding stabilization of the information required in relation to such stabilization by Commission Regulation (EC) 2273/2003 of the Commission of the European Communities. The Stabilising Manager for its own account may, to the extent permitted by applicable laws and directives, over-allot and effect transactions with a view to supporting the market price of the Senior Notes at a level higher than that which might otherwise prevail, but in doing so the Stabilising Manager shall act as principal and not as agent of the Company and any loss resulting from overallotment and stabilization shall be borne, and any





profit arising therefrom shall be beneficially retained, by the Stabilising Manager. However, there is no assurance that the Stabilising Manager (or persons acting on behalf of the Stabilising Manager) will undertake any stabilization action. Nothing contained in this paragraph shall be construed so as to require the Company to issue in excess of the aggregate principal amount of Senior Notes specified in Schedule I hereto. Such stabilization, if commenced, may be discontinued at any time and shall be conducted by the Stabilising Manager in accordance with all applicable laws and directives.
SECTION 15. JUDGMENT CURRENCY . If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of such Underwriter of any sum in such other currency, and only to the extent that such Underwriter or controlling person of such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person of such Underwriter hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person of such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person of such Underwriter hereunder, such Underwriter or controlling person of such Underwriter agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person of such Underwriter hereunder.

SECTION 16. GOVERNING LAW AND TIME . This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed in said State. Except as otherwise set forth herein, specified times of day refer to London time.

SECTION 17. COUNTERPARTS . This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.








If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters and the Company in accordance with its terms.
Very truly yours,

SOUTHERN POWER COMPANY

As Representatives of the Several Underwriters

SOUTHERN POWER COMPANY
Series 2016B 1.850% Senior Notes
due June 20, 2026
Ladies and Gentlemen:
We have acted as counsel to Southern Power Company (the “Company”) in connection with (i) the Company’s issuance of €500,000,000 aggregate principal amount of its Series 2016B 1.850% Senior Notes due June 20, 2026 (the “Notes”) pursuant to a Senior Note Indenture dated as of June 1, 2002, by and between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as heretofore supplemented and as further supplemented by the Eleventh Supplemental Indenture dated as of June 20, 2016 (collectively, the “Indenture”); and (ii) the purchase by the Underwriters (as hereinafter defined) of the Notes pursuant to the terms of an Underwriting Agreement dated June 13, 2016, (the “Underwriting Agreement”), among the Company and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”). This opinion is being delivered to you as Representatives pursuant to Section 6(c)(1) of the Underwriting Agreement.

Schedule III-1



All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.
In rendering the opinions expressed below, we have examined the following documents:
(a) The Company’s registration statement on Form S-3 (File No. 333-205680) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”);

(b) The Company’s prospectus dated September 10, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Pricing Exchange Act Documents (as hereinafter defined), the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act;

(c) The documents incorporated by reference into the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus (as hereinafter defined): the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015 and the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 (together, the “Pricing Exchange Act Documents”);

(d) The Company’s prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated June 13, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”);

(e) An executed copy of the Indenture;

(f) An executed copy of the Underwriting Agreement;

(g) The free writing prospectus pertaining to the Notes prepared by the Company and filed with the Commission on June 13, 2016 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”); and

(h) The Company’s charter and bylaws.

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”
In addition, we have examined, and have relied as to factual matters upon, the documents delivered to you at the closing (except the certificate representing the Notes, of which we have examined a specimen), and we have made such other and further investigations as we deemed necessary to express the opinions hereinafter set forth. In such examination, we have

Schedule III-2



assumed (i) the genuineness of all signatures, (ii) the legal capacity of natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.
The Indenture and the Underwriting Agreement are herein referred to collectively as the “Agreements.”
Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that:
1. The Company has been duly organized and is validly existing and in good standing as a corporation under the laws of the State of Delaware and has due corporate authority to carry on the public utility business in which it is engaged, to own and operate the properties used by it in such business and to enter into and perform its obligations under the Agreements and the Notes.

2. The execution, delivery and performance by the Company of the Underwriting Agreement have been duly authorized by all necessary corporate action, and the Underwriting Agreement has been duly executed and delivered by the Company.

3. All orders, consents or other authorizations or approvals of the Federal Energy Regulatory Commission and the Commission legally required for the issuance and the sale of the Notes have been obtained; such orders are sufficient for the issuance and the sale of the Notes; the issuance and the sale of the Notes conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval of the State of Georgia or any United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no opinion) is legally required for the issuance and the sale of the Notes in accordance with the terms of the Underwriting Agreement.

4.

Ladies and Gentlemen:
We have acted as counsel to Southern Power Company (the “Company”) in connection with (i) the Company’s issuance of €500,000,000 aggregate principal amount of its Series 2016B 1.850% Senior Notes due June 20, 2026 (the “Notes”) pursuant to a Senior Note Indenture dated as of June 1, 2002, by and between the Company and Wells Fargo Bank, National Association, as trustee, as heretofore supplemented and as further supplemented by the Eleventh Supplemental Indenture dated as of June 20, 2016; and (ii) the purchase by the Underwriters (as hereinafter defined) of the Notes pursuant to the terms of an Underwriting Agreement dated June 13, 2016 (the “Underwriting Agreement”), among the Company and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”). This letter is being delivered to you as Representatives pursuant to Section 6(c)(1) of the Underwriting Agreement.

Schedule III-5



All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.
In the above capacity, we have examined the Company’s registration statement on Form S-3 (File No. 333-205680) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated September 10, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement pertaining to the Notes dated June 13, 2016 (the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act which, pursuant to Form S-3, incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015 and the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 (together, the “Pricing Exchange Act Documents”), and a prospectus supplement pertaining to the Notes dated June 13, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated June 13, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We have also examined the free writing prospectus pertaining to the Notes prepared by the Company and filed with the Commission on June 13, 2016 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”). The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”
We have participated in various conferences with the Company, its representatives, representatives of the independent public or certified public accountants of the Company and your counsel at which the contents of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and related matters were discussed and reviewed. Because of the inherent limitations in the independent verification of factual matters, and the character of the determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we are not passing upon and do not assume any responsibility for, and make no representation that we have independently verified, the accuracy, completeness or fairness of the statements contained therein (other than as specified in opinion paragraph 6 of our opinion to you related to the Indenture and the Notes dated of even date herewith). However, on the basis of the foregoing, we advise you that nothing has come to our attention which has caused us to believe that:
(i) the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading,

(ii) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make

Schedule III-6



the statements therein, in light of the circumstances under which they were made, not misleading, or

(iii) the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,

except that in each case we express no belief with respect to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the caption “Description of the Series 2016B Senior Notes ─ Book-Entry Procedures.”
Subject to and on the basis of the foregoing, we further advise you that the Registration Statement, on the Effective Date, and the Final Supplemented Prospectus, as of June 13, 2016, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that each Exchange Act Document, as of its date of filing with the Commission, complied as to form in all material respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no belief as to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents.
This letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent, except that copies of this letter may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body.

SOUTHERN POWER COMPANY
Series 2016B 1.850% Senior Notes due June 20, 2026
Ladies and Gentlemen:
We have acted as counsel for Wells Fargo Bank, National Association (“Wells Fargo”) in connection with the issuance by Southern Power Company (the “Company”) of €500,000,000 aggregate principal amount of Series 2016B 1.850% Senior Notes due June 20, 2026 (the “Notes”). The Notes are being issued under the Senior Note Indenture dated as of June 1, 2002 (the “Original Indenture”) between the Company and Wells Fargo, as trustee (in such capacity, the “Trustee”), as heretofore supplemented and as further supplemented by the Eleventh Supplemental Indenture dated as of June 20, 2016 (the “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”) between the Company and the Trustee.

Schedule IV-1



For purposes of this opinion, we have reviewed the Indenture and such other documents, records and papers, and satisfied ourselves as to such other matters, as we have deemed necessary or appropriate for this opinion. As to questions of fact material to this opinion, we have relied on certificates of Wells Fargo and of public officials. In such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies or forms and the authenticity of the originals of such latter documents. We have assumed that Wells Fargo has been duly formed and that the Indenture has been duly authorized, executed and delivered by the Company and constitutes the valid and binding agreement of, and is enforceable in accordance with its terms against, the Company.
Based upon the foregoing and subject to the qualifications below, we are of the opinion that:
1)      Based solely on a certificate from the Comptroller of the Currency, Wells Fargo is a national banking association formed under the laws of the United States and is authorized thereunder to transact the business of banking and exercise fiduciary powers.

2)      The Supplemental Indenture has been duly authorized, executed and delivered by Wells Fargo and the Indenture constitutes a valid and binding agreement of Wells Fargo enforceable against Wells Fargo in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and by an implied covenant of reasonableness, good faith and fair dealing.

We are members of the Bar of the State of New York and, for purposes of this opinion, do not hold ourselves out as experts on the laws of any jurisdiction other than the State of New York and the federal law of the United States. The opinions expressed herein are limited to matters governed by the laws of the State of New York and the federal law of the United States.
This opinion is solely for your benefit in connection with the issuance and sale by the Company of the Notes and may not be relied upon by you for any other purpose, or relied upon or furnished to any other person, without our prior written consent, except that copies of this opinion may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body.

3. All orders, consents or other authorizations or approvals of the Federal Energy Regulatory Commission and the Commission legally required for the issuance and the sale of the Notes have been obtained; such orders are sufficient for the issuance and the sale of the Notes; the issuance and the sale of the Notes conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval of the State of New York or any United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no opinion) is legally required for the issuance and the sale of the Notes in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, subject to the qualifications that the enforceability of the Company’s obligations under the Indenture may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by

Schedule V-3



general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

6. Each of the Indenture and the Notes conforms as to legal matters in all material respects to the descriptions thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

7. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

8.      The execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Notes, and the consummation of the transactions contemplated thereby, do not result in any violation of (i) the charter or bylaws of the Company or (ii) any existing applicable law, rule, or regulation of the State of New York.
We do not purport to express any opinion herein concerning any law other than the laws of the State of New York and the federal law of the United States and the Delaware General Corporation Law.
This opinion letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent except that Troutman Sanders LLP may rely on this opinion in giving its opinions pursuant to Section 6 of the Underwriting Agreement and pursuant to Sections 102, 302 and 904 of the Indenture, insofar as such opinions relate to matters of New York law and except that copies of this opinion letter may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body.

Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the Series 2016A Notes are registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of the Series 2016A Notes not less than ten (10) days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Series 2016A Notes shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Original Indenture.

If the Stated Maturity or any Redemption Date of the Series 2016A Notes falls on a day that is not a Business Day, the related payment of principal, premium, if any, and interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest shall accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.
All payments of interest and principal, including payments made upon any redemption of the Series 2016A Notes, will be payable in euro. If, on or after the Original Issue Date, the Company is unable to obtain euro in amounts sufficient to make a required payment under the Series 2016A Notes due to the imposition of exchange controls or other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Series 2016A Notes will be made in U.S. dollars until the euro is again available to the Company or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. dollar/euro exchange rate available on or prior to the second Business Day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment in respect of the Series 2016A Notes so made in U.S. dollars will not constitute an Event of Default under the Series 2016A Notes or the Indenture. Neither the Trustee nor the Paying Agent shall have any responsibility for any calculation or conversion in connection with the foregoing.
Principal of, premium, if any, and interest on the Series 2016A Notes will be payable at the office of the Paying Agent or, at the Company’s option, payment of interest may be made by check

The Global Securities described above may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee.
Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a Series 2016A Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee. The rights of Holders of such Global Security shall be exercised only through the Depositary.
Subject to the procedures of the Depositary, a Global Security shall be exchangeable for Series 2016A Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Company, or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Company, in each case within 90 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the Series 2016A Notes.

If the Stated Maturity or any Redemption Date of the Series 2016A Notes falls on a day that is not a Business Day, the related payment of principal, premium, if any, and interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest shall accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day. A “Business Day” shall mean any day, other than a Saturday or Sunday, (i) which is not a day on which banks in The City of New York or London are authorized or obligated by law or executive order to close and (ii) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.
All payments of interest and principal, including payments made upon any redemption of the Series 2016A Notes, will be payable in euro. If, on or after the Original Issue Date, the Company is unable to obtain euro in amounts sufficient to make a required payment under the Series 2016A Notes due to the imposition of exchange controls or other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Series 2016A Notes will be made in U.S. dollars until the euro is again available to the Company or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. dollar/euro exchange rate available on or prior to the second Business Day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment in respect of the Series 2016A Notes so made in U.S. dollars will not constitute an Event of Default under the Series 2016A Notes or the Indenture. Neither the Trustee nor the Paying Agent shall have any responsibility for any calculation or conversion in connection with the foregoing.


A-4



Principal of, premium, if any, and interest on the Series 2016A Notes will be payable at the office of the Paying Agent or, at the Company’s option, payment of interest may be made by check mailed to the Holders of the Series 2016A Notes at their respective addresses set forth in the Security Register; provided that all payments of principal, premium, if any, and interest with respect to the Series 2016A Notes represented by one or more Global Securities deposited with, or on behalf of, the Depositary, and registered in the name of the nominee of the Depositary will be made through the facilities of the Depositary.
REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

Southern Power Company, a Delaware corporation (the “Company”, which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to ________________________________, or registered assigns, the principal sum of ______________________________________ EURO (€______________) on the Stated Maturity shown above (or upon earlier redemption), and to pay interest thereon from the Original Issue Date shown above, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, annually in arrears on the Interest Payment Date as specified above, commencing on June 20, 2017, and on the Stated Maturity (or upon earlier redemption) at the rate per annum shown above until the principal hereof is paid or made available for payment and at such rate on any overdue principal and on any overdue installment of interest. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date (other than an Interest Payment Date that is the Stated Maturity or on a Redemption Date) will, as provided in such Indenture, be paid to the Person in whose name this Note (the “Note”) is registered at the close of business on the Regular Record Date as specified above next preceding such Interest Payment Date, provided that any interest payable at the Stated Maturity or on any Redemption Date will be paid to the Person to whom principal is payable. Except as otherwise provided in the Indenture, any such interest not

A-3



so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note is registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Notes of this series shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Indenture.
Payments of interest on this Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for this Note shall be computed and paid on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last Interest Payment Date (or the Original Issue Date, if no interest has been paid on the Series 2016B Notes) to, but excluding, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association. In the event that any date on which interest is payable on this Note is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on such date. If the Stated Maturity or any Redemption Date of the Series 2016B Notes falls on a day that is not a Business Day, the related payment of principal, premium, if any, and interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest shall accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day. A “Business Day” shall mean any day, other than a Saturday or Sunday, (i) which is not a day on which banks in The City of New York or London are authorized or obligated by law or executive order to close and (ii) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.
All payments of interest and principal, including payments made upon any redemption of the Series 2016B Notes, will be payable in euro. If, on or after the Original Issue Date, the Company is unable to obtain euro in amounts sufficient to make a required payment under the Series 2016B Notes due to the imposition of exchange controls or other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Series 2016B Notes will be made in U.S. dollars until the euro is again available to the Company or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. dollar/euro exchange rate available on or prior to the second Business Day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment in respect of the Series 2016B Notes so made in U.S. dollars will not constitute an Event of Default under the Series 2016B Notes or the Indenture. Neither the Trustee nor the Paying Agent shall have any responsibility for any calculation or conversion in connection with the foregoing.

A-4



Principal of, premium, if any, and interest on the Series 2016B Notes will be payable at the office of the Paying Agent or, at the Company’s option, payment of interest may be made by check mailed to the Holders of the Series 2016B Notes at their respective addresses set forth in the Security Register; provided that all payments of principal, premium, if any, and interest with respect to the Series 2016B Notes represented by one or more Global Securities deposited with, or on behalf of, the Depositary, and registered in the name of the nominee of the Depositary will be made through the facilities of the Depositary.
REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.
Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note is one of a duly authorized issue of Senior Notes of the Company (the “Notes”), issued and issuable in one or more series under a Senior Note Indenture, dated as of June 1, 2002, as supplemented, including by a Eleventh Supplemental Indenture (the “Supplemental Indenture”) dated as of June 20, 2016, (the “Indenture”), between the Company and Wells Fargo Bank, National Association (as successor to The Bank of New York Mellon (formerly known as The Bank of New York)), as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures incidental thereto reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes issued thereunder and of the terms upon which said Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof as Series 2016B 1.850% Senior Notes due June 20, 2026 (the “Series 2016B Notes”) which is unlimited in aggregate principal amount. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.
The Series 2016B Notes will be subject to redemption at the option of the Company, in whole or in part, at any time and from time to time, upon not less than 30 nor more than 60 days’ notice, at Redemption Prices equal to the greater of (i) 100% of the principal amount of the Series 2016B Notes being redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Series 2016B Notes being redeemed (not including any portion of such payments of interest accrued to the Redemption Date) discounted (for purposes of determining present value) to but not including the Redemption Date on an ACTUAL/ACTUAL (ICMA) day count basis, at the applicable Comparable Government Bond Rate plus 27.5 basis points, plus, in each case, accrued and unpaid interest on the Series 2016B Notes being redeemed to but not including the Redemption Date.
If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any taxing authority in the United States), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after the date of the issuance of the Series 2016B Notes, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, the Company will become obligated to pay additional amounts as described in Section 108 of the Supplemental Indenture with respect to the Series 2016B Notes, then the Company may at any time at its option redeem, in whole, but not in part, the outstanding Series 2016B Notes on not less than 30 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of the principal amount of the Series 2016B Notes, together with accrued and unpaid interest thereon to but not including the Redemption Date.
“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by the Company, a bond that is a direct obligation of the Federal Republic of Germany (“German government bond”), whose maturity is closest to the maturity of the Series 2016B Notes, or if such independent investment bank in its discretion determines that such similar bond is not in issue, such other German government bond as such independent investment bank may, with the advice of three

A-8



brokers of, and/or market makers in, German government bonds selected by the Company, determine to be appropriate for determining the Comparable Government Bond Rate.
“Comparable Government Bond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the Comparable Government Bond on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment bank selected by the Company.
The Trustee shall not be responsible for the calculation of the Redemption Price with respect to any redemption pursuant to Section 107(a) of the Supplemental Indenture. The Company shall calculate such Redemption Price and promptly notify the Trustee and the Paying Agent thereof.
In the event of redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the surrender hereof.
The Series 2016B Notes will not have a sinking fund.
If an Event of Default with respect to the Notes of this series shall occur and be continuing, the principal of the Notes of this series may be declared due and payable in the manner, with the effect and subject to the conditions provided in the Indenture.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes of each series at the time Outstanding, on behalf of the Holders of all Notes of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.
No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar and duly executed by, the Holder hereof or his attorney duly authorized in

A-9



writing, and thereupon one or more new Notes of this series, of authorized denominations and of like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Note for registration of transfer, the Company, the Trustee, the Paying Agent, the Transfer Agent, the Securities Registrar and any agent of the Company, the Trustee, the Paying Agent, the Transfer Agent or the Securities Registrar may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee, the Paying Agent, the Transfer Agent, the Securities Registrar nor any such agent shall be affected by notice to the contrary.

As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the Holder surrendering the same upon surrender of the Note or Notes to be exchanged at the office or agency of the Company.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to Southern Power Company (the “Company”) in connection with the Registration Statement on Form S-3 (Registration Statement No. 333-205680) filed with the Securities and Exchange Commission (the “Commission”) on July 15, 2015, as amended, and declared effective by the Commission on September 10, 2015 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”), relating to €600,000,000 aggregate principal amount of the Company’s Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”). The Notes will be issued pursuant to the Senior Note Indenture dated as of June 1, 2002 between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as heretofore supplemented and as further supplemented by a Tenth Supplemental Indenture dated as of June 20, 2016 (collectively, the “Indenture”).
We have examined the Registration Statement and the Indenture, which has been filed with the Commission as an exhibit to the Registration Statement. We have also examined the originals, or duplicates or certified or conformed copies, of such records, agreements, instruments and other documents and have made such other and further investigations as we have deemed relevant and necessary in connection with the opinions expressed herein. As to questions of fact material to this opinion, we have relied upon certificates of public officials and of officers and representatives of the Company.
In rendering the opinions set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We have also assumed that the Indenture is the valid and legally binding obligation of the Trustee.

Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that the Notes are valid, binding and legal obligations of the Company, except as may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and to general principles of equity, whether considered in a proceeding at law or in equity.

RE:      Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to the underwriters in connection with the Registration Statement on Form S-3 (Registration Statement No. 333-205680) (the “Registration Statement”) relating to €600,000,000 aggregate principal amount of Southern Power Company’s (the “Company”) Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”). The Notes will be issued pursuant to the Senior Note Indenture dated as of June 1, 2002 between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as heretofore supplemented and as further supplemented by a Tenth Supplemental Indenture dated as of June 20, 2016 (collectively, the “Indenture”).

We have examined the Registration Statement and the Indenture, which has been filed with the Securities and Exchange Commission (the “Commission”) as an exhibit to the Registration Statement. We have also examined the originals, or duplicates or certified or conformed copies, of such records, agreements, instruments and other documents and have made such other and further investigations as we have deemed relevant and necessary in connection with the opinions expressed herein. As to questions of fact material to this opinion, we have relied upon certificates of public officials and of officers and representatives of the Company.

In rendering the opinions set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We have also assumed that the Indenture is the valid and legally binding obligation of the Trustee.

Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that the Notes are valid, binding and legal obligations of the Company, except as may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to Southern Power Company, a Delaware corporation (the “Company”), in connection with the preparation and filing by the Company of a Registration Statement on Form S-3, as amended (Registration Statement No. 333-205680)(the “Registration Statement”), including the Prospectus dated September 10, 2015 (the “Prospectus”) included in the Registration Statement, and a Prospectus Supplement dated June 13, 2016 (the “Prospectus Supplement”), each as filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”). The Prospectus and the Prospectus Supplement describe the Company’s offer to sell €600,000,000 aggregate principal amount of the Company’s Series 2016A 1.000% Senior Notes due June 20, 2022 (the “Notes”). This opinion relates to the discussion set forth under the caption “UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS” of the Prospectus Supplement. All capitalized terms used but not defined herein shall have the meanings ascribed to them in the Prospectus Supplement.

In connection with the preparation of our opinion, we have examined such documents and other materials as we have deemed appropriate, including, but not limited to, the Prospectus and the Prospectus Supplement. We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such corporate records, officer’s certificates and other documents and have made such investigations of law as we have deemed necessary or appropriate as a basis for the opinion expressed below. Our opinion assumes (i) the accuracy of the facts contained in the Prospectus and the Prospectus Supplement and other materials examined by us and (ii) the consummation of the offer to sell the Notes in the manner contemplated by, and in accordance with the terms set forth in, the Prospectus and the Prospectus Supplement.

Based upon and subject to the foregoing, the discussion contained in the Prospectus Supplement under the caption “UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS,” subject to the limitations described therein, constitutes the opinion of Troutman Sanders LLP. There can be no assurance that changes in the law will not take place that could affect such United States federal income tax consequences, or that contrary positions may not be taken by the Internal Revenue Service. In the event any of the facts, statements,

The authorities upon which our opinion relies are subject to change with potential retroactive effect. Nevertheless, by rendering this opinion we undertake no responsibility to advise you of any change in United States federal income tax laws or the application or interpretation thereof that could affect our opinion.

We hereby consent to the filing of this letter as an exhibit to the Registration Statement and to the reference to us in the Registration Statement under the caption “Legal Matters” and in the Prospectus and the Prospectus Supplement.
