Includes payments required by PPAs for capacity rights and minimum quantities of MWhs required to be purchased. As a result of an amendment to shorten the term of the DAEC PPA, Alliant Energy’s and IPL’s amounts include minimum future commitments related to IPL’s purchase of capacity and the resulting energy from DAEC through September 2020, and do not include the September 2020 buyout payment of $110 million.
|
(b)
|
Corporate Services entered into system-wide coal contracts on behalf of IPL and WPL that include minimum future commitments. These commitments were assigned to IPL and WPL based on information available as of June 30, 2019 regarding expected future usage, which is subject to change.
|
(c)
|
Includes individual commitments incurred during the normal course of business that exceeded $1 million at June 30, 2019.

In March 2019, IPL filed requests with the IUB to increase annual base rates for its Iowa retail electric and gas customers, which were based on a forward-looking test period that includes 2020. IPL concurrently filed for interim retail electric rates based on a 2018 historical Test Year, which were implemented effective April 1, 2019. Intervenor testimony was filed in August 2019 addressing, among other things, the return on common equity percentage used to calculate the interim rate increase, as well as various positions on rate design and revenue requirement, including authorized returns on production tax credits carryforwards, for final rates. Refer to Note 2 for details.

In March 2019, IPL placed approximately 470 megawatts of new wind generation in service at the Upland Prairie and English Farms wind sites. IPL’s retail electric customers began to see the rate impacts of this renewable generation with the interim electric rates effective April 1, 2019.

|
In March 2019, the IUB approved IPL’s energy efficiency plan for 2019 through 2023, which provides direct financial savings to customers and provides cost-effective options to help electric and gas customers reduce their energy usage. The energy efficiency costs, which are lower than previous energy efficiency plans, are reflected on electric customer bills beginning June 2019.

In January and March 2019, AEF, a subsidiary of Alliant Energy, purchased two freight management companies.

|
In June 2019, WPL issued $350 million of 3.00% debentures due 2029. The net proceeds from the issuance were used by WPL to reduce its outstanding commercial paper and retire its $250 million 5% debentures that matured in July 2019.

|
IPL’s interim retail electric base rate increase effective April 1, 2019 was reduced by anticipated production tax credits for IPL’s new wind generation placed in service in March 2019. This reduction in revenue requirement is expected to be offset by a reduction in income tax expense resulting from production tax credits recognized from the new wind generation.

2.

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

|
4.
|
The registrant’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
|
a)
|
Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in which this report is being prepared;
|
b)
|
Designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles;

Evaluated the effectiveness of the registrant’s disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and

Disclosed in this report any change in the registrant’s internal control over financial reporting that occurred during the registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting; and
|
5.
|
The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the registrant’s auditors and the audit committee of the registrant’s board of directors (or persons performing the equivalent functions):
|
a)
|
All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and
