Harry Quarls Joins ESS Board of Directors as Chairman
Energy industry veteran to further accelerate growth

WILSONVILLE, Ore. – August 29, 2023 - ESS Tech, Inc. (“ESS”) (NYSE: GWH), a leading manufacturer of long-duration energy storage (LDES) for commercial and utility-scale applications, today announced Harry Quarls has joined the ESS Board of Directors as Chairman. Michael Niggli, the ESS Founding Board Chairman, will remain on the board to assist with this transition and continue providing insights from his four decades as a utility executive.
With over 40 years of energy experience, Mr. Quarls brings considerable strategic, financial, transactional, and energy investing experience to ESS as the company continues to scale to meet global demand for LDES. Over his long and storied career, Quarls served as a Managing Director at Global Infrastructure Partners, leading their efforts in North American energy midstream investments, and as Managing Director and practice leader for Global Energy as well as a member of the board of directors at Booz & Company.
“We are thrilled to bring someone of Harry’s stature to the board of ESS,” said Niggli. “The company is making strong progress and delivering the energy storage products that customers need. Adding Harry to the team will prove invaluable as we continue to expand our capacity and scale to achieve the full market potential of our patented, safe and cost-effective long duration storage solutions.”
“Harry’s long career advising and leading successful, growing companies spans many pivotal transformations in the energy sector,” said Eric Dresselhuys, CEO of ESS. “Today, the industry is once again at a pivotal moment, and long-duration energy storage represents one of the most important growth opportunities in the global transition to clean energy. I look forward to Harry’s strategic thinking, global partnering and experience growing successful energy and infrastructure businesses as ESS scales to meet global demand.”
“The transition to new, cleaner forms of energy is already underway. As it accelerates in coming years, it is clear that the switch to renewable energy sources will require large volumes of long-duration energy storage to deliver the reliable, clean energy the world demands,” said Quarls. “ESS is perfectly positioned to meet this demand with proprietary technology that is readily scalable and which leverages flexible, accessible supply chains. I am excited to join ESS during this period of growth to drive world-class shareholder value.”
Mr. Quarls currently serves as Chairman of CHC Helicopter and Key Energy Services as well as a Director for Seadrill Ltd.  He has served in Leadership positions on numerous Boards including most recently FlexSteel Pipe, Mesquite Energy and EP Energy. He holds BS/ScM degrees in Chemical Engineering  from Tulane University and MIT, respectively,  and a M.B.A. from the Stanford Graduate School of Business.
