The PJM Interconnection Board of Managers has appointed David Mills to serve as PJM’s fifth permanent president and CEO effective May 1, 2026.
Mills has served on the PJM Board of Managers since 2021 and as chair of the PJM Board since May 2025. He has also served as Interim President and CEO of PJM since January 2026.
Mills has a proven track record of strategic leadership in the power and natural gas industries as both an executive and consultant, the grid operator said.
He is the former senior vice president of policy and energy supply with Puget Sound Energy, where he also served as chief strategy officer.
Mills previously worked for the U.S. Department of Energy’s Bonneville Power Administration.
With this transition, Mills is resigning from his seat on the Board as a voting member and as the Board chair, effective at the end of the day on April 30, but will continue to serve on the Board as a non-voting member of the Board by virtue of his office as President and CEO.
Board member Paula Conboy was elected by the Board on April 29 as chair-elect, and she ascends to the chair until the election of a chair at the Annual Meeting of the PJM Board on May 15.
