This appointment marks Mills as the fifth permanent leader of PJM Interconnection, which is recognized as the largest electric grid in the nation.

David Mills brings a wealth of experience and knowledge to this pivotal role. Having served on the PJM Board of Managers since 2021, he became the chair of the Board in May 2025. Prior to his appointment as CEO, Mills held the position of Interim President and CEO since January 2026, demonstrating his capability in leading the organization during a crucial transformation phase.

Mills holds a Bachelor of Science degree in economics from Portland State University and is certified by the National Association of Corporate Directors (NACD). He will resign from his voting member position on the Board while continuing to serve non-voting as President and CEO. In his absence as chair, board member Paula Conboy is designated as chair-elect and will lead until the annual election set for May 15.

PJM Interconnection, established in 1927, is responsible for ensuring the reliability of the high-voltage electric power system serving an impressive 67 million people across parts of 13 states and the District of Columbia.
