Dominion Energy is revamping its executive leadership team.

Tom Farrell, Dominion’s chairman, president and chief executive officer, will become the company’s executive chairman effective Oct. 1, the utility recently announced. Robert Blue, Dominion’s executive vice president and co-chief operating officer, will be promoted to president and chief executive officer. Blue will report to Farrell, who will continue to serve as chairman of the board.

Diane Leopold, executive vice president and co-chief operating officer, will be promoted to Dominion’s sole chief operating officer. In that role, she is responsible for all the company’s operating segments and will report to Blue. Ed Baine will be promoted to president of Dominion Energy Virginia. He will report to Leopold.

Farrell joined Dominion in 1995, was promoted to president and chief executive officer in 2006 and added the role of chairman in 2007. Before joining the company in 2005, Blue was director of policy for former Gov. Mark Warner, an attorney and a law clerk for the U.S. District Court for the Eastern District of Virginia. He also is a member of the University of Virginia Board of Visitors.

“There is no established timeframe for my role as executive chair, and I look forward to continuing to serve the company on behalf of our shareholders, customers and communities,” Farrell said in an announcement. “I will be particularly focused on continuing to develop our strategic plan and Dominion’s leadership in the new clean energy economy.”

Leopold joined Dominion in 1995 and became an officer in 2004. She has held a wide range of executive roles in both the electric and natural gas sectors of the company. Baine joined the company in 1995 and has held engineering, operational and management positions.

Charlene Whitfield will succeed Baine as senior vice president of power delivery. In her new role, she will oversee Dominion Energy Virginia’s electric transmission, distribution and customer solutions business. Whitfield joined the company in 1982 and is being promoted from vice president of distribution operations. Richmond-based Dominion has more than seven million electricity and natural gas customers in 20 states.
