The White House on Thursday said it intends to nominate two Democrats and a Republican to be commissioners on the Federal Energy Regulatory Commission, a first step in filling the agency’s five seats.

The nominees are Judy Chang, a managing principal at the Boston-based Analysis Group and former undersecretary of energy and climate solutions for Massachusetts; David Rosner, a FERC energy industry analyst on loan to the Democratic staff of the U.S. Senate Energy and Natural Resources Committee; and Lindsay See, the West Virginia solicitor general. See is a Republican; Chang and Rosner are Democrats…

“Rosner and Chang fit the conventional mold of candidates who have engaged extensively at FERC,” said Devin Hartman, director of energy and environmental policy at the R Street Institute, a free market oriented think tank. “See’s background is less common for a FERC nominee, and reflects Republicans’ concern of federal overreach of executive agencies.”
