Federal Energy Regulatory Commission Chairman Jon Wellinghoff, 63, has presented his resignation letter to President Barack Obama, according to reports.
Wellinghoff will remain in his position until a replacement is named and approved by the Senate.
The American Wind Energy Association (AWEA) released a statement calling Wellinghoff a “pioneer of change.”
“Chairman Wellinghoff is a pioneer and strong champion of change overseeing the U.S. electric grid. He respected the role of states, utilities, and various other stakeholders while challenging all of the players to consider new ways of opening the grid to expansion and innovation. He deserves a lot of credit for the much-needed transmission infrastructure expansion that is taking place around the country.”
