Longtime energy lawyer Kevin McIntyre was confirmed last month as chairman of the Federal Energy Regulatory Commission. His installation Thursday brings the commission to a full five members.
The commission was without a quorum for much of the year and unable to make decisions on interstate pipelines and other projects worth billions of dollars.
McIntyre arrives as the commission considers a Trump administration plan to bolster struggling nuclear and coal-fired power plants.
The plan by Energy Secretary Rick Perry would reward nuclear and coal-fired power plants for adding reliability to the nation's power grid.
Action by FERC is expected next week.
