ALEXANDRIA, Va. — Rep. Don Beyer and four other Virginia Democrats in the House asked the State Corporation Commission on Thursday to reject NextEra Energy’s proposed $67 billion acquisition of Dominion Energy “in its current form,” adding the federal delegation to a list of opponents that already includes the governor, the attorney general, the commission’s own staff and the City of Alexandria.

“As proposed, we do not believe the merger is in the public interest,” Beyer, Jennifer McClellan, Suhas Subramanyam, Eugene Vindman and James Walkinshaw wrote in a four-page letter submitted ahead of Thursday’s deadline for public comment. The joint petition, they said, “lacks the structural protections necessary to prevent material harm.”

The commission must find that “adequate service to the public at just and reasonable rates will not be impaired or jeopardized” before it can approve a change of control. The letter argues the companies haven’t met that test.
