Connecticut's attorney general and governor said they are intervening in a federal review of a $67 billion merger between NextEra Energy and Dominion Energy, arguing the deal would eliminate competition for a critical power source and harm consumers.
The combined company would control all of New England's nuclear power generation, concentrating a resource that currently provides a majority of Connecticut's electricity. The merger would create one of the world's largest utility companies with approximately 10 million customer accounts and 110 gigawatts of generating capacity. NextEra Energy owns Seabrook nuclear power plant in New Hampshire, while Dominion Energy operates Connecticut's Millstone Nuclear Power Station.
Attorney General William Tong said the intervention targets the Federal Energy Regulatory Commission, which is reviewing the transaction along with the U.S. Department of Justice and the U.S. Nuclear Regulatory Commission. Virginia, North Carolina, and South Carolina must also approve the deal. "The last thing we need is consolidated corporate control over the core of Connecticut's energy supply," Tong said. "I cannot support this merger."
Connecticut officials cited the state's history of high utility costs, with residents already paying some of the highest rates in the nation. Governor Ned Lamont said Connecticut has fought aggressively on behalf of ratepayers, with state agencies blocking over $1 billion in requested rate increases from utilities. Connecticut's existing nuclear power contracts have saved ratepayers more than $250 million in 2025 and $280 million through August 2026 through fixed pricing that protects against volatile fossil fuel costs.
