The intervention is a sign that the deal will not get a quiet ride through the review process.
If it closes, the combined company would become the world's largest regulated electric utility.
A regulated utility is a power company that the state lets operate as a monopoly in exchange for tight control over what it can charge customers. NextEra is based in Florida, while Dominion is Virginia's main regulated utility.
For Spanberger, that combination is exactly the problem. She does not think Virginians should have to trust an out-of-state owner when their monthly bills are on the line.
Spanberger won the governorship in 2025 after campaigning to reduce electricity bills. Dominion supplies power to northern Virginia, home to the world's biggest data center market, and voters increasingly blame data centers for higher utility costs.
Data centers are the giant buildings full of servers that run the apps and websites everyone uses. When you stream a show or back up photos to the cloud, a data center somewhere is doing the heavy lifting, and it is using a lot of power to do it.

That appetite for electricity has become a flashpoint in Virginia politics. The fight over this merger is, at its core, a fight about who should pay for all that power.
In an opinion piece for The Washington Post, she made her position clear. "As a Virginian, I am deeply skeptical about whether selling our primary, state-regulated utility to an out-of-state company is good for the commonwealth," she wrote.
The State Corporation Commission is the panel that oversees utilities in Virginia. It will review the transaction and may approve it, reject it, or set conditions.
The governor's intervention lets her office flag concerns, request information, and state what benefits residents should expect, while the final decision stays with the commission.
What the governor says during the review could carry real weight with the people making the call.
Spanberger said she expects the deal to provide ongoing, long-term savings on Virginians' energy bills. "If two large corporations stand to benefit financially from this merger, so, too, should the Virginians who pay the bills," she wrote.
"I have serious questions about what this deal would mean for us," she added. "That is why any potential deal must deliver a more affordable energy bill with sustained, long-term energy cost savings."
The market had a muted reaction, but the move still registered.
For your portfolio, the lesson is that a deal can look finished and still pick up political weight. Utility mergers are not just about balance sheets; they are about customer bills, and customers vote.
For Virginians, the stakes are more personal than a stock ticker. Whatever the commission decides will shape what they pay to keep the lights on for a long time.
The review could go several ways. But the governor just made sure the commission will hear the people who pay the bills.
