A mega merger would create the world's largest regulated electric utility by market capitalization and lock in a shift in who the utility actually serves, with AI data centers in Northern Virginia already taking 28 percent of Dominion's electricity.
Dominion Energy's board already works for AI data centers. On May 18, NextEra Energy, one of the largest US electric utilities and the world's biggest renewable-power company, agreed to acquire Dominion in a deal worth roughly $67 billion. Announced as a response to "unprecedented" AI-driven electricity demand, the combination would create the largest regulated electric utility by market capitalization, joining NextEra's renewables-heavy Florida fleet with Dominion's Virginia, North Carolina, and South Carolina territories, including the utility that already feeds the world's densest cluster of AI data centers (NextEra–Dominion press release).
What the announcement does not say is more important than what it does. Dominion's wholly owned subsidiary already sells about 28 percent of its electricity to AI data centers in Northern Virginia, a corridor that runs through Ashburn and Loudoun County and now hosts 133 of Virginia's 609 data centers (American Action Forum analysis). The number is so large that the region, sometimes called "Data Center Alley," has effectively become Dominion's anchor tenant. The merger is the moment the franchise catches up to the customer mix.
The political universe of a regulated-utility merger is normally the ratepayer base. In this case that means Dominion's 3.6 million residential and small-business customers across three states, served by 30.7 gigawatts of generating capacity and 80,400 miles of distribution lines (NextEra–Dominion press release). But the capex, siting priorities, reliability investments, and rate-case posture of Dominion's board have already tilted toward the data-center class. The merger formalizes that tilt at the parent-company level, giving one combined entity control over the generation, transmission, and retail franchise that feeds both populations at once.
Approval runs through a gauntlet that has not fully formed yet. The deal needs sign-off from public utility commissions in Virginia, North Carolina, and South Carolina, plus the Federal Energy Regulatory Commission, which oversees wholesale competition in PJM, the regional grid operator that serves most of the Eastern Seaboard (American Action Forum analysis). FERC's review will likely focus on whether the combined firm can exercise market power in PJM's wholesale capacity auctions. The question has a real precedent: an empirical study of PJM and other US power markets by the economics firm CRA International found measurable price effects from generator-withholding behavior in tight market conditions (CRA International, "Economic Evidence of Market Power and Market Manipulation in Energy Markets"). The 2020 paper predates the current AI load surge, so its framework is illustrative rather than current, but it is the methodology FERC is most likely to import into the review.
State commissions will fight a more granular fight. The Virginia State Corporation Commission, in particular, has already shown it is willing to require concessions on data-center rate design, pushing Dominion toward tariff structures that make hyperscalers pay more of the grid costs they impose rather than socializing them onto residential customers. Approval here is likely to come with forced divestitures of generating assets, ringfencing of transmission planning, or both. Dominion's existing 28 percent data-center exposure becomes the test case for what conditions are enough.
If the merger closes on the terms announced, the combined NextEra–Dominion franchise will not be a regulated utility that happens to enable AI. It will be the country's first utility formally built around an AI-anchor customer class, with the regulator's blessing and a rate base that has priced the inversion in. What to watch next: the timing of Virginia's formal filing, FERC's market-power methodology in the PJM footprint, and whether any of the three state commissions moves first to require structural divestitures rather than behavioral commitments. The arithmetic of who actually pays for the buildout runs through every one of those dockets.
