Virginia orders data centers to pay for power lines, cutting costs for households

Abigail Spanberger won a ruling this month that shifts the biggest construction project on earth. Virginia's governor persuaded the State Corporation Commission to require data centers to pay the full cost of transmission lines built exclusively for them.

Her office forecasts that ratepayers will save hundreds of millions of dollars as a result, according to WSET on August 6. This order intervenes because, until now, the data center industry did not cover these costs.

The order serves as a release valve for the most unusual fact this August: despite an unprecedented computing build-out, data centers have not lost power while waiting for electricity, and the cost of queuing and spare grid capacity lands on household bills, years before any delay makes the news.

The money already spent

PJM Interconnection operates the wholesale power market in thirteen states, including Northern Virginia, the world's densest data center cluster. Its independent market monitor, Monitoring Analytics, calculated in a remio summary on July 16 that data center demand—current and projected—raised system costs by $23.1 billion across three capacity auctions. These obligations run through May 2028 and cannot be unwound by regulators.

Amazon, Google, Meta, Microsoft, OpenAI, Oracle, and xAI have all stated their buildings will not shift costs onto household bills, but a substantial sum is already committed.

PJM's most recent capacity auctions cleared at the regulatory price cap of $329.17 per megawatt-day, ten times the price two years ago ($28.92), based on results for the 2025-26 delivery year.

Data centers constitute roughly half of all new American electricity demand, according to Fortune via SmarterArticles. Berkeley Lab's July 21 Queen Zone report projects they could consume 11.8% of US electricity by 2030 under its reference case. Generators, transmission owners, and fuel suppliers receive the difference between historic and new demand, while households lend them the capital.

Household electric bills

The residential side is measurable. The National Energy Assistance Directors Association predicts the average American home will spend $792 on electricity from June to September 2026, 10.5% higher than last summer's $717 and nearly 40% above the 2020 level. This forecast appeared in The Queen Zone on July 21.

The Energy Information Administration expects residential prices to rise 5.7% in 2026, reaching about 18.51 cents per kilowatt-hour in the third quarter, per EIA figures also carried by The Queen Zone on July 21. While heat and old rates explain most of the increase, data centers add pressure wherever the grid is tight, making the same summer bill more expensive in Ashburn, Virginia than in Vermont.

Hyperscalers require speed to avoid rivals gaining ground and thus accept rate classes that enable quick substation approvals. Utilities seek growth in their rate base, especially Dominion Energy, whose proposed $67 billion merger with NextEra Energy would create the world's largest regulated utility, as WSET reported on August 6. State regulators aim for re-election without headlines about shutoff notices. Grid operators like PJM prioritize reliability and price signals.

Washington wants both the AI build-out and the support of those who pay its externalities. In July, President Trump promised, "big tech, not families," will bear data center energy costs, Reuters reported via US News on July 22.

Political consequences have already arrived. Independence, Missouri, a city near Kansas City, will vote in September on removing its city manager over a data center land deal. Yukon, Oklahoma, holds a mayoral recall in November for the same reason, according to the New York Times on August 19. A University of Pennsylvania survey published by WHYY revealed sharp increases in opposition to new data centers among both Democrats and Republicans. Last November in Georgia, Democrats unseated two Republican utility commissioners over electric bills.

When the bill arrives before the benefit, the politician who backed the deal becomes liable.

A historical parallel emerges: around 2000, Pacific Northwest aluminum smelters, built on cheap federal hydropower, shut down when California's crisis forced spot prices higher, leaving ratepayers with fixed costs. Here, too, large customers negotiate favorable rates, utilities socialize network upgrades, and routine customers end up funding flexibility. The difference is direction. With AI loads compounding rather than departing, the subsidy debate happens as the load grows instead of after it disappears.

Hyperscalers increasingly procure their own electricity. Microsoft contracted to restart the Three Mile Island reactor for its load; Amazon, Google, and Microsoft are funding new nuclear and renewable projects directly. In ERCOT, Texas’s grid, large flexible loads were designed to cover their own costs, enabling Governor Greg Abbott to pause data center approvals without upsetting consumers, as TechGolly reported on August 3. Where buyers must provide their own power, household bills remain unaffected. The issue is regional, concentrated where legacy rules allow large loads to share common tariffs.

States are beginning to follow Virginia’s lead. The SCC’s tariff approach is easily exported, and Dominion’s proposal for dedicated data center rates indicates utilities are moving preemptively rather than waiting for regulators.

Next, hyperscalers expand self-supply, buying reactors, gas turbines, and renewable contracts, shifting billions from regulated utilities to unregulated producers and equipment suppliers like GE Vernova.

If data centers leave the shared tariff, the fixed grid costs they justified are distributed across fewer customers, pushing rates higher for households and feeding the backlash policymakers hoped to avoid.

Residential and small-business ratepayers within PJM and similar markets pay through capacity charges locked in until May 2028. Incumbent generators who succeeded in the auctions benefit, as do transmission owners whose rate base increased and gas turbine makers selling amid a shortage.

The dispute centers on the margin between them, and Virginia’s ruling this month moved several hundred million dollars toward households.
