Key Takeaways:
Dominion Energy's fuel costs in Virginia rose nearly 90% in five years as data-center-driven demand left the utility exposed to volatile wholesale power prices.
The State Corporation Commission approved rate increases of $11.24 a month for residential customers in 2026 and another $2.36 in 2027, passing through higher fuel and transmission costs, the regulator said. The increases follow a separate order directing Dominion to assign transmission costs directly to data centers rather than spreading them across the residential base.
Data centers now account for about 21 percent of Dominion's electricity sales, a share projected to double by 2040, with the utility forecasting 13.3 gigawatts of demand by 2038. Wholesale prices near major data center hubs have climbed as much as 267 percent over five years, and Virginia imports 36 percent of its power, the largest share of any state.
Virginia's data center corridor, which handles an estimated 70 percent of global internet traffic, has driven the surge in power demand that leaves Dominion buying more electricity on wholesale markets. The utility's fuel expenses have climbed nearly 90 percent since 2021, according to company filings, even as it relies on natural gas for 54 percent of generation and imports power from coal-heavy states such as West Virginia.
The cost pressure extends beyond Dominion. Goldman Sachs Research projects global data center power demand will grow 160 percent by 2030, straining grids across the country and pushing utilities to raise capital spending. Dominion has said it will need to expand transmission and generation capacity to serve the concentrated demand in Northern Virginia's Loudoun and Prince William counties, where most of the state's data centers sit. A state audit projects data center-driven demand could add $14 to $33 a month to typical residential bills by 2040.
The higher rates will test whether Dominion can pass through costs without eroding demand from its largest customers. Investors will watch the utility's next earnings report for updated fuel-cost guidance and any revision to its grid investment plan, with the PJM capacity auction in the coming months offering a read on wholesale prices. The fuel-cost trajectory also raises questions about how much of the burden utilities can shift to hyperscalers before those customers seek cheaper power markets elsewhere.
