Utility filings show AI data center surge pulling new gas plants into rate base
Daniel Simon ·
Big Tech’s race to scale artificial intelligence is reshaping U.S. power planning. Utility filings reviewed by TechGlobal show proposed gas generation and grid upgrades linked to large data center loads that include facilities for Amazon, Microsoft, Google, and Meta.
The costs are set to flow into regulated rate base for years. Public records provide clearer detail than corporate sustainability reports on how the buildout will be paid for.
What the filings show
Dominion Energy Virginia’s 2023 Integrated Resource Plan to the State Corporation Commission, case PUR-2023-00066, identifies hyperscale data centers in Northern Virginia as a primary driver of load growth. The plan models additional peaking capacity and extensive transmission upgrades to serve clusters in Loudoun County.
PJM Interconnection’s 2024 Long-Term Load Forecast cites materially higher demand in the Dominion zone that it attributes to data center expansion. PJM’s planning materials detail interconnection constraints and new high-voltage lines under study to serve that growth.
Georgia Power’s 2024 Integrated Resource Plan Update in Public Service Commission Docket 44160 requests accelerated capacity additions and new procurement tied to unexpected large load additions. Testimony in that docket points to data center commitments and associated timing, and the commission approved an expansion of near-term resources.
The Tennessee Valley Authority’s 2024 Integrated Resource Plan notes rapid load growth from industrial customers and data centers across its service territory. TVA’s board has advanced multiple gas projects since 2023 while also signing new long-term renewables contracts.
Independent projections line up with these filings. The International Energy Agency’s 2024 report on data centres and AI estimates global data center electricity use could reach 620 to 1,050 terawatt-hours in 2026, up from about 460 terawatt-hours in 2022. U.S. grid planners have begun to reflect that demand in capacity and transmission plans.
Who pays and what is disclosed
In all three territories, proposed plants and wires are recovered through regulated rates. Residential and small business customers bear a share of the cost regardless of whether they directly benefit from the new load. Utilities also file confidential special contracts for very large customers, which limit public insight into pricing, curtailment terms, and who gets priority service.
The gap between corporate climate pledges and utility planning is most visible in near-term resource choices. Microsoft, Google, Amazon, and Meta disclose long-term clean energy procurement in sustainability reports and SEC filings, yet the utilities serving their largest campuses are advancing gas peakers to meet near-term reliability needs when renewables and transmission are not in place.
The interconnection backlog complicates alternatives. FERC Order No. 2023 reformed interconnection study processes, but PJM and Southern utilities warn that study queues and upgrades will take years to complete. That timetable aligns with the gas-heavy near-term proposals in the resource plans.
The stakes extend beyond monthly bills. New gas capacity and high-voltage corridors carry local environmental impacts and long-lived cost recovery. Water use for thermal plants and for data center cooling is an additional pressure that state commissions are beginning to assess in dockets linked to these plans.
What happens next is on the regulatory calendar. Virginia’s State Corporation Commission continues to review Dominion’s resource choices in annual updates tied to case PUR-2023-00066. Georgia Power’s next integrated resource filing cycle is scheduled under Docket 44160 procedures. PJM’s capacity auctions and transmission planning meetings in 2026 will show how much of the new load converts into committed steel in the ground, and how quickly ratepayers will be asked to fund it.
