AI data center expansion is prompting utilities and regulators to adopt new cost protections, according to an industry analysis. Independent research associates earlier facility growth with higher electricity rates, while federal forecasts show further price increases. Decisions in Michigan, Ohio and Virginia illustrate how household bills could be affected.
Key Takeaways
- A report highlighted more than 20 data center proceedings decided in 16 states during 2025 and 2026
- Lawrence Berkeley National Laboratory estimates data centers could use 11.8% of U.S. electricity by 2030 in its reference scenario
- Federal forecasters expect residential electricity prices of 18.2 cents per kilowatt-hour in 2026, up from 17.3 cents in 2025
- A June study associated earlier data center openings with a 2.1% increase in residential electricity prices
- Michigan approved a 20-year Google electricity agreement with an 80% minimum billing commitment
New contracts are turning estimates of electricity demand into enforceable payment obligations. When Michigan approved power agreements for a Google facility on October 1, Michigan Public Service Commission Chair Dan Scripps said the safeguards would ensure that “other customers aren’t subsidizing this large addition to the state’s energy grid.”
AI Data Center Expansion Brings New Cost Safeguards
Charles River Associates reviewed more than 20 regulatory proceedings decided across 16 states in 2025 and 2026. Its October report, prepared for the Edison Electric Institute, identified minimum charges, longer contracts, financial guarantees and payments for dedicated infrastructure.
These provisions address a risk: utilities might construct equipment for a data center that ultimately uses less electricity than requested or closes before the costs are recovered. The report says large customers could reduce rates for others when their payments adequately cover grid expenses.
That result is not guaranteed for every project. Because the research was prepared for a utility industry association, its conclusions warrant comparison with independent studies of historical prices.
The scale of potential demand explains the attention. Lawrence Berkeley National Laboratory estimated in June that data centers could account for 11.8% of total U.S. electricity consumption in 2030 under a reference scenario, with modeled outcomes ranging from 9.5% to 15.3%.
A previous laboratory report estimated their share at 4.4% in 2023. The newer forecasts depend on assumptions about server shipments, power use and cooling efficiency. Growing AI infrastructure build-outs therefore create planning demands before every proposed facility becomes operational.
Electricity Bill Forecasts Show Multiple Cost Pressures
The U.S. Energy Information Administration’s October 6 outlook forecasts residential electricity prices averaging 18.2 cents per kilowatt-hour in 2026 and 18.7 cents in 2027, compared with 17.3 cents in 2025.
It also projects 2026 wholesale prices averaging $52 per megawatt-hour across 11 monitored hubs, up 11% from 2025. The agency expects a 41% rise in the PJM regional market, with weather affecting prices in several areas. Its outlook also anticipates further growth in commercial-sector electricity use next year.
Wholesale costs are only part of residential bills, which also reflect generation, transmission, distribution and capacity-market expenses. Seasonal demand, illustrated by summer electricity bill forecasts, can contribute to higher costs without proving that data centers caused any particular increase.
Independent research nevertheless suggests data center development can affect rates. A June working paper published by the Massachusetts Institute of Technology’s Center for Energy and Environmental Policy Research studied new facilities from 2010 through 2024.
The authors associated data center entry with 2.7% higher average retail electricity prices, including 2.1% for households. Effects were larger among shareholder-owned utilities and in states with deregulated electricity generation.
Those historical estimates do not establish a specific charge on 2026 bills. They also address a different question from the Charles River Associates review, which examined safeguards approved in more recent proceedings.
Michigan, Ohio and Virginia Set Terms for Large Users
On October 1, the Michigan Public Service Commission conditionally approved electricity agreements between DTE Electric and Google for a data center in Van Buren Township.
The 20-year agreement requires minimum billing based on 80% of contracted demand, even when actual use is lower. Financial assurances and early termination provisions address the possibility of unrecovered costs, with Google responsible for at least 15 years of minimum payments if the agreement ends early.
Google must also pay for renewable generation and battery storage associated with the project. The Michigan commission’s authority covered electricity service terms, not whether the facility could be built.
Ohio established a separate data center tariff for AEP Ohio. The Public Utilities Commission of Ohio requires measures including collateral, minimum demand charges, lengthy contracts and early-exit fees to limit costs being shifted to other customers.
Virginia’s State Corporation Commission approved a new rate class for customers requiring at least 25 megawatts, effective January 1, 2027. Certain large users face minimum charges tied to 85% of contracted transmission and distribution demand and 60% of generation demand.
The states use different safeguards. None establishes a single nationwide bill surcharge, and broader electricity price changes remain possible.
Frequently Asked Questions
Does AI data center expansion automatically increase household bills?
No. AI data center expansion does not create a nationwide surcharge, and any impact depends on utility contracts, local costs and regulatory decisions.
How much electricity could data centers use by 2030?
Lawrence Berkeley National Laboratory estimates 11.8% of U.S. electricity use under its reference scenario, with projections ranging from 9.5% to 15.3%. These are modeled outcomes, not measured future consumption.
Which states have adopted protections for electricity customers?
Michigan, Ohio and Virginia have approved special rates or contracts for large electricity users. The measures include minimum payments and safeguards against shifting costs to existing customers.
Are data centers the only reason electricity prices are rising?
No single cause explains U.S. electricity prices. Federal forecasters also identify weather, fuel costs and expenses for electricity delivery.
