Residential bills in PJM states could rise $15–$20 monthly as data centers drive 46% of capacity auction costs
Across four recent capacity auctions, AI data centers have added roughly $29 to $30 billion in costs to the electric grid — charges that land directly on your utility bill. That figure, according to Monitoring Analytics, represents about 46 percent of total capacity charges during that period. Data centers now consume around 4 percent of U.S. electricity, and the latest EIA pricing data shows the damage isn’t distributed evenly. Some states are absorbing the hit like a body blow. Others barely feel it.
The Capacity Crunch Behind Your Bill
Grid operators auction off future power supply, and data centers are driving those prices to record highs.
Grid operators like PJM Interconnection — which covers 13 Eastern states and D.C. — hold capacity auctions to ensure enough electricity supply exists, and those costs flow downstream to customers. PJM’s most recent auction will add $6.3 billion to consumer bills over three years, with data-center demand responsible for most of that increase, according to reporting by the New York Times and Utility Dive. As finance analyst Michael Ryan put it, “Ordinary customers are financing infrastructure for some of the richest companies in the world.”

The state-level numbers make that abstract claim concrete:
- Illinois: ~23.85¢/kWh, up ~28% year-over-year — among PJM territory’s fastest risers
- Virginia: ~17.61¢/kWh, up ~15.4% — home to Data Center Alley, one of the world’s densest concentrations of data centers
- Hawaii: ~52.00¢/kWh, up ~26.7% — highest in the nation, though driven by fuel costs and grid isolation, not AI
- Georgia: ~15.84¢/kWh, up ~5.7% — where voter frustration over bills ousted two utility commissioners in 2025
- Texas: ~16.44¢/kWh, up ~5.9% — ERCOT has warned that AI loads could tighten the grid further
Business professor Arie Brish argues data centers should function like major real-estate developments — with binding, pre-negotiated agreements on who funds generation, transmission, and backup capacity before a single server rack goes online. Right now, those infrastructure costs get averaged across everyone’s bill instead. That’s not a market failure. That’s a policy choice.
Pledges vs. Laws — Who’s Actually Protected
Voluntary corporate promises sound reassuring until you read the fine print.
President Trump’s Ratepayer Protection Pledge urges tech companies to cover their own energy costs, and firms like Microsoft and Anthropic have made similar voluntary commitments. The catch: none of these carry legal force or enforcement mechanisms. Meanwhile, according to policy tracker MultiState, 27 states are advancing legislation that would require data centers to fund their own grid expansion. California, Ohio, and Utah have already enacted laws that go further than the federal pledge in both scope and enforceability.
Stopping a data center at a zoning meeting and actually lowering your electricity bill are two entirely different fights. Environmental consultant Arif Gasilov notes that community opposition can block individual projects at the local level but rarely influences rate cases — the regulatory proceedings where electricity prices are actually set. Financial literacy expert Alex Beene sharpens the tension: grid-upgrade costs shift to residents while the economic benefits flow to corporations. Bills in PJM-heavy states are projected to stay elevated — potentially $15 to $20 per month higher in some areas, according to analysis from mgrid.org. Utility commission dockets are public record — finding your state’s open rate case and submitting written comment takes less than ten minutes, and that’s exactly where paying too much gets decided.
