How AI Data Centers Are Driving Up Electricity Prices for US Consumers

The boom in AI data centers across the United States is having a direct impact on ordinary households’ electricity bills. That’s what current data from the capacity auctions run by grid operator PJM Interconnection shows — PJM serves 13 U.S. states plus Washington, D.C., supplying power to roughly 67 million people.
Billions in Added Costs Driven by AI Demand
PJM recently published the results of an auction to procure power capacity for the period from June 2028 to May 2029. Of the $16.4 billion in total capacity market charges resulting from that auction, about $6.3 billion is attributable to demand from data centers, according to Monitoring Analytics, PJM’s independent market monitor.
Across the last four PJM auctions, data center demand has added a combined $29.4 billion in costs, according to Monitoring Analytics. That figure represents roughly 46 percent of total capacity charges over that period — even though data centers currently account for only about 4 percent of total U.S. electricity consumption.
Monitoring Analytics President Joseph Bowring has argued that data center demand should be separated from the standard capacity market and procured instead through a dedicated auction of its own. According to Bowring, that would be the only way to ensure data centers pay for their own capacity rather than shifting those costs onto other customers.
Uneven Impact Across States
How much of this added cost actually reaches consumers depends heavily on the state. Regions with a high concentration of data centers are hit hardest:
- Illinois: about 23.85¢/kWh, up roughly 28% year-over-year — one of the steepest increases in PJM territory
- Virginia: about 17.61¢/kWh, up roughly 15.4% — home to “Data Center Alley,” one of the densest concentrations of data centers in the world
- Georgia: about 15.84¢/kWh, up roughly 5.7% — where public frustration over rising bills led to the ouster of two utility regulators in 2025
- Texas: about 16.44¢/kWh, up roughly 5.9% — grid operator ERCOT has warned that additional AI-driven load could further strain the grid
By comparison, Hawaii has the highest rate nationwide at roughly 52¢/kWh (+26.7%), but that increase is driven primarily by fuel costs and the isolation of its island grid, not by data centers.
Voluntary Pledges Without Legal Force
President Trump’s so-called “Ratepayer Protection Pledge” calls on tech companies to cover their own energy costs, and firms including Microsoft and Anthropic have made similar voluntary commitments. The catch: these pledges carry no legal weight and include no enforcement mechanisms.
According to policy tracker MultiState, 27 U.S. states are currently 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.
Observers also note that local opposition to individual data center projects can block specific developments, but has little influence on the actual rate cases — the regulatory proceedings where electricity prices are set. Critics see this as a structural problem: the costs of grid expansion are spread across the general public, while the economic benefits flow largely to the companies building the data centers.
No Quick Relief in Sight
PJM also said it was unable to procure enough capacity in the latest auction to meet its reliability target — a problem that also arose in the previous auction covering 2027–2028. The grid operator has asked federal regulators for permission to hold a special “Backstop Procurement” to secure additional capacity.
PJM President and CEO David Mills said in a written statement that electricity demand is currently growing faster than supply, and that the company is working with government and industry to restore that balance. The statement did not explicitly mention data centers, though PJM has previously identified them as the fastest-growing driver of electricity demand.
Analysts and consumer advocates, meanwhile, don’t expect relief anytime soon: in regions heavily served by PJM, monthly electricity bills could run $15 to $20 higher than before in the coming years, according to market observers — with meaningful improvement unlikely before the 2030s.
