AI Data Centers Drive Record Electricity Costs in U.S.

The rapid expansion of artificial intelligence data centers is driving record-high capacity market prices across the United States, particularly within the Washington D.C. metropolitan area. PJM Interconnection, the regional grid operator, identified data center load growth as the primary cause of these price spikes, which have added billions in projected power costs. In Washington D.C., residential electricity prices rose 94% between 2021 and 2026.

This surge in demand has sparked political and regulatory friction. Senator Elizabeth Warren called for higher taxes on data center companies, though a fact-check clarified that her claim regarding a 267% increase in residential bills actually referred to wholesale prices. In Virginia, Governor Abigail Spanberger's administration is urging regulators to ensure large-load customers pay for the transmission infrastructure they require to avoid subsidizing these costs through residential rates.

Local governments are also taking restrictive action. Prince George’s County, Maryland, implemented a two-year moratorium on new hyperscale data center development to evaluate the impact on water, land use, and energy resources. Meanwhile, Dominion Energy continues to invest billions in transmission projects to support the high demand in Northern Virginia and Loudoun County.
