How much electricity do AI data centers use, and who pays for it?
Data centers are projected to use 11.8% of U.S. electricity by 2030 in LBNL’s reference case (range 9.5% to 15.3%, 2026), up from about 4.4% in 2023. Utility tariffs and cost-allocation orders, not a data center’s own bill, decide how much of that buildout reaches households. Grade: AI-contributing.

How does AI demand affect this market?
Large, flat loads require generation, transmission and distribution investment. Tariffs, utility regulation, fuel prices and dedicated-upgrade charges determine how those costs reach households.
Who pays, and who benefits?
Data centers pay energy and connection charges directly. Regulatory cost allocation assigns shared system costs and fixed-cost revenue across customer classes.
What limits supply?
The main challenge is how quickly new generation, transmission and substations can be built, connections can be studied and customer protections can be put in place.
What the evidence cannot show
National electricity prices do not show what bills would have been without AI. EIA found that natural-gas prices drove much of the 2025 increase in wholesale power prices.
What would change the grade
Any grade about household bills must be calculated utility by utility from approved rates and cost-allocation orders.
