Signal AI Data Center Boom & Power Grid Strain 2026

Summary

Electricity consumption growth rates are rising across the United States, driven in part by a boom in hyperscale data center development. Although the long-term market outlook remains uncertain, Lawrence Berkeley National Laboratory projects data center demand growing from 176 terawatt hours in 2023, about 4.4% of total US electricity consumption, to between 325 and 580 terawatt hours, or 6.7 to 12.0%, by 2028. This trend is reinforced by estimates that a single AI task can consume up to 1,000 times the electricity of a conventional web search. Goldman Sachs projects data center power demand rising 165% by 2030 versus 2023 levels, reaching 92 gigawatts by 2027. EPRI expects data centers' share of Virginia's electricity consumption to climb from 26% in 2023 to between 41% and 59% by 2030, with planned capital expenditure through 2030 amounting to at least 1.4 trillion dollars. In some parts of the country, AI-driven energy demand is already outpacing available capacity, pushing companies to delay projects or contract power directly from private producers.
