Rapid growth in artificial-intelligence data centers is putting pressure on U.S. power markets, with dense server racks and long grid-connection timelines raising reliability risks in several regions.

Next-generation AI server racks expected in 2027 could require 600 kilowatts of power and contain 576 graphics processing units, enough electricity to supply about 500 U.S. homes. That is 50 times the power used by comparable central processing unit racks five years earlier.

U.S. data-center power demand is projected to rise from 31 gigawatts in 2025 to 41 gigawatts in 2026 and 66 gigawatts in 2027. A separate forecast puts demand at about 108 gigawatts by 2030, up from an earlier estimate of about 83 gigawatts.

Data centers are projected to account for 8.5% of total U.S. peak-summer electricity demand in 2027, compared with 4.1% in 2025.

The Mid-Atlantic, Mid-Continent and Northwest markets face elevated reliability risks because planned generation additions may not match incoming data-center demand. The Mid-Atlantic is expected to remain the largest U.S. data-center power market through 2030, while the Mid-Continent market is projected to represent about 16% of U.S. demand and Texas about 14%.

Grid connections for new U.S. data centers can take as long as seven years. Projects representing roughly 40% to 50% of planned data-center capacity may miss their expected startup dates over the next two years.

“The binding constraint has migrated away from megawatts and towards what I think of as all the Ts,” Allison Nathan said.

Those constraints include transmission construction, transformers, permitting, equipment availability and community opposition. Texas and Georgia may face less pressure because additional generation is already planned.

AI systems use large numbers of GPUs operating together in tightly integrated racks, increasing demand for new facilities, transmission capacity, transformers and workers. The warning describes a developing infrastructure risk rather than a confirmed blackout event.
