Data centers are expected to consume one-fifth of U.S. electricity by 2035, four times today's share, according to a new BloombergNEF report. The surge in AI compute will push data center capacity to nearly 200 gigawatts over the next decade, with almost half devoted to training and inference, mostly concentrated in the U.S., which will host 64% of AI chips by power demand in 2033. The new 2035 electricity demand estimate is 83% higher than BloombergNEF's December forecast, while EPRI has more than doubled its 2024 estimate and S&P's forecast rose by more than a third between October and April. The PJM Interconnection, spanning Virginia to Illinois, will see 34% of its electricity go to data centers, and ERCOT in Texas will devote 22% of its generating capacity, even as PJM struggles with connection requests and electricity prices have risen 76% over the past year. Globally, aggressive AI adoption could create 1,935 terawatt-hours of new electricity demand by 2033, nearly as much as India uses annually.
