Hyperscale data centers in the U.S. will need 22% more grid-based power by the end of the year, according to a new report from S&P Global. That’s a 11.3 GW rise, up to a total of 61.8 GW.
By 2030, they will need almost three times as much (or 134.4GW), according to forecasting by 451 Research.
These numbers do not include enterprise-owned data centers outside of hyperscalers like Microsoft, Amazon, and Google.
Here’s a breakdown of data center electricity demand by key region:
- Virginia: 12.1GW in 2025, up from 9.3GW in 2024
- Texas: 9.7GW in 2025, up from just under 8GW in 2024
- Oregon: 4GW in 2025, up from 3.5GW in 2024
- Ohio: 13 GW in 2025, down from 30 GW in 2024. This is one of the few regions seeing decreasing demand, largely due to new data center tariffs. These require data centers to partially pay for energy requests, even if they ultimately don’t need the electricity.
