US Data Center Power Demand for 2025 Splits 31 GW to 64.4 GW Across Analyst Trackers
Three widely cited analyst trackers each published a current-year figure for US data center power demand in 2025, and the values diverge by 33.4 gigawatts -- from 31 GW (Goldman Sachs Research) to 64.4 GW (S&P Global's 451 Research), a spread of roughly 108% on the low-end estimate. Running these figures through UVRN's Delta Engine surfaces the disagreement rather than forcing a single consensus number. The likely driver is inconsistent scope: Goldman's figure is a forward-looking demand forecast, BloombergNEF's is described as capacity 'in operation today,' and S&P Global's is measured grid power actually supplied to hyperscale, leased, and crypto-mining facilities.
Findings
- Goldman Sachs Research pegs 2025 US data center power demand at 31 GW, rising to 41 GW in 2026 and 66 GW in 2027.
- BloombergNEF's December 2025 report puts current US data center power draw at 40 GW "in operation today," en route to 106 GW by 2035 -- a 36% upward revision from its April 2025 outlook.
- S&P Global's 451 Research measured 2025 US grid power supplied to data centers at 64.4 GW, up 25% year-over-year and exceeding its own June 2025 forecast of 58 GW by year-end.
- The three trackers' 2025 figures span 31 GW to 64.4 GW -- a 33.4 GW gap, roughly 108% of the low-end estimate -- despite all three nominally measuring the same metric for the same calendar year.
