US Electricity Demand Hits Record Highs as Data Centers Drive Growth
U.S. electricity demand is on pace for record highs in 2026 and 2027, ending nearly a decade of flat power consumption, OilPrice.com reports. Total U.S. electricity supply hit 2,234 terawatt hours in the first half of 2026, up 3% year over year, according to data from clean energy think tank Ember cited in the report. The Energy Information Administration’s latest outlook projects total consumption will rise from a record 4,195 billion kilowatt-hours in 2025 to 4,269 billion kWh this year and 4,399 billion kWh in 2027. Data centers are the main driver: EIA called data center load “the dominant driver of long-term U.S. electricity growth,” and Goldman Sachs Commodities Research forecasts U.S. data center power demand will more than double to 66 gigawatts in 2027 from 31 GW in 2025. Natural gas remains the backbone of the grid at roughly 40% of generation, while solar and storage accounted for 91% of new capacity added in the first quarter of 2026, according to SEIA and Wood Mackenzie, with Texas the fastest-growing solar market in the country.
What It Means for Subcontractors
- Gas-fired generation, transmission, and substation work tied to data center buildouts should keep expanding as EIA projects consumption climbing through 2027, meaning E&I, civil, and mechanical trades tied to utility-scale interconnection and switchyard projects have a multiyear runway of bid packages ahead.
- Solar and battery storage EPC and O&M subcontractors have a strong near-term pipeline in Texas and other certain Republican-leaning states, which SEIA says accounted for 74% of all solar capacity installed in Q1 2026, meaning electrical and civil crews should watch for utility-scale solar-plus-storage packages concentrated in those markets.
- Utilities facing tight summer peaks as data centers push toward 8.5% of U.S. peak demand by 2027 (per Goldman Sachs) will likely accelerate grid-hardening and capacity upgrade contracts, so subcontractors in substation construction, HDD for underground feeders, and transmission line work should track regional utility capital plans for near-term RFPs.
