Utility-scale solar, wind and battery storage are projected to add more than 80GW of new generating capacity in the US by February 2027.
Renewable energy’s share of total utility-scale capacity is expected to rise from 33.4% to 36.6% over the period, the US Energy Information Administration (‘EIA’) said.
Solar will add 42,628.6MW while wind will grow by 14,507.4MW including 4,155.0MW of offshore capacity, the agency added.
The combined capacity growth of renewables of 57,452.7MW is almost 75% higher than the 32,988.9MW added in the previous 12 months.
By contrast, no new nuclear capacity is forecast while fossil fuel capacity is projected to decline by 4,903.2MW.
Utility-scale battery storage is expected to increase by 51.4% from 44,630.7MW to 67,549.6MW.
Including estimated small-scale solar additions, renewables’ share of installed capacity could reach 39.7% while natural gas falls from 40.0% to 38.3%.
Electricity generation from renewables rose by 10.8% in January and February 2026, accounting for 26.0% of total output compared with 23.6% a year earlier.
“Notwithstanding all of the policy obstacles thrown up by the Trump Administration during the last year, renewables raced ahead in 2025,” said Ken Bossong, executive director of the SUN DAY Campaign.
“Now they are poised to really press the pedal to the metal in 2026 and beyond.”
