Utility-scale solar electricity is on track to exceed coal-fired output within the ERCOT grid this year, driven by ongoing large-scale capacity expansions that are transforming Texas’s energy landscape.
According to the latest Energy Information Administration Short-Term Energy Outlook, a fundamental shift is underway in the Electric Reliability Council of Texas market. Solar generation is projected to hit 78,000 GWh in 2026, outpacing the 60,000 GWh expected from coal.
Recently, combined solar and wind output reached a record 17% of total U.S. power generation, and this trend is accelerating. By the close of 2026, solar alone is predicted to supply 12% of Texas’s electricity, while coal’s portion is set to shrink to 13%.
This generation growth is fueled by a sharp rise in physical infrastructure, with Texas accounting for roughly 40% of all new U.S. solar capacity additions in 2026. Developers are planning to bring 14 GW of new utility-scale solar online in Texas as part of a national surge of 86 GW. Notable among these is the 837 MW Tehuacana Creek 1 Solar and BESS facility, expected to be the largest single photovoltaic installation to begin operations in the country this year.
Texas remains a key driver of the domestic energy transition, hosting 12.9 GW—or 53%—of the 24 GW of utility-scale battery storage slated for the U.S. grid in 2026. This battery expansion is essential for maintaining grid stability as renewable energy penetration increases. Total U.S. battery capacity is now forecast to reach 67 GW by early 2027, a substantial rise from the 15 GW added in 2025.
The national picture mirrors Texas’s transformation, with solar and wind combined expected to surpass 20% of total U.S. electricity generation by early 2027. Beyond solar, wind additions are projected to double to 11.8 GW, aided by the completion of major offshore projects such as the 800 MW Vineyard Wind 1. While solar and storage dominate the 2026 pipeline, small-scale solar is also anticipated to add 8 GW of new capacity, further broadening the decentralized grid.
