Much of the country’s growth in utility-scale solar power generation will happen in the grid operated by the Electric Reliability Council of Texas (ERCOT), according to a new forecast.

The U.S. Energy Information Administration (EIA) predicts that solar power supplied to the ERCOT grid will jump from 56 billion kilowatt-hours in 2025 to 106 billion kilowatt-hours by the end of 2027. That would be an increase of 89 percent.

In tandem with the rapid embrace of solar power, EIA anticipates battery storage capacity for ERCOT will expand from 15 gigawatts in 2025 to 37 gigawatts by the end of 2027, or 147 percent.

EIA expects utility-scale solar to be the country’s fastest-growing source of power generation from 2025 to 2027. It anticipates that this source will climb from 290 billion kilowatt-hours last year to 424 billion kilowatt-hours next year, or 46 percent.

Based on EIA’s projections, ERCOT’s territory would account for one-fourth of the country’s utility-scale solar power generation by the end of next year.

“Solar power and energy storage are the fastest-growing grid technologies in Texas, and can be deployed more quickly than any other generation resource,” according to the Texas Solar + Storage Association. “In the wholesale market, solar and storage are increasing grid reliability, delivering consumer affordability, and driving tax revenue and income streams into rural Texas.”
