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.”

Since 2023, wind and solar power have been the fastest-growing sources of electricity for the Electric Reliability Council of Texas (ERCOT) and increasingly are meeting stepped-up demand, according to a new report from the U.S. Energy Information Administration (EIA).

The report says utility-scale solar generated 50 percent more electricity for ERCOT in the first nine months this year compared with the same period in 2024. Meanwhile, electricity generated by wind power rose 4 percent in the first nine months of this year versus the same period in 2024.

Together, wind and solar supplied 36 percent of ERCOT’s electricity in the first nine months of 2025.

Heavier reliance on wind and solar power comes amid greater demand for ERCOT electricity. In the first nine months of 2025, ERCOT recorded the fastest growth in electricity demand (5 percent) among U.S. power grids compared with the same period last year, according to the report.

“ERCOT’s electricity demand is forecast to grow faster than that of any other grid operator in the United States through at least 2026,” the report says.

EIA forecasts demand for ERCOT electricity will climb 14 percent in the first nine months of 2026 compared with the same period this year. This anticipated jump coincides with a number of large data centers and cryptocurrency mining facilities coming online next year.

The ERCOT grid covers about 90 percent of Texas’ electrical load.

CenterPoint gets $50M DOE grant to improve Houston power grid

grid grant

A $50 million federal grant will help Houston-based CenterPoint Energy strengthen Houston’s power grid.

The U.S. Department of Energy (DOE) grant will support power substation upgrades in the Houston area.

“Our mission is to build the most resilient coastal grid in the nation for the 2.9 million customers we proudly serve in the greater Houston area … [The grant] will directly fund industry-leading technology improvements that are expected to strengthen resiliency, reliability, and meet the growing energy needs of our region,” Jason Ryan, CenterPoint Energy’s executive vice president for regulatory services and government affairs, said in a release.

CenterPoint says the project will make it one of the first U.S. utilities to install Siemens Energy’s grid-stabilizing technology.

The project will create more than 500 construction and installation jobs, CenterPoint says.

“Generations of CenterPoint customers and families in the region will benefit from the advanced technology this grant is funding,” said Kathleen Jackson, a member of the Public Utility Commission of Texas. “And any time companies make improvements like this to their systems, the long-term impact is making the entire grid stronger for Texans.”

The $176.7 million substation project is part of CenterPoint’s Greater Houston Resiliency Initiative, which launched in 2024.

So far, the initiative has:

Installed nearly 82,400 storm-resilient poles and equipment
Trimmed and cleared more than 13,700 miles of trees and vegetation near power lines
Added nearly 820 grid automation and intelligence devices
Put more than 880 miles of power lines underground

The initiative kicked off three years after Winter Storm Uri. CenterPoint received harsh criticism for what customers complained was the utility’s slow response to the 2021 storm. Uri caused a massive power outage and at least 246 deaths across Texas.

CenterPoint blamed the Electric Reliability Council of Texas (ERCOT), which operates the power grid for most Texans, for not supplying the utility with enough electricity during and after the storm.

EnergyTech Cypher names 7 startup winners from Pilotathon pitch event
