New report shows Texas led nation in solar and battery growth in 2024

The winds of change in power generation are sweeping through Texas.

Texas outpaced all other states in various categories of power generation in 2024, according to a new report from Ember, an energy think tank. The report shows:

  • Texas contributed more (12 terawatt-hours) to the country’s 64 terawatt-hour rise in solar generation last year than any other state.
  • Texas installed more solar (7.4 gigawatts) and battery (3.9 gigawatt) capacity than any other state.
  • Texas installed more utility-scale battery capacity (3.9 gigawatts) than any other state.
  • Texas saw the second biggest increase (eight terawatt-hours) in natural gas generation in 2024. Only Virginia, at 10 terawatt-hours, ranked higher.
  • Texas ranked second among the states for the biggest drop in production of coal-fueled power (6.07 terawatt-hours), preceded only by Wyoming (6.3 terawatt-hours).

Overall, coal represented 14 percent of power generation in Texas last year, with the combination of wind and solar at 30 percent, according to the report. Across the U.S., says the report, wind and solar generated more electricity than coal for the first time. Coal generation made up just 15% of U.S. electricity generation in 2024.

“The shift away from coal has been primarily driven by market dynamics and availability of more cost-effective resources,” the report says. “The unit costs of wind and solar have reduced significantly and their quick installation makes them commercially attractive.”

Citing data like the figures published by Ember, Texas Gov. Greg Abbott champions Texas as the “Energy Capital of the World,” a title that Houston also claims.

“As Texas continues to experience unprecedented growth, we will remain a leader in energy while also bolstering the Texas grid to meet the growing demands of our great state,” Abbott said in 2024.

Colorado-based energy storage company SMT Energy and North Carolina-based software company FlexGen have begun operations of Houston IV, a 160-megawatt utility-scale battery storage facility that aims to support the ERCOT grid.

The companies delivered the project in just six weeks, according to a news release. Mississippi-based Irby Construction Company served as the engineering, procurement, and construction (EPC) partner, and CenterPoint Energy will serve as the interconnecting utility.

“FlexGen’s distinctive combination of software automation, our remote operations center, and on-the-ground field expertise all work together to accelerate battery deployment,” Jason Rislov, SVP of operations at FlexGen, said in the release. “What used to take 25-plus weeks took us six. That time saved translates directly into giving the grid and consumers what they need most right now: a more reliable, resilient energy system.”

Houston IV is one of more than 12 projects that SMT and FlexGen have built to connect to ERCOT, according to Energy Storage News.

“Bringing a 160-MW battery storage facility online in just six weeks required disciplined planning, seamless coordination, and an unwavering focus on safety and quality,” Shaun Coleman, project manager at Irby Construction, said in a news release. “The SMT Energy, FlexGen, and Irby Construction teams coordinated engineering, procurement, and construction to keep every workstream aligned, identify challenges early, and maintain safety and quality at an accelerated pace. That integration is critical, not only to delivering projects quickly, but also to ensuring battery storage facilities perform reliably over the long term.”

Houston IV is expected to store and provide enough electricity to power 8,800 homes in Texas annually. In March, SMT Energy secured $135 million in funding for the project from Macquarie and KeyBanc Capital Markets as joint lead arrangers. SMT and FlexGen broke ground to signal the start of the process in May.

In 2023, SMT Energy and joint venture partner SUSI Partners also announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.
