Vistra to Install New Gas-Fired Units at Permian Basin Power Plant
LCG, September 30, 2025--Vistra Corp. announced yesterday that it will proceed with the next phase of its capital plan to support grid reliability in Texas. In 2024, Vistra identified over $1 billion worth of potential capital additions in generation capacity within the Texas ERCOT market by 2028 if market conditions were supportive. Now, with West Texas' growing power requirements, particularly the state's expanding oil and natural gas industries, Vistra reached a final investment decision and confirms it will build two new advanced natural gas-fired power units on-site at its Permian Basin Power Plant. The new units, together totaling 860 MW, will more than triple the site's current generating capacity from 325 MW to 1,185 MW and will increase Vistra's investment in new generating capacity in Texas to 3,100 MW since 2020.
"As the leading competitive generator in Texas, customers from residential to commercial and industrial are turning to Vistra to help them meet their energy needs," said the President and CEO of Vistra. "We recognize that energy is critical to powering this economic opportunity, and we expect Texas will play an outsized role. Based on our ongoing conversations with customers, we are affirming our multi-year plan to add more than 2,000 MW of new capacity in ERCOT between 2024 and 2028. Given Vistra's fleet, interconnections, and experience in improving, redeveloping, and building power plants, we are uniquely positioned to deliver solutions that provide reliable, affordable power to our residential customers as well as industries across Texas and the United States to ensure our economic competitiveness and national security."
Between 2020 and 2023, Vistra added approximately 1,000 MW of new generation capacity in Texas by increasing the generation output of its gas fleet and bringing new projects at Brightside, Emerald Grove, and DeCordova into commercial operation. In 2024, Vistra presented additional opportunities that could provide up to 2,000 MW of new generation capacity by 2028.
The Texas Governor stated, "Texas leads the nation in energy production, providing reliable and affordable power for Texans and the rest of the country. Vistra's bold investment in the Permian Basin will reinforce our state's electric grid, spur jobs, and drive regional economic growth for years to come. Together, we are powering Texas by supporting families, fueling businesses, and meeting the energy demands of our thriving state."
Vistra's announcement also summarized the significant progress on other Texas projects presented since the summer of 2024. First, over the past year, Vistra has invested in improvements that added over 400 MW of generation capacity across its existing Texas gas-fired facilities. Additional projects over the next year are expected to be completed, with the total of all upgrades forecast to be 500 MW of new capacity.
Second, the 200-MW Oak Hill Solar Project, located atop the site of the retired and reclaimed Oak Hill lignite mine, is nearly complete, and commercial operations are expected to commence in the fourth quarter of this year.
Third, Vistra will repower the coal-fired, Coleto Creek Power Plant that had been scheduled for retirement in 2027. By investing in plant upgrades and supporting pipeline expansion, the Vistra will create a dispatchable, natural gas plant on the property and repurpose the existing infrastructure. This will restore approximately 630 MW of generation to the grid, and the new gas-fueled capacity can serve Texans for decades to come, while retaining the important economic and tax benefits to the Goliad area.
"For decades, our company has been growing our generation fleet in competitive markets, responsibly planning and developing a pipeline of projects to meet America's growing need for power, while providing customers with the solutions that best meet their energy requirements. Vistra is committed to leveraging our diverse fleet of energy assets across markets to deliver solutions to help power our nation's economy and America's energy leadership," said the President and CEO of Vistra.
Upon completing these projects, Vistra will have invested nearly $2 billion to add approximately 3,100 MW of new generation capacity in Texas since 2020.
