Vistra’s Plan to Support Reliability
Vistra is Texas’ leading power generator with a 140-year track record of powering a better way forward. Between 2020 and 2023, the company added over 1,000 MW of new generation capacity in Texas by increasing the generation output of its fleet and bringing new projects at Brightside, Emerald Grove, and DeCordova into commercial operation.
In 2024, Vistra identified more than $1 billion worth of potential investments to add generation capacity within ERCOT by 2028. The company’s plan focuses on solutions that could quickly add more than 2,000 MW of new generation capacity—enough electricity to power approximately 1 million homes—to the grid by 2028.
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.
Vistra is continually evaluating how its 2024 framework can be implemented, which will help:
- Ensure Power for the People of Texas
- Vistra’s responsible plan adds a surplus of new dispatchable generation incrementally through 2028.
- Support Texas’ Generation Growth and Enhance Grid Reliability
- Certainty of demand from private-sector investments in Texas pulls forward the construction of new dispatchable gas generation.
- Contribute to the Texas Miracle with Balanced and Predictable Electric Demand Growth
- Competitive solutions are the best way to meet the increase in demands for electricity, which will benefit all of the state’s residents, businesses, and industries.
- Create Jobs, Generate Taxes, and Spur Economic Development
- Affordable, reliable electricity is the essential ingredient for the continued growth and attraction of businesses, industries, and manufacturers.
Vistra’s Investments In Reliability: 3,100+ MW by 2028
Operating
470 MW
Across its existing fleet of natural gas plants, Vistra has been upgrading generating equipment to produce more electricity from the same sites, a practice known in the industry as an uprate. These upgrades have added approximately 470 MW of dispatchable capacity to the ERCOT grid, with more planned. The new generation arrives in months instead of the years it takes to permit, build and connect a new power plant.
Operating
200 MW
The 200‑MW Oak Hill solar project, built on the reclaimed site of the former Oak Hill lignite mine, was completed and energized in 2025. A second 200-megawatt phase, Oak Hill 2, is already under construction to meet evolving needs.
Under Construction
~630 MW
Coleto Creek was scheduled for retirement in 2027. Vistra is repowering it instead, converting the plant from coal to natural gas and repurposing the considerable existing infrastructure on the property. The conversion is underway, with completion expected by the end of 2026, and will restore approximately 630 MW of dispatchable generation that can serve Texans for decades to come, while retaining the important economic and tax benefits to the Goliad area.
Under Construction
860 MW
Two advanced natural gas units are under construction at the Permian Basin Power Plant near Monahans, adding 860 MW to the ERCOT grid. Foundation work is substantially complete, major equipment is being installed, and the project is on schedule for completion by 2028.
