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:

  1. Ensure Power for the People of Texas
    • Vistra’s responsible plan adds a surplus of new dispatchable generation incrementally through 2028.
  2. 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. 
  3. 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.
  4. 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

Complete: 400+ MW

Over the past two years, Vistra has invested in technologies and upgrades that added more than 400 MW of generation capacity across its existing Texas gas-fueled power plant fleet. These improvements have been completed and are generating power for the people of Texas. The company is working on additional projects in 2026 and expects that when finished, all of the upgrades will have added a total of 500 MW of additional capacity.

Nearing Completion: 200 MW

Construction is nearly complete on the 200-MW Oak Hill solar project, located atop the site of the retired and reclaimed Oak Hill lignite mine. Commercial operations of this new facility are expected to commence in the fourth quarter of 2025.

On Track: ~630 MW

The company will repower the Coleto Creek Power Plant that was scheduled for retirement in 2027. By investing in plant upgrades and supporting pipeline expansion, the company will create a dispatchable gas plant on the property and repurpose the considerable 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. 

Under Development: 860 MW

Two advanced simple-cycle natural gas-fueled power units are under development at the site of the Permian Basin Power Plant to help meet the growing needs of West Texas’ oil and natural gas industries and the state. In total, the units will add 860 MW to the grid. Initial development activities are underway to ensure the plant’s expanded operations can begin operating by 2028. The company has reached a final investment decision and confirms it will build the units.
