# Vistra One of the largest competitive power generators in the United States, headquartered in Irving, TX and traded on the NYSE under ticker VST. Vistra's fleet totals approximately 44 GW of owned capacity — rising to roughly 50 GW once the pending Cogentrix acquisition closes — spanning natural gas (~27 GW), nuclear (~6.5 GW), coal (~8.7 GW), solar, and battery storage. CEO Jim Burke has steered the company into the nuclear-AI power lane, making Vistra [[Constellation Energy]]'s primary rival for long-term corporate nuclear offtake contracts. ## Nuclear Fleet Vistra completed its $3.43B acquisition of Energy Harbor in March 2024, adding approximately 4,000 MW of 24/7 nuclear generation and roughly one million retail electricity customers. The deal brought three reactor complexes into the portfolio: Davis-Besse and Perry in Ohio, and Beaver Valley in Pennsylvania. The combined fleet is the second-largest competitive nuclear fleet in the country, behind only [[Constellation Energy]]. ## Meta Nuclear PPA In January 2026, Vistra signed 20-year power purchase agreements with [[Meta]] covering 2,609 MW of carbon-free nuclear power and capacity from its PJM plants. The deal includes 2,176 MW of existing generation plus 433 MW of planned uprates — the largest nuclear uprates supported by a corporate customer in US history. Initial delivery begins late 2026, with full operating capacity by end of 2027 and uprate capacity phasing in through 2034. ## Gas Expansion Vistra acquired Cogentrix Energy (10 modern natural gas facilities, ~5,500 MW) for approximately $4B in a deal announced December 2025, expected to close mid-to-late 2026. This followed a $1.9B acquisition of seven gas-fired plants (~2,600 MW) from Lotus Infrastructure Partners in May 2025. The gas buildout positions Vistra as a dispatchable backstop for intermittent renewables and AI load growth. ## Texas Operations Subsidiary Luminant operates Vistra's generation assets in the ERCOT deregulated market, where the company maintains a diverse fleet of gas, coal, solar, and battery storage facilities. ERCOT is the grid that hosts both the [[Stargate Project]] and Lancium campuses, making Vistra a power supplier in the same market where hyperscale AI buildout is concentrated. ## KB Relevance Vistra matters to the vault as [[Constellation Energy]]'s main competitor in the nuclear-for-AI market. The [[Meta]] PPA, the Energy Harbor nuclear acquisition, and the Cogentrix gas expansion together illustrate how legacy power generators are repositioning around [[Artificial Intelligence]] demand. Its Texas footprint via Luminant ties it to ERCOT, [[Stargate Project]], and [[The Quest for 90 Gigawatts]]. ## See Also - [[Constellation Energy]] - [[Meta]] - [[Amazon]] - [[The Quest for 90 Gigawatts]] - [[Stargate Project]] - [[Energy Sector]]
