IRVING, Texas – Vistra completed its acquisition of Cogentrix Energy on Friday, adding 10 natural-gas power plants with approximately 5,500 megawatts of generating capacity and bringing its U.S. generation portfolio to nearly 50,000 megawatts.
In its Friday closing announcement, the company said the purchase from funds managed by Quantum Capital Group closed after all required regulatory approvals were received. Friday’s announcement marks a completed acquisition, rather than an agreement still waiting to close.
The acquired plants operate in three electricity markets: PJM, ISO New England and ERCOT. Vistra’s closing release lists 5,496 megawatts across the 10 facilities.
Plants span eight states
The largest additions are Patriot and Hamilton-Liberty in Pennsylvania, each listed at 881 megawatts. Other PJM assets include Lakewood in New Jersey at 286 megawatts, Rock Springs in Maryland at 740 megawatts, and Ocean in New Jersey at 375 megawatts.
In New England, the portfolio includes Newington in New Hampshire at 624 megawatts, Bridgeport in Connecticut at 558 megawatts, Tiverton in Rhode Island at 297 megawatts, and Rumford in Maine at 271 megawatts.
The Texas addition is Altura Cogeneration, listed at 583 megawatts in the ERCOT market. The facilities include combined-cycle plants, combustion turbines and cogeneration equipment, according to Vistra’s portfolio table.
Vistra said it acquired full ownership of all 10 plants, including the 25% interests in Patriot and Hamilton-Liberty that Cogentrix had not previously owned.
Another step in Vistra’s fleet expansion
The closing follows two other major additions to Vistra’s fleet. Its March 2024 acquisition of Energy Harbor added approximately 4,000 megawatts of nuclear generation. Its October 2025 purchase of seven natural-gas plants from Lotus Infrastructure Partners added more than 2,300 megawatts.
Chief Executive Jim Burke described the Cogentrix assets as a strategic fit for Vistra’s generation portfolio and said the company would combine the teams with a focus on safety and reliability.
The acquisition transfers existing generating assets. It does not mean that 5,500 megawatts of newly built power capacity began operating Friday, and Vistra’s closing announcement did not identify a purchase price.
Vistra, based in Irving, combines a retail-electricity business with a generation fleet that includes natural gas, nuclear, coal, solar and battery storage. The latest purchase expands that fleet’s natural-gas component across several major U.S. electricity markets.
