Vistra Closes Cogentrix Deal, Adding 10 Gas Plants

Prepared with input from partners

Vistra Corp. has completed its purchase of Cogentrix Energy from funds managed by Quantum Capital Group. The Irving, Texas, power company announced the closing on October 30. All required regulatory approvals were already in hand.

The 10 Cogentrix plants run on natural gas and total about 5,500 MW. Added to what Vistra already operates, they take the company to nearly 50,000 MW of capacity nationwide.

Where the plants are

The assets sit in three power regions: PJM, ISO New England and ERCOT. In PJM, Vistra gets Patriot and Hamilton-Liberty in Pennsylvania, 881 MW each, plus Lakewood in New Jersey at 286 MW, Rock Springs in Maryland at 740 MW and Ocean in New Jersey at 375 MW.

ISO New England accounts for four plants. Newington in New Hampshire has 624 MW, Bridgeport in Connecticut 558 MW, Tiverton in Rhode Island 297 MW and Rumford in Maine 271 MW. The single ERCOT asset is Altura Cogeneration in Texas, at 583 MW.

Most of the plants are combined-cycle gas turbines. Rock Springs and Ocean are combustion turbine plants, and Altura is a cogeneration facility. The portfolio totals 5,496 MW. Vistra now owns all of it outright, including the 25% interest in Patriot and Hamilton-Liberty that Cogentrix did not hold before.

The company has done this before. Its March 2024 Energy Harbor deal brought roughly 4,000 MW of nuclear capacity, and in October 2025 it took on seven gas plants from Lotus Infrastructure Partners, adding more than 2,300 MW.

"Natural gas plays a critical role in meeting our nation's growing energy needs, and the Cogentrix assets are a strong strategic fit for Vistra as we continue to grow our generation portfolio," said Jim Burke, Vistra's president and chief executive. He added that the company knows how to integrate generation assets into its fleet.
