Irving, Texas-based Vistra Corp.

The transaction, which closed on Oct. 30, 2026, includes 10 modern facilities located in key competitive power markets, including PJM, ISO New England (ISO-NE), and ERCOT. The closing follows the receipt of all necessary regulatory approvals and brings Vistra's total U.S. generation capacity to nearly 50,000 MW.
The acquired portfolio consists of efficient combined-cycle combustion turbine (CCGT) and cogeneration assets. In the PJM market, Vistra now owns the Patriot and Hamilton-Liberty plants in Pennsylvania, each with 881 MW of capacity, as well as the Lakewood and Ocean plants in New Jersey and the Rock Springs facility in Maryland. The acquisition also includes five plants in the ISO-NE region: Newington in New Hampshire, Bridgeport in Connecticut, Tiverton in Rhode Island, and Rumford in Maine. In Texas, the company added the 583 MW Altura Cogeneration facility within the ERCOT market. Vistra confirmed it has acquired 100% ownership in all these plants, including minority interests in the Patriot and Hamilton-Liberty facilities not previously held by Cogentrix.
Jim Burke, president and chief executive officer of Vistra, stated that the Cogentrix assets are intended to help meet growing energy needs and represent a strategic fit for the company's expanding generation fleet. The company noted that this transaction follows a series of recent expansions, including the March 2024 acquisition of Energy Harbor, which added 4,000 MW of nuclear capacity, and the October 2025 acquisition of seven natural gas plants from Lotus Infrastructure Partners, which added 2,300 MW.
