Constellation Finishes Brazos Valley Plant Sale to LS Power

what happened

Constellation Energy has finished selling its Brazos Valley Energy Center to LS Power, the company said in a statement carried by the Newsmetry API feed. The gas-fired combined-cycle plant, rated at 606 megawatts, sits near Houston and feeds into the ERCOT grid. The deal is another step toward meeting conditions tied to Constellation's takeover of Calpine, a transaction completed in early January 2026 that made Constellation the largest private-sector power producer globally.

Brazos Valley was first slated for sale in August 2026, a move mentioned in the company's second-quarter results. Separately, Constellation has agreed to transfer roughly 4.4 gigawatts of mostly gas-fired capacity in Delaware and Pennsylvania to LS Power. That group includes Bethlehem, York 1, York 2, Hay Road and Edge Moor, and the PJM-related portion is expected to close by year-end 2026, pending standard conditions. All of these divestitures stem from a commitment made to the Justice Department.

why it matters

For power markets in ERCOT and PJM, transfers like these can shift which owners control gas-fired supply in each region, and the closing shows how the Calpine-related conditions are being worked through.
