Ingleside Cogeneration
Ingleside Cogeneration LP · San Patricio County · ERCOT
Ingleside Cogeneration is a three-generator natural-gas combined-cycle cogeneration plant in San Patricio County, Texas. EIA's May 2026 inventory reports 517 MW nameplate, 460 MW net summer, and 508 MW net winter capability across two combustion turbines and one steam turbine, all operating since July 1999. Occidental and Conoco developed the facility to supply power and steam to adjacent industrial operations, but current public registry data identifies Ingleside Cogeneration LP as the plant entity.
