Calpine / Constellation · Harris County · ERCOT

Deer Park Energy Center is a six-generator natural-gas combined-cycle cogeneration facility in Harris County, registered as EIA Plant ID 55464. EIA's May 2026 inventory lists 1,176 MW nameplate, 1,192 MW net summer, and 1,237 MW net winter capability across five combustion turbines and one steam turbine. The original trains entered service in 2003 and 2004; CTG6 entered service in 2014. ERCOT maps all six resources to the DDPEC resource node.

## Profile

- **ERCOT configuration:** Six thermal resources at resource node DDPEC: five gas turbines and one steam turbine.
- **Cogeneration role:** Calpine identifies Deer Park as a Houston Ship Channel cogeneration facility that supplies steam to the petrochemical industry.
- **Physical build:** Five 180 MW nameplate combustion turbines and one 276 MW nameplate steam turbine. EIA lists the gas turbines in 2003, 2004, and 2014 and the steam turbine in 2004.
- **Carbon capture:** Calpine, Shell, and project partners describe a FEED-stage system designed for roughly 5 million tonnes of net CO2 capture per year. No operating capture installation is claimed.
