The Sim Gideon Combined Cycle project is a proposed 880 MW gas-fired combined-cycle generation project located in Bastrop County, Texas. Developed by LCRA, the project is interconnected within the ERCOT region under queue ID ERCOT-30INR0051. It entered the interconnection queue on June 19, 2025, with a proposed commercial operation date of December 15, 2030, and an Interconnection Agreement (IA) date of December 19, 2025. The point of interconnection is designated as (#7310) SIM GIDEON 138 kV.
This development project is linked to the existing Sim Gideon operating plant (EIA plant ID 3601). The project has been mentioned in recent news, with five articles covering topics related to the grid and industry.
