Overview

The Gateway Generation Station is an 845-megawatt (MW), dual fuel, combined-cycle electric generating station located near Mt. Enterprise in Rusk County, Texas. Gateway consists of three General Electric (GE) Frame 7FA gas turbine generators, three heat recovery steam generators and one General Electric steam turbine.

The plant can dispatch power to multiple grids extending beyond ERCOT. Gateway interconnects with ERCOT through Houston Lighting & Power’s 345 kilovolt (kV) transmission system and with grids outside of ERCOT through Entergy’s 345 kV transmission system. This ability provides significant arbitrage opportunities in both power markets.

Shell Energy North America (US), L.P. (Shell) currently purchases the entire power output, incorporating the plant into its regional supply portfolio and selling the power on a merchant basis within the Electric Reliability Council of Texas (ERCOT) distribution grid and to markets in the Eastern Interconnected Grid, such as the Southwest Power Pool (SPP). Natural gas to fuel the plant, which can power up to 845,000 homes, is supplied by Shell. The plant also has the ability to generate power using fuel oil.
