Entergy Texas brings 1.2 GW gas plant online
Entergy Texas has commissioned the Orange County Advanced Power Station to meet rising industrial and population demand.
Key points
- The Orange County Advanced Power Station adds 1,215 MW of capacity.
- Mitsubishi Power supplied the facility's turbines and hydrogen-ready systems.
- Entergy Texas anticipates a 13 percent increase in electricity demand from 2024 to 2028.
What happened
Entergy Texas announced the commercial operation of the Orange County Advanced Power Station, adding 1,215 MW to the local grid, according to Power Engineering. Construction on the combined-cycle gas turbine facility began in the spring of 2023 with a projected cost of $1.2 billion.
Mitsubishi Power provided the plant's equipment, including two M501JAC gas turbines, a steam turbine, a heat recovery steam generator, and a control system. The facility is designed to support up to 100 percent hydrogen use in the future and can adjust output quickly to meet fluctuating demand.
Why it matters
Power Engineering reported that Texas experienced the highest population growth of any US state between 2024 and 2025. Industrial expansion across Southeast Texas is also contributing to higher energy consumption.
To address these trends, Entergy Texas projects a 13 percent increase in electricity demand across its service territory between 2024 and 2028. The utility plans to expand its total generation capacity by more than 2.4 GW by 2028, which includes two additional approved natural gas facilities known as Legend and Lone Star.
