Ouachita is a gas-fired power plant located in the United States, with a capacity of 903.9 MW. It is owned and operated by Entergy Louisiana LLC, a major utility in the region. The plant plays a key role in meeting the electricity demands of Louisiana and surrounding areas. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). As a gas-fired facility, it benefits from lower emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compared to coal-fired plants, though it still contributes to carbon dioxide (CO2) emissions. Ouachita's capacity of 903.9 MW places it in the large-scale category for gas power plants. Its operational status ensures a reliable power supply to the grid, supporting residential, commercial, and industrial users. The plant's location in Louisiana, a state with significant energy infrastructure, underscores its importance in the regional energy mix.
Environmental context
The plant's gas-fired technology results in lower SOx and NOx emissions compared to coal, but it still emits CO2. Its location in Louisiana, a state with a mix of industrial and natural areas, means emissions may affect local air quality. The plant's capacity and age influence its environmental footprint, with modern gas plants typically achieving higher efficiency and lower emissions per MWh.
