Nine Mile Point is a gas-fired power plant located in Louisiana, United States, with a capacity of 2,439.7 MW. This large-scale facility is owned and operated by Entergy Louisiana LLC and plays a significant role in the state's power generation mix. The plant operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Cross-State Air Pollution Rule (CSAPR). As a gas-fired plant, it benefits from lower emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compared to coal-fired plants, aligning with modern environmental standards. Nine Mile Point contributes to grid reliability and supports the energy needs of Louisiana's industrial and residential sectors. Its substantial capacity positions it as a key asset in Entergy's generation portfolio, helping to meet peak demand and integrate with renewable energy sources.
Environmental context
The plant's gas fuel type results in lower CO2 emissions per MWh compared to coal, but its large capacity means significant overall emissions. Located in Louisiana, it operates in a region with high humidity and proximity to the Mississippi River, which can influence cooling water use and thermal discharge. The facility's age and technology (likely combined cycle) affect its efficiency and environmental footprint.
