Overview
Lake Catherine is a 552.5 MW gas power plant in Arkansas, USA, owned by Entergy Arkansas LLC. It provides electricity to the regional grid under US EPA regulatory oversight.
Lake Catherine is a gas-fired power generation facility located in Arkansas, United States, with a capacity of 552.5 megawatts. Owned by Entergy Arkansas LLC, the plant operates as a key component of the state's energy infrastructure, supplying electricity to residential, commercial, and industrial customers. The facility is classified as a medium-scale gas power plant within the US power generation sector. 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 facility, it benefits from lower emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compared to coal plants, aligning with modern environmental standards. The technology likely employs combined cycle or simple cycle gas turbines, typical for plants of this size and fuel type. Lake Catherine plays a significant role in meeting regional electricity demand, particularly during peak periods. Its gas-fueled operation provides flexibility and reliability to the grid, supporting the integration of renewable energy sources. The plant's location in Arkansas contributes to the state's energy mix, which is transitioning toward cleaner generation while maintaining baseload capacity.
Environmental context
As a gas-fired power plant, Lake Catherine produces lower CO2 emissions per megawatt-hour compared to coal plants, but still contributes to greenhouse gas emissions. Its proximity to populated areas in Arkansas may raise local air quality considerations, though modern gas turbines are equipped with emission controls to meet EPA standards. The plant's fuel type and capacity suggest a moderate environmental footprint within the sector.
