Long Beach Generation LLC is a natural gas-fired power plant located in Long Beach, California, United States. With a capacity of 252 MW, it operates as a medium-scale facility within the US power generation sector, contributing to the state's energy mix. The plant is owned and operated by NRG El Segundo Operations Inc, a major independent power producer. The facility utilizes natural gas as its primary fuel, a cleaner-burning fossil fuel compared to coal. It operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its National Ambient Air Quality Standards (NAAQS), as well as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). These regulations govern emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and other pollutants, ensuring the plant meets modern environmental standards. As a gas-fired plant, Long Beach Generation LLC plays a key role in providing flexible and reliable power to the Los Angeles Basin, supporting grid stability and integrating renewable energy sources. Its location in an urban area underscores the importance of stringent emission controls to protect local air quality. The plant's operational status and capacity contribute to California's transition toward a lower-carbon electricity system.

The plant's gas-fired technology produces lower CO2 emissions per MWh compared to coal, but still contributes to greenhouse gas emissions. Its location near populated areas in Long Beach requires adherence to strict local and federal air quality standards. The facility's age and technology (likely combined cycle or simple cycle) influence its efficiency and emission profile. Regulatory oversight under the EPA's CAA ensures continuous monitoring and reduction of SOx, NOx, and particulate matter.
