Overview
Moselle is a 510.5 MW gas-fired power plant in Mississippi, United States, operated by Cooperative Energy. It supplies electricity to the regional grid.
Moselle is a gas-fired power generation facility located in Mississippi, United States, with a capacity of 510.5 megawatts. The plant is owned and operated by Cooperative Energy, a generation and transmission cooperative serving member distribution systems across the state. As a gas power plant, it plays a key role in the region's energy mix, providing dispatchable power to complement renewable sources. 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). Gas-fired plants like Moselle typically use combined-cycle or simple-cycle technology, with modern facilities achieving higher efficiency and lower emissions compared to coal-fired units. The 510.5 MW capacity places it in the medium-to-large scale for gas plants in the United States. Moselle contributes to the reliability of the electric grid in Mississippi, supporting residential, commercial, and industrial customers. As a gas plant, it has a lower carbon footprint than coal but still emits CO2 and other pollutants. Its operational status ensures continued service, while regulatory compliance under EPA standards helps mitigate environmental impacts. The facility's location in the southeastern U.S. aligns with the region's growing demand for natural gas power generation.
Environmental context
The Moselle gas plant operates in Mississippi, a state with a humid subtropical climate. Gas-fired generation produces lower CO2 emissions per MWh than coal but still contributes to greenhouse gas emissions. The plant's proximity to populated areas may raise local air quality considerations, though modern gas plants typically employ controls for NOx and other pollutants. Regulatory oversight under the EPA's Clean Air Act ensures adherence to emission limits, and the facility's capacity of 510.5 MW places it within a scale where environmental management is a standard operational component.
