Overview
John Sevier is a 996.9 MW gas power plant in Tennessee, USA, operated by the Tennessee Valley Authority. It provides electricity to the regional grid.
John Sevier is a gas-fired power plant located in Tennessee, United States, with a capacity of 996.9 MW. It is owned and operated by the Tennessee Valley Authority (TVA), a major federal utility serving the southeastern US. The plant plays a key role in meeting regional electricity demand. The facility operates on natural gas, a fuel that produces lower CO2 emissions compared to coal but still contributes to greenhouse gas emissions. As a gas plant, it likely uses combined-cycle or simple-cycle technology, though specific configuration is not detailed. The plant's capacity places it in the medium-to-large scale for gas power generation in the US. John Sevier is subject to US EPA regulations under the Clean Air Act, including New Source Performance Standards and emission limits for NOx and SO2. Its operational status and TVA's management ensure compliance with federal and state environmental standards. The plant supports grid reliability in the Tennessee Valley region.
Environmental context
The plant's gas fuel type results in lower SOx and particulate emissions compared to coal, but NOx and CO2 emissions remain significant. Its location in Tennessee, a state with varied air quality standards, means it operates under EPA's Cross-State Air Pollution Rule (CSAPR) and regional haze regulations. Proximity to populated areas could influence local air quality impacts.
