Lagoon Creek Gas Power Plant | Tennessee Valley Authority, USA

Lagoon Creek is a gas-fired power generation facility located in Tennessee, United States, with a capacity of 1,625 MW. It is owned and operated by the Tennessee Valley Authority (TVA), a federally owned corporation that provides electricity to millions in the region. The plant plays a significant role in the TVA's generation portfolio, contributing to the area's baseload and peak power needs. The plant operates on natural gas, a fuel that produces lower CO2 emissions compared to coal but still requires compliance with U.S. Environmental Protection Agency (EPA) regulations under the Clean Air Act, including New Source Performance Standards and the Acid Rain Program. The TVA's generation mix includes nuclear, coal, hydro, and gas, with gas providing flexibility to balance renewable sources. Lagoon Creek's environmental context involves its location in a region with moderate population density. Gas-fired plants like this one have a lower carbon footprint than coal but still emit NOx and CO2. The plant's capacity places it in the large-scale category for gas plants, and its operation supports grid reliability in the Tennessee Valley. The TVA's commitment to reducing emissions may influence future operational adjustments.

The Lagoon Creek plant uses natural gas, which emits less CO2 per MWh than coal but still contributes to greenhouse gas emissions. Its location in Tennessee, a state with varied air quality standards, means it operates under EPA regulations such as the Cross-State Air Pollution Rule (CSAPR) for NOx and SO2. The plant's size and fuel type place it in a moderate environmental risk category, with potential impacts on local air quality and climate.
