Intercession City Gas Power Plant | Duke Energy Florida | 1197 MW

Intercession City is a gas-fired power plant located in Florida, United States, with a capacity of 1197 MW. Owned by Duke Energy Florida LLC, the facility is operational and contributes to the regional electricity grid. The plant's scale places it among medium-to-large gas power plants in the country. As a gas power plant, Intercession City operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Cross-State Air Pollution Rule (CSAPR). Gas-fired plants generally have lower emissions of sulfur dioxide (SO2) and particulate matter compared to coal plants, but still require compliance with emission limits for nitrogen oxides (NOx) and other pollutants. The plant serves the power needs of the surrounding region, providing reliable electricity to residential, commercial, and industrial customers. Its location in central Florida places it within a growing population center, underscoring its importance for grid stability and local energy security.

The plant's gas fuel type results in lower CO2 emissions per MWh compared to coal, but it still contributes to greenhouse gas emissions. Its proximity to populated areas in central Florida necessitates careful management of NOx and other pollutants to comply with EPA air quality standards. The facility's capacity of 1197 MW indicates a significant environmental footprint, though modern gas turbines can achieve high efficiency and lower emissions.
