Chattahoochee Energy Facility: 539.7 MW Gas Power Plant in Georgia, USA

Chattahoochee Energy Facility is a gas-fired power plant located in Georgia, United States, with a capacity of 539.7 MW. It is owned and operated by Oglethorpe Power Corporation, a generation and transmission cooperative serving electric membership corporations in Georgia. The facility plays a key role in meeting the state's power demand. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its National Ambient Air Quality Standards (NAAQS), the Acid Rain Program, and the Cross-State Air Pollution Rule (CSAPR). As a gas-fired facility, it benefits from lower emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) compared to coal plants, and its capacity places it in the medium-to-large scale for gas power generation in the region. Chattahoochee Energy Facility contributes to the reliability of Georgia's power grid, serving residential, commercial, and industrial customers. Its gas-fired technology provides flexible generation that can complement renewable sources. The facility's location in western Georgia supports local energy needs while adhering to federal environmental standards.

The facility's gas-fired technology results in lower CO2, SO2, and NOx emissions per MWh compared to coal, but still contributes to greenhouse gas emissions. Its location in a rural area of Georgia reduces direct exposure to densely populated centers, though regional air quality is subject to EPA NAAQS compliance. The plant's age and specific technology (e.g., combined cycle vs. Typical gas plants of this capacity often employ efficient combined-cycle systems.
