Coughlin Power Station: Gas Power Plant in Louisiana, USA

Coughlin Power Station is a gas-fired power generation facility located in Louisiana, United States, with a capacity of 922.8 MW. The plant is owned and operated by Cleco Power LLC and is currently operational, serving the regional electricity grid. 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 power plant, it likely uses combined cycle or simple cycle technology, typical for modern gas plants in the US. The plant's capacity places it in the large-scale category for gas-fired generation. Coughlin Power Station plays a significant role in meeting the energy demands of Louisiana. Its operation is subject to US EPA regulations under the Clean Air Act, including emission standards for NOx, SO2, and other pollutants. The plant's location in the southern US, a region with high electricity demand, underscores its importance for grid reliability.

The plant's gas fuel type results in lower SOx and particulate emissions compared to coal, but NOx and CO2 emissions remain a concern. Its location in Louisiana, a state with significant industrial activity, means the plant operates in an area with existing air quality management challenges. The facility's age and technology (subcritical vs. supercritical vs. Modern gas plants often employ combined cycle technology for higher efficiency and lower emissions per MWh.
