McWilliams Gas Power Plant | Alabama, USA Power Generation

McWilliams is a gas-fired power plant located in Alabama, United States, with a capacity of 654 megawatts. It is owned and operated by PowerSouth Energy Cooperative, a generation and transmission cooperative serving members across Alabama and northwest Florida. The plant plays a key role in meeting the electricity demands of the region. The facility operates on natural gas, a fuel that produces lower CO2 emissions compared to coal but still contributes to greenhouse gas emissions. In the US, gas-fired power plants are subject to EPA regulations under the Clean Air Act, including New Source Performance Standards and emission limits for NOx and SO2. McWilliams provides reliable baseload or peaking power to the cooperative's member utilities. Its location in southern Alabama supports the local energy infrastructure, and its capacity places it in the medium-to-large scale for gas plants. The plant's operational status ensures continued service to the community.

The plant's gas fuel type results in lower particulate and sulfur emissions compared to coal, but it still emits CO2 and NOx. Its location in a rural area of Alabama reduces direct exposure to densely populated centers, though regional air quality may be affected. The facility operates under US EPA regulations, including the Clean Air Act and state implementation plans for air quality.
