Gerald Andrus Gas Power Plant | Mississippi, USA

Gerald Andrus is a gas-fired power plant located in Mississippi, United States, with a capacity of 781.4 MW. The facility is owned and operated by Entergy Mississippi LLC and is currently operational, contributing to the state's power generation portfolio. The plant operates on natural gas, a fuel that produces lower CO2 emissions compared to coal but still requires compliance with federal and state environmental regulations. As a gas-fired facility, it falls under the U.S. EPA's Clean Air Act standards, including New Source Performance Standards and the Acid Rain Program. The technology likely involves combined-cycle or simple-cycle gas turbines, typical for modern gas plants. Gerald Andrus plays a significant role in meeting the energy demands of Mississippi's residential, commercial, and industrial sectors. Its location in the Mississippi Delta region supports grid reliability and economic activity, while its gas-fired design aligns with the broader U.S. trend toward cleaner fossil fuel generation.

The plant's gas-fired operation results in lower sulfur dioxide and particulate emissions compared to coal plants, but it still produces nitrogen oxides and carbon dioxide. Its location in a rural area of Mississippi reduces direct exposure to dense populations, though regional air quality is subject to EPA NAAQS. The facility's age and specific technology (subcritical vs. Modern gas plants typically achieve higher efficiency and lower emissions.
