The plant is owned and operated by the City of Stuart, ensuring reliable power generation for the area. The plant uses oil as its primary fuel, typical for diesel-fired peaking plants that provide flexibility and quick start-up capabilities. In the United States, such facilities are subject to the Clean Air Act (CAA) regulations, including National Ambient Air Quality Standards (NAAQS) and emission limits for criteria pollutants. The plant's small capacity places it in a lower regulatory tier compared to larger baseload units. Gilliam South plays a role in meeting peak electricity demand and enhancing grid stability in the region. Its location in a rural area minimizes direct environmental impact on densely populated zones, though emissions from diesel combustion contribute to local air quality considerations. The plant's operational status underscores its importance to the City of Stuart's energy infrastructure.

The plant's diesel combustion emits CO2, SOx, NOx, and particulate matter, contributing to local air quality impacts. Its location in a rural area reduces exposure to dense populations, but emissions still affect the surrounding environment. The small capacity (4.3 MW) limits overall environmental footprint compared to larger fossil fuel plants. Regulatory oversight under the US Clean Air Act ensures compliance with emission standards.
