Hagood Gas Power Plant | South Carolina, United States

Hagood is a gas-fired power plant located in South Carolina, United States, with a capacity of 177.3 MW. The facility is owned and operated by Dominion Energy South Carolina Inc, a major utility in the region. As a gas power plant, it plays a role in meeting the electricity demands of the surrounding area. The plant operates under the regulatory framework of the United States Environmental Protection Agency (EPA), including the Clean Air Act and associated rules such as the Cross-State Air Pollution Rule (CSAPR). Gas-fired plants like Hagood typically use combined cycle or simple cycle technology, with modern facilities achieving higher efficiency and lower emissions compared to older coal plants. The 177.3 MW capacity places it in the medium-scale range for gas power plants. Hagood contributes to the local energy mix, supporting grid reliability and economic activity in South Carolina. Its operation aligns with the broader trend of natural gas playing a key role in the U.S. power sector due to its lower carbon intensity relative to coal. The plant's location near populated areas underscores the importance of compliance with air quality standards.

As a gas-fired plant, Hagood emits CO2, NOx, and other pollutants, though at lower levels per MWh than coal plants. Its proximity to populated areas in South Carolina necessitates adherence to EPA air quality standards under the Clean Air Act. The plant's age and technology (subcritical vs. combined cycle) influence its environmental footprint, with modern combined cycle units achieving higher efficiency and lower emissions.
