Marsh Run Generation Facility: 513.3 MW Gas Power Plant in Virginia, USA

Marsh Run Generation Facility is a gas-fired power plant located in Virginia, United States, with a capacity of 513.3 MW. It is owned by Old Dominion Electric Cooperative and is currently operational. The plant contributes to the region's power generation mix, utilizing natural gas as its primary fuel. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). Gas-fired plants of this scale typically employ combined cycle or simple cycle technology, offering efficient power generation with lower emissions compared to coal-fired units. As a mid-sized gas plant, Marsh Run Generation Facility plays a role in meeting peak demand and supporting grid reliability in Virginia. Its location in a rural area minimizes direct population exposure, while natural gas combustion produces lower CO2, SOx, and NOx emissions relative to other fossil fuels, aligning with regional environmental goals.

The facility's gas-fired operation results in lower carbon dioxide, sulfur dioxide, and nitrogen oxide emissions compared to coal or oil plants. Its location in a rural area reduces direct impact on densely populated zones. The plant's capacity of 513.3 MW places it in the mid-range for gas plants, and its age and technology (likely combined cycle) influence its efficiency and emission profile. Regulatory oversight under the Clean Air Act ensures compliance with national ambient air quality standards.
