Mount Clinton Diesel Power Plant, Virginia | US Power Generation Facility

Mount Clinton is a diesel power plant located in Virginia, United States, with a generating capacity of 24 megawatts. The facility is owned and operated by the City of Harrisonburg and is currently operational, serving as a peaking plant to meet electricity demand during periods of high usage. The plant uses oil as its primary fuel, a common choice for diesel-fired peaking units that require quick start-up and flexibility. In the United States, such facilities are subject to the Clean Air Act (CAA) regulations, including National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program, which set limits on emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. As a peaking plant, Mount Clinton plays a critical role in maintaining grid reliability in the Shenandoah Valley region. Its relatively small capacity and operational profile mean it runs only during peak demand periods, reducing its overall environmental footprint compared to baseload plants. The facility supports local energy security and provides backup power when needed.

The plant's use of oil as fuel results in higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewable sources. Its location in a rural area of Virginia reduces direct exposure to dense populations, but emissions may still affect local air quality. Diesel plants typically have lower efficiency and higher emissions than modern combined-cycle gas turbines. Regulatory compliance with US EPA standards helps mitigate environmental impact.
