Monterey Diesel Generation Facility: 6 MW Diesel Power Plant in Virginia, USA

The Monterey Diesel Generation Facility is a diesel-fired power plant located in Virginia, United States, with an operational capacity of 6 MW. Owned by Old Dominion Electric Coop, the facility serves as a peaking plant, providing electricity during periods of high demand. Its location in the mid-Atlantic region places it within the PJM Interconnection grid, one of the largest electricity markets in the world. As a diesel plant, the facility operates using internal combustion engines, which offer rapid start-up capabilities essential for grid reliability. While diesel generation is less common for baseload power due to fuel costs and emissions, it remains a critical component for peak shaving and emergency backup. The plant's relatively small capacity classifies it as a small-scale generation asset, typical for distributed or community-level support. Environmentally, diesel plants emit higher levels of CO2, NOx, and particulate matter per MWh compared to natural gas or renewable sources. However, the facility's limited operating hours as a peaking plant reduce its overall environmental footprint. Its role in maintaining grid stability, especially during extreme weather events, underscores its importance to the local community and the broader PJM system.

The facility operates in a rural area of Virginia, with low population density, which moderates local air quality impacts. Diesel combustion produces NOx and SO2, but the plant's small capacity and intermittent use limit its contribution to regional emissions. The facility is subject to US EPA regulations under the Clean Air Act, including New Source Performance Standards for stationary engines.
