Hamilton (PA) Diesel Power Plant - Pennsylvania, USA | 19.6 MW Peaking Facility

Hamilton (PA) is a diesel power plant located in Pennsylvania, United States, with a capacity of 19.6 MW. Owned by Hamilton Power LLC, the facility is operational and serves as a peaking plant, typically used during periods of high electricity demand or as backup generation. Its relatively small scale places it within the category of distributed generation assets that support grid reliability. The plant operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program. Diesel-fired units are subject to emissions limits for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. Typical diesel plants of this size use reciprocating engines, which can be started quickly to meet peak demand. As a peaking plant, Hamilton (PA) plays a role in balancing the regional grid, particularly during extreme weather events or when renewable generation is low. Its location in Pennsylvania places it within the PJM Interconnection, one of the largest electricity markets in the US. The plant's environmental footprint is tied to its fuel type, with diesel combustion producing CO2, SOx, and NOx emissions, though its limited operating hours reduce overall impact compared to baseload plants.

The plant's use of diesel fuel results in higher CO2 emissions per MWh compared to natural gas, and it also emits SOx and NOx, which contribute to local air quality concerns. Its location in Pennsylvania, a state with varied air quality standards, means it must comply with EPA regulations under the Clean Air Act. The facility's small capacity and peaking operation mode limit its continuous environmental impact, but its proximity to populated areas could pose localized risks during operation.
