Lakeside Diesel Power Plant, Springfield, Illinois | United States Power Generation

Lakeside is a diesel power plant located in Springfield, Illinois, United States. With a capacity of 5.4 MW, it is a small-scale facility within the U.S. power generation sector, owned by the City of Springfield. The plant operates on oil as its primary fuel, typical for diesel plants used for peaking or emergency backup. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its National Ambient Air Quality Standards (NAAQS). As a diesel facility, it is subject to emissions standards for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. Small diesel plants often use reciprocating engines. Lakeside contributes to the local grid reliability in the Springfield area, providing dispatchable power during peak demand or emergencies. Its municipal ownership underscores its role in community energy security. The plant's environmental footprint is relatively small due to its limited capacity, though diesel combustion produces higher CO2 and pollutant emissions per MWh compared to natural gas.

The plant's use of oil as fuel results in higher CO2, SO2, and NOx emissions per unit of electricity compared to natural gas or renewable sources. Its location in Springfield, a city with moderate population density, means local air quality impacts are a consideration. The small capacity (5.4 MW) limits its overall environmental footprint, but diesel plants are often used for peaking, leading to intermittent operation. Regulatory compliance with EPA emissions standards helps mitigate local pollution.
