Pearl Station Diesel Power Plant, United States | Prairie Power Inc.

Pearl Station is a diesel-fired power generation facility located in the United States, with coordinates 39.4492° N, -90.6141° W. The plant has a capacity of 24 megawatts and is owned by Prairie Power Inc. It operates as a peaking plant, providing supplemental power during periods of high demand. The plant uses oil as its primary fuel and operates under the regulatory framework of the U.S. Environmental Protection Agency's Clean Air Act, including standards for emissions of sulfur dioxide, nitrogen oxides, and particulate matter. Diesel plants of this scale are typically used for grid reliability and emergency backup, and they are subject to New Source Performance Standards and state-level air quality permits. As a peaking facility, Pearl Station plays a role in maintaining grid stability in its region. Its relatively small capacity and operational profile mean it contributes to the local energy mix primarily during peak load events. The plant's environmental footprint is managed through compliance with applicable emission limits and monitoring requirements.

Pearl Station, as a diesel power plant, emits CO2, SOx, NOx, and particulate matter from oil combustion. Its location in a rural area of Illinois may reduce direct population exposure, but emissions contribute to regional air quality. The plant's age and technology (likely reciprocating engines) influence its efficiency and emission profile. Regulatory compliance under the Clean Air Act and state rules helps manage its environmental impact.
