Cascade Diesel Power Plant | Cascade, Iowa, United States

Cascade is a diesel power plant located in Cascade, Iowa, United States, with a capacity of 5.2 MW. The facility is owned and operated by Cascade Municipal Utilities and is currently operational. As a diesel-fired plant, it serves as a peaking or backup power source for the local community. The plant uses oil as its primary fuel, typical for smaller diesel generators in the United States. Diesel plants of this scale often employ reciprocating engines. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency's Clean Air Act, which sets emission standards for criteria pollutants such as SOx, NOx, and particulate matter. Cascade plays a role in ensuring grid reliability for the Cascade area, providing power during peak demand periods or emergencies. Its relatively small capacity positions it as a local resource rather than a major regional generator. The plant's environmental footprint is limited by its size and intermittent operation, though diesel combustion produces CO2 and other emissions.

The plant's use of diesel fuel results in CO2, SOx, and NOx emissions, though its small capacity (5.2 MW) and likely intermittent operation reduce overall impact. Located in a rural area of Iowa, the facility is not in close proximity to major population centers, lowering local air quality concerns. The plant must comply with U.S. EPA emission standards under the Clean Air Act, including New Source Performance Standards for stationary engines.
