Centennial Generating Station - Diesel Power Plant in Moorhead, Minnesota, USA

Centennial Generating Station is a diesel power plant located in Moorhead, Minnesota, United States. With a capacity of 11.5 MW, it is a small-scale facility within the U.S. power generation sector, typically used for peak demand or emergency backup. The plant is owned by the City of Moorhead and is currently operational. The plant operates on oil (diesel) as its primary fuel, which is common for peaking plants due to quick start-up capabilities. In the U.S., such facilities are subject to emissions regulations under the Clean Air Act, including National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program. Diesel plants often use reciprocating engines or combustion turbines. Centennial Generating Station plays a role in ensuring grid reliability for Moorhead and the surrounding region. Its small capacity and oil-fueled operation make it suitable for meeting short-term demand spikes or providing backup during outages. The plant's location in a northern climate may also support winter reliability needs.

The plant's oil-fueled operation results in higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewable sources. Its location in Moorhead, a city with a population of around 44,000, means emissions may affect local air quality. However, as a peaking plant with limited operating hours, its overall environmental impact is moderate. The facility is subject to U.S. EPA emissions standards, including those for hazardous air pollutants.
