Dillingham Diesel Power Plant, Dillingham, Alaska | USA Power Generation

Dillingham is a diesel power plant located in Dillingham, Alaska, United States. With a capacity of 11 MW, it is a small-scale facility serving the local grid. The plant is owned and operated by Nushagak Electric Cooperative, Inc., and is currently operational. The plant uses oil as its primary fuel, typical for remote Alaskan communities where fuel oil is a common energy source. Diesel power plants like this one operate under the U.S. Environmental Protection Agency's (EPA) Clean Air Act regulations, including National Ambient Air Quality Standards (NAAQS) and New Source Performance Standards (NSPS) for stationary engines. These regulations control emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. As a key electricity provider in a remote area, Dillingham plays a vital role in supporting local residences and businesses. Its operation is essential for community energy reliability, though its reliance on oil contributes to greenhouse gas emissions. Typical diesel plants in Alaska are older and may have lower efficiency compared to modern combined-cycle units.

The plant's use of oil as fuel results in CO2, SOx, and NOx emissions, which are regulated under the Clean Air Act. Its location in Dillingham, a remote Alaskan community, means it serves a small population but may have limited access to alternative energy sources. The plant's capacity of 11 MW is small, but its environmental impact is localized. Proximity to populated areas is direct, as it supplies the local grid.
