Healy Clean Coal Project was a clean coal technology demonstration program consisting of a coal fired electrical power station located in Healy, Alaska in Denali Borough. The project was a demonstration of the TRW Clean Coal Combustion System and the Babcock & Wilcox/Joy Spray Dryer Absorber (SDA) System designed to reduce oxides of nitrogen (NOX) and sulfur dioxide (SO2) emissions while burning a variety of coal types, including waste coal. The plant still operates as Healy Unit 2 but without the emissions-reduction technology.
Read more on WikipediaThe Healy power plant, located in Denali County, Alaska, has a total capacity of 92.8 MW. The primary fuel source is lignite coal, but the plant also utilizes petroleum liquids. Operated by Golden Valley Electric Association Inc, the facility began operating in 1967 and consists of three generators employing conventional steam coal technology. Healy is considered a hybrid plant due to its use of multiple fuel sources.
In the most recent year with available data, the plant generated 442,824 MWh of electricity, achieving a capacity factor of 54.5%. Healy operates within a balancing authority area designated as "No BA". The plant holds the distinction of being the largest of its kind in Alaska, ranking 1 of 1 within the state. Nationally, it is ranked 9 of 9 among similar facilities.
