Healy Clean Coal Project was aclean coal technology demonstration program consisting of acoal firedelectricalpower station located inHealy, Alaska inDenali Borough. The project was a demonstration of theTRW Clean Coal Combustion System and theBabcock & Wilcox/Joy Spray Dryer Absorber (SDA) System designed to reduceoxides of nitrogen (NOX) andsulfur dioxide (SO2) emissions while burning a variety of coal types, includingwaste coal. The plant still operates asHealy Unit 2 but without the emissions-reduction technology.
The project constructed a plant adjacent to Golden Valley Electric Association (GVEA) 25 MW coal plant Healy Unit 1. Construction occurred from 1995 to 1997 at a cost of around $300 million. The facility operated briefly following its construction as part of the demonstration program, but has been shut down since 2000.[1] The research project is considered "complete" by the Department of Energy. The plant was sold in 2012 to the GVEA to resume power production.[2] It restarted in 2015, only to close the next year after an explosion. It resumed commercial operation in November 2018.[3]
Healy Unit 2 will be shut down in 2024 and Unit 1 will receive an emissions control system.[4]
According to Golden Valley Electric Association (GVEA) the facility cost around $300 million, with theUnited States Department of Energy contributing $120 million, the Alaska Legislature contributing $25 million, theAlaska Industrial Development and Export Authority (AIDEA) contributing $150 million and both GVEA & Usibelli Coal Mine contributing $10 million in addition to in-kind contributions.[2]
