At approx. 7:20pm on Thursday, March 3, GVEA’s Healy Unit 2 suffered damage to the coal feed system due to spontaneous combustion, commonly known in the industry as a “puff.” This also caused a small fire, which the Healy Volunteer Fire Dept. responded to, and was quickly extinguished. There were no injuries.
Healy Unit 1 was shut down due to the event and is due to be back online this evening.
GVEA is assessing the damage. An inspection and root-cause analysis will be performed next week. Healy Unit 2 will be down for a period of time, while the analysis and repairs take place.
