KEA operates an isolated grid system. The main power source comes from three hydroelectric turbine generators at Terror Lake. KEA also operates four independent diesel generation facilities (Kodiak Generating Station, Nyman Power Plant, Swampy Acres Plant and Port Lions) which are a mixture of diesel reciprocating engines and a diesel-fired combined cycle generation unit. KEA added 4.5 MW of wind power in July 2009 with the completion of Phase I of the Pillar Mountain Wind Project. Due to the great success of this project, KEA moved forward with Pillar Mountain Phase II in the fall of 2012. Phase II included an additional 4.5 MW of wind power and a 3 MW energy storage system.
