Our power generation facilities

It is our goal to deliver safe, reliable power at competitive rates. At the end of December 2020, Chugach had 937.2 megawatts of capacity. This includes Chugach’s share of the jointly owned Eklutna Power Plant. The unit ratings shown are winter time capacities. Chugach also took power from the state-owned Bradley Lake Hydroelectric Project near Homer and from the Fire Island wind project. In 2020, 76 percent of the kilowatt-hours Chugach sold came from natural gas units, 21 percent from hydroelectric resources and 3 percent from wind.
