Eklutna Generation Station
MEA’s Eklutna Generation Station, or EGS, is a new 171-megawatt natural-gas-powered power plant in Eklutna, Alaska. EGS is now serving homes and businesses from Eagle River to the South Denali Princess Lodge.
EGS is powered by Cook Inlet natural gas delivered by Hilcorp, the third-largest, privately held petroleum exploration and production company in the United States.
Each of the low-emission Wärtsilä engines at EGS will operate primarily on natural gas. However, in case of interruption to the gas supply, advanced dual-fuel technology enables the engines to smoothly switch to diesel.
For decades, MEA purchased power from Chugach Electric Association, but members voted to build their own plant and begin generating their own power once the Chugach contract ended.
