YEC generates virtually all of Yukon's electricity supply, and distributes power to a third of the locations outside of Whitehorse.
A second grid, brought on-line in 2004, connects Dawson City (reliant on diesel power from 1966 to 2004) via Stewart Crossing to Mayo, and beyond to the YECL-served communities of Elsa and Keno City, all drawing on the 5 MW hydro facility just north of Mayo that had mines at Elsa as primary customer until 1989.
and Liberal party mandates, this project was not developed, and Pelly Crossing remained on its own YECL diesel generator.
Off the grid, Yukon Electrical Company Limited operates diesel generators to serve its customers in Watson Lake-Upper Liard, Swift River, Burwash Landing, Destruction Bay, Beaver Creek and Old Crow.
Yukon has no connections to the continental power grid, therefore, YEC cannot sell to or buy from networks in Alaska, British Columbia, Alberta or the Northwest Territories.
