The Yukon Energy Corporation has applied for an environmental assessment to build a second dam downstream from the current hydroelectric facility in Mayo.

The project, called Mayo B, would double the amount of power coming out of Mayo from five megawatts to 10 megawatts, according to a news release.

The Mayo grid, which runs from Keno to Dawson, does use diesel when Mayo isn’t sufficient. The hydro power could also be sent to the Whitehorse-Aishihik-Faro grid once a connection is built between Pelly Crossing and Stewart Crossing.

Yukon Energy still needs to apply to the water board for approval and the company is currently seeking a memorandum of understanding with the Na-cho Nyak Dun First Nation to build the dam.

The Yukon government is helping finance the project and is currently lobbying for federal funds to finalize construction plans. (James Munson)
