Wind power uses the kinetic energy of wind to move turbine blades that drive a generator to produce electricity. Most utility scale wind farms have units that generate between one to three megawatts each. The wind turbines are mounted on steel towers between 60 and 90 metres tall with three 20 to 40 metre-long blades.



CBER Consulting Services completed the inventory of wind energy sites for the 2016 Resource Plan.

From an initial list of 27 sites, seven were selected for further consideration based on wind speed, distance to transmission lines, road access, and land ownership.

The seven include:

  • Miller’s Ridge (near Carmacks)
  • Kluane Lake
  • Cyprus Mine (near Faro)
  • Thulsoo Mountain (near the Aishihik generating facility)
  • Sugarloaf Mountain (near Carcross)
  • Tehcho (near Stewart Crossing; formerly named Ferry Hill)
  • Mount Sumanik (near Whitehorse)

Yukon’s climate means icing on the turbine blades can occur at high elevations in winter, making operating a wind turbine challenging. Of the seven sites selected, only the site at Kluane Lake is at a low elevation.

Even with energy losses due to ice build-up on the turbine blades in winter, higher winds mean most of the electricity would be generated between October and April. This timing complements Yukon’s energy needs, which are highest in winter. They also complement  Yukon Energy’s existing hydro assets, which can become restricted in winter when there is less water available for generation.

While wind is generally considered to have low environmental impacts, wind projects can have large footprints that can impact local wildlife.
