The line will improve power reliability in the Mayo and Keno areas.
The new transmission line between Mayo and the McQuesten substation was energized earlier this week marking the completion of the first stage of the Mayo to McQuesten Transmission Line Replacement project. The project will improve power quality and increase reliability in the Mayo and Keno areas, improve public safety, and support future growth and development in the region with more renewable electricity.
The Mayo to McQuesten Transmission Line Replacement project takes place on the Traditional Territories of the First Nation of Na-Cho Nyäk Dun and Selkirk First Nation. It consists of two major stages: building a new 31 kilometre, 138 kilovolt transmission line to replace a 65-year-old transmission line that had reached end-of-life; and adding system protection equipment at the Stewart Crossing South substation to improve power quality in central Yukon.
On September 5, 2019, the Government of Canada announced a contribution of over $22.7 million towards the project through the Green Infrastructure Stream (GIS) of the Investing in Canada infrastructure plan.
