This project was completed in December 2021 on budget and COVID-free. It was needed to improve power quality and reliability, improve public safety and enable future growth around Mayo and Keno.
The Mayo to McQuesten Transmission Project consisted of replacing the 65-year-old transmission line between Mayo and the McQuesten substation and adding system protection equipment at Yukon Energy’s Stewart Crossing South substation.
This project was needed to:
improve power quality and reliability in the area;
improve public safety by replacing old poles and wires with new equipment;
allow for future growth and development in the region; and
put Yukoners back to work and support the economy.
This $34 million project was funded in part by the Government of Canada and Yukon Development Corporation. Industrial customers that use the new transmission line will pay 85 per cent of the fixed annual costs of the line.
New electrical equipment has now been put into service, marking the completion of the Mayo to McQuesten Transmission Line Replacement Project. With total project costs coming in just shy of $34 million, the project was delivered on budget and without any cases of COVID-19.
Construction of the Mayo to McQuesten Transmission Project began in June 2020 after strict COVID-19 safety plans were put in place to keep area residents, First Nations Citizens and contractors safe. The new transmission line was energized on March 15, 2021. Upgrades to the Stewart Crossing South substation are expected to be completed by the end of 2021.
