Northwest Territories Power Corporation Identifies Faulty Power Lines as Cause of Yellowknife Outage
The Northwest Territories Power Corporation (NTPC) confirmed that a fault on power lines connecting Yellowknife's diesel generators and Jackfish Lake substation caused a four-hour outage. Initial assumptions of wildlife interference were ruled out after crews inspected the connections. NTPC also reported a separate outage in Tuktoyaktuk due to a breaker failure. Minister Caroline Wawzonek emphasized the need for improved connectivity between hydro grids to reduce future outages.

A power outage in Yellowknife, N.W.T., was caused by a fault on the power lines connecting diesel generators and the Jackfish Lake substation, lasting approximately four hours. The Northwest Territories Power Corporation (NTPC) initially suspected wildlife interference.
Crews had to inspect all connection points and restart the hydroelectric system, which delayed restoration. A separate outage in Tuktoyaktuk was due to a breaker failure affecting both the community and power plant.
Minister Caroline Wawzonek highlighted the necessity of connecting NTPC's two hydro grids to prevent prolonged outages. NTPC is also clearing vegetation near transmission lines and completing a study to enhance grid reliability.
