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.
