HYDRO POWERPOWER GRIDS & TRANSMISSION
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.
