HAY RIVER, NWT (March 12, 2021) – The Northwest Territories Power Corporation (NTPC) announced today that the Snare Rapids Hydro Unit has returned to service. The unit was shut down on February 2 when NTPC’s control centre received a number of alarms indicating that the generator was experiencing problems.
The failure of equipment in the main generator caused the original shutdown. Two of the 56 rotor poles in the unit failed and had to be sent offsite for repair. The unit has been successfully tested over the past 24 hours and is now considered back to fully functional.
Total cost of the shutdown is unknown at this time. Diesel replacement costs during the shutdown totaled approximately $630,000.
NTPC is a wholly owned subsidiary of NT Hydro, which in turn is 100 percent owned by the Government of the Northwest Territories.
"NTPC staff and contractors worked hard to return Snare Rapids to service on the lower end of our original time estimate for repair. Aging hydro infrastructure will continue to pose challenges in maintaining reliable electricity supply to customers in the North and South Slave regions”
