HAY RIVER, NWT (February 4, 2021) – The Northwest Territories Power Corporation (NTPC) announced that the Snare Rapids Hydro Unit has been offline since approximately 7:45 pm on Tuesday, February 2. The loss of eight megawatts of generation from the North Slave electricity system has been offset by diesel generation at the Jackfish Generating Plant.
The unit at Snare Rapids automatically shut down on Tuesday, February 2 when NTPC’s control centre received a number of alarms indicating that the generator was experiencing problems. The incident causing the shutdown did not have a measurable impact on the local environment. The automatic shutdown resulted in a city-wide outage in Yellowknife that lasted approximately 20 minutes. NTPC staff have been trouble-shooting since the shutdown to determine the extent of the problem and identify the work required to return the unit to service.
The timetable for returning Snare Rapids to service is unknown at this time.
If additional staff or contractors from outside the Northwest Territories are required to repair the unit, NTPC will work with ProtectNWT to ensure that all required directives and protocols related to worker safety are followed.
NTPC is a wholly owned subsidiary of NT Hydro, which in turn is 100 percent owned by the Government of the Northwest Territories.
“Aging infrastructure continues to make it a challenge to maintain reliable electricity service to our customers. COVID has created additional obstacles to completing maintenance activities that are required to keep our key assets operating well. We will work safely and as quickly as possible to bring Snare Rapids back online.”
