Update - 2:15 p.m.: We are aware of an outage currently affecting the following communities: In Whitehorse: Riverdale, Range Road, Whistle Bend, and parts of Porter Creek. All neighbourhoods North and South of the City. Crews are on site and working to restore power as quickly and safely as possible. Dawson City and Mayo were also affected by this outage. Power has been restored in those communities. Cause of the outage: A trip at our LNG and Whitehorse hydro stations. Why? Not sure. Our first priority is getting the power back on. As soon as power is restored, we will look into what caused it Update - 2:55 p.m.: ATCO Electric Yukon reports that crews are working to get power back on in downtown, Riverdale and north of Whitehorse right now. Update - 3:00 p.m.: ATCO Electric Yukon reports that they are working on restoring power south of Whitehorse right now. Update - 3:45 p.m.: Power is restored to all customers. We've been able to determine that today's outage started when our largest Whitehorse hydro facility (#4) tripped which caused it and our LNG facility to go off-line. We are now looking to find out why the hydro unit tripped in the first place.
Update - 9 p.m: We are aware of outages affecting Dawson City, Mayo, neighbourhoods in Whitehorse, and north and south of Whitehorse. Cause of the outage is unknown at this time. Crews are onsite assessing the scope of the outage and working to restore power as quickly as possible. Updates to follow. Update - 9:20 p.m.: Crews have been able to restore power in Mayo and parts of Dawson. Restoration in Whitehorse and communities north and south of the city will begin shortly. Update - 10:45 p.m. Remaining customers in Dawson have power back as well as the majority of customers in and around Whitehorse. The remainder of customers should have power back on within minutes Update - 11 p.m. All power has been restored. Tonight's outages were caused by a loss in power supply. This means something happened that caused one or more of our power generators to trip. When this happens, the amount of power we can generate and supply to the grid decreases, and the amount of power Yukoners need is more than what is available. That's when the power outage happened. Now, what caused the generators to trip? That's what our team will be working on over the next few days to figure out. Sorry for the trouble tonight's outage caused. Update - February 11, noon: Following a thorough review of Friday’s outage, we’ve been able to determine that the outage was caused by a communications failure. When the failure occurred, our Whitehorse LNG facility, and our Whitehorse Hydro # 4 and Aishihik #3 units tripped. This communication failure is also the reason why Friday’s outage took a bit longer to restore than normal. Since our communication with each power plant was lost, power plants in Dawson, Mayo, Whitehorse and Aishihik had to be operated manually. Thank you again for everyone’s patience and understanding Friday night.
