There was a brief power outage last night that affected Riverdale, Grainger, most of Copper Ridge, and areas south of Whitehorse including Tagish, Marsh Lake and Carcross. Power went out at 11:13 p.m. and was restored to everyone within 25 minutes. Some areas had their electricity back on within 13 minutes.
The outage occurred as we were making changes to our system to accommodate the new third hydro turbine that will be installed at our Aishihik plant within the next year. We lost stability on the system and two of our Whithorse hydro units went down. The problem has been resolved and all units are now functioning properly. We apologize to all those who were affected by the outage.
