Nova Scotia Power is continuing to restore electricity to thousands of customers that lost power later Wednesday afternoon. As of 10:09 p.m., more than 10,000 customers were still without power. At the height of the outages, more than 31,000 were affected. The outage happened after a large piece of protective equipment called a breaker failed at the Trenton substation in Pictou County. "That caused both generating units at the plant to go offline," said Nova Scotia Power spokesperson Tiffany Chase. Most of the affected customers are in the Trenton, Pictou County, Dartmouth and Musquodoboit areas. Chase said crews were immediately dispatched to the scene and staff are working on ways to reroute as many of the affected customer to get electricity back as quickly as possible. Electricity is expected to be restored by 2 a.m. Thursday.
