Power Outage: Over

A power outage at 9:50 a.m., leaving several thousand Ann Arbor residents without power, resulted from an open relay in a substation, according to DTE media relations. It’s analogous to a circuit breaker tripping in a household. Once it was reset, power was restored – a bit after 11 a.m, according to DTE.  DTE is following up to determine the cause of the open relay.
