Equipment malfunction causes power outage in Superior

An equipment malfunction caused a large power outage in the city of Superior for several hours Tuesday, affecting several thousand customers at its peak.

Amy Rutledge, a spokeswoman for Minnesota Power / Superior Water, Light & Power, said the outage started at about 2 p.m.

An equipment malfunction caused the utility's Winter Street substation to go down, which in turn affected a number of feeder lines.

Efforts to switch customers over to another feeder line on Tuesday afternoon were unsuccessful, Rutledge said.

Crews eventually fixed the problem and restored power to all customers at about 6:30 p.m., Rutledge said.

At its peak the outage affected 4,200 customers in Superior, including the downtown, Billings Park, North End and Connors Point areas, Rutledge said.
