About 650 customers served by the Shingleton substation off Highway 28 about 10 miles southeast off Munising are without power due to equipment failure.
The outage began around 3:00 this afternoon. Repair of the equipment could take until tomorrow, but UPPCO officials are evaluating options that would allow those customers to be served by a different substation while repairs are made.
If “switching” the customers to another substation is feasible, service could be restored within another two or three hours. If a switch can’t be made, it’s likely the customers will remain without power until sometime tomorrow.
