Power was reported out to some areas of Ann Arbor Monday morning and to some parts of the University of Michigan Campus.
DTE Energy spokesman Len Singer said about 4,000 customers appeared to be affected, but he could not provide an exact geographic area affected. The DTE power outage map showed a large area of the north side of the city without power at 10:20 a.m.
Diane Brown, University of Michigan Police Department spokeswoman, said the outage, which occurred at 9:54 a.m. was widespread on the campus though she did not know the complete extent. Some areas were reporting power coming back just after 10 a.m. By 10:40 a.m., she said power was being restored building by building.
The university has multiple power feeds from DTE, she said, and so was able to get power from another feed after the outage.
Several people were stuck in elevators for a while after the outage occurred. She said that's a common occurrence whenever there's an outage or a power surge. The elevators have to be manually reactivated when that happens, she said.
Singer said the outage appeared to be affecting a substation in the area that controls a couple of circuits.
No restoration estimate was immediately available. “We are in the process of checking out what is going on,” Singer said.
Outage areas are shown in Red and Yellow on the map.
