DTE Energy customers spend a chilly night without power in northeast Ann Arbor

A transformer failure on Yorktown Drive caused the power outage, which began about 6:20 p.m. Sunday evening, DTE spokesman John Austerberry said.

Power was restored for about 80 customers around 9:40 p.m. Sunday, but service for the rest will be out until the utility can replace the pole that held the transformer, Austerberry said.

Nelson Bacigalupo spent a chilly night under blankets in the neighborhood. He said the temperature in his home this morning was about 45 degrees.

"My main concern is when is the power going to be on," he said. "There has been several of these kinds of outages without a storm or anything."

The affected area as shown on the DTE power outage map, lies to the north of Plymouth Road and west of US-23.

The outage area is shown in green on the map.
