This morning, DTE crews are working along Jefferson Avenue in the Harbortown area to restore power to 1,000 customers who lost power Wednesday night. DTE reports another 2,000 powerless customers are scattered across the city.
DTE Energy reports the problem is due to a transformer failure.
Workers on the scene say a trunk line at a substation - or main delivery line - went down before 8 pm last night.
A large replacement part was delivered. Repairs have been going on all night.
Residents in Lafayette Place, a high rise apartment building, had their power restored at 5:30 am. Many of the elderly residents were trapped in their units because the elevators in the building were not working.
So far power has been restored to parts of the north side of Jefferson near Mt. Elliott.
But many pockets of the south side of Jefferson remain - starting from I-375 and the outages continue to the east to Mt. Elliott.
The Salvation Army and Detroit EMS are on scene to assist residents.
