DETROIT (WWJ) – Some big Detroit buildings lost power late Monday afternoon — leaving some people trapped in elevators.

Power was restored to the Renaissance Center and most other buildings just after 6:30 p.m.

One witness told WWJ Newsradio 950 the Ren Cen was running on generator power and some in the building were stuck in elevators. There was no immediate word as to how many.

DTE Energy spokesman Scott Simons the blackout was the result of a problem at a substation and crews are working on it.

GM spokesman Patrick Morrissey says workers were given the option of remaining at the building or leaving for the day.

Detroit mayoral spokesman John Roach says City Hall has not lost electricity because the outage is not affecting the city’s power grid.

Meanwhile, DTE officials say 41,000 customers were still without power following Sunday night’s storms. In total, some 95,000 DTE Energy customers lost service late Sunday night and early Monday morning.
