Update: Brown-Out Affecting About 500 Customers in Rochester

About 500 DTE Energy customers in the area southeast of Rochester and Runyon roads remained without power or in a brown-out state on Tuesday morning, according to a DTE spokesman.

John Austerberry of DTE said there was no estimate as to when the power there would be fully restored. He advised residents to turn off any motor-driven devices (including air conditioners) and also to unplug power devices. Austerberry said the cause is unknown.

About 1,600 customers in Rochester and Rochester Hills lost power on Monday afternoon, mostly in the area between Adams and Livernois north of Walton; those customers' power had been mostly restored by Tuesday, according to DTE.
