Update: Power has been restored to most customers as of noon Sunday.

GRAND RAPIDS, Mich. -- A power outage Sunday morning left police working to respond to hundreds of alarms.

For some systems, the lack of power causes it to automatically send an alert there may be a problem.

As of 9 a.m. Sunday, Nov. 6, the outage affected more than 4,400 Consumers Energy customers.

The outage sweeps through the city's East Side, reaching almost as far north as Leonard, and as far south as Sherman Street. It also goes from the river in the west past Plymouth Avenue in the east.

WZZM 13 spoke to Grand Rapids police about what may be the caused of the outage. They say a transformer near Fuller Avenue may have exploded.
