There's a large power outage that includes much of the city of Grand Rapids, including the downtown and much of the northwest side of town. There are nearly 7,500 customers affected, including Art Prize. The outage means that many traffic lights are not working. Several radio stations are not broadcasting. I do not have a cause, but we know there's a major voltage line that is out. We do not think the outage was weather related. The estimated time of restoration is 6:30 pm. They have delayed opening the doors to the Van Andel Arena for the Griffins game due to the power outage.
