MidAmerican Energy Co. is reporting 839 customers are without power in Rock Island as of 8:30 p.m. today because of a weather-related outage.
Rock Island police said a transformer blew out in the area of Black Hawk Road and 38th Street.
The utility company also is reporting 32 customers in Moline and 59 customers in Rock Island County without power.
Company spokeswoman Ann Thelen said the transformer problem was probably due to a lightning strike, but that has not been confirmed.
MidAmerican workers are on the scene investigating the problem, Thelen said, adding that crews will work to get power restored as soon and as safely as possible.
No power outages were reported in the Iowa Quad-Cities as of 8:45 p.m.
