GRUNDY CENTER — Most of the city of Grundy Center went without power for several hours Tuesday morning.

In a Facebook post, the Grundy Center Police Department said power had been restored by about 10:15 a.m., and they do not believe foul play is suspected.

Grundy Center Municipal Utilities (GCMuni) started rolling blackouts just before 10 a.m., and the Grundy Center Community School District canceled classes due to the outage.

Grundy Center Mayor Paul Eberline said a part burned out at the substation right by the utility plant, and because of struggles with getting the breaker going again, they were required to call in engineers from Cedar Rapids to work on the problem.

Eberline credited GCMuni employees and the city’s public works department for their efforts to get power restored.

“My guys were working so hard… Everybody was working hand in hand. It was going really well. We just couldn’t get that (breaker) to sync up,” he said. “(There are) lessons learned, and a couple things we’ll talk about what we can improve and we’ll go from there. But a good effort by everyone involved.”
