So, if you are a Harrisonville resident, here's everything you need to know: On Thursday night, from 11 p.m. to 1 a.m., repairs will begin on the arresters and ground straps at the city's north substation to ensure the transformer does not become overloaded and cause the whole substation to lose power.
