Over 3,000 Chatham residents were without power for a brief period of time on Wednesday morning.
The Entegrus outage began at around 9:50 a.m. on Wednesday due to a part failure on the electrical power system.
The outage mostly affected northeast Chatham, with McNaughton Ave Public School going without power, as well as an area of southeast Chatham.
The outage was quickly resolved, with the number of affected residents dropping to under 100 in roughly 20 minutes.
