The Sun Prairie Utilities says a power outage Saturday morning was caused by an animal at a utility substation.
The utility said on its Facebook page that a squirrel was the reason some Sun Prairie customers were experiencing an outage. Crews were working to restore power and divert the power source away from the Bird Street substation.
"(Crews) are going to switch all the load off Bird, to other substations," Sun Prairie Utilities wrote on its Facebook page at 10:18 a.m.
According to an advisory from the Sun Prairie Police Department, power was restored to all residents by 11:29 a.m. Saturday.
