More than 2,700 Westar Energy customers lost power in northwest Lawrence Monday morning, according to the company's website.
The outage affected customers in the northwest part of Lawrence — north of Sixth Street and west of Iowa Street.
Westar Energy spokesperson Gina Penzig said the outage was likely caused by an animal that got into the Lawrence Hills substation, 1250 B North 1800 Road, near the Lawrence Energy Center.
Penzig said the majority of customers affected were without service from 11 a.m. to 12 p.m. As of 2 p.m., power had been restored to all but 60 customers in Douglas County.
Westar reported via Twitter that the outage affected three circuits.
