As many as 1,000 Lawrence households on the west side of town were without power for more than an hour Friday.
Power went out shortly after 4 p.m. Friday and was restored around 5:20 p.m.
Gina Penzig, spokeswoman for Westar Energy, said the outage was caused by general equipment failure.
The outage affected customers bounded by Harvard Road to the north, Bob Billings Parkway on the south, Kasold Drive to the east and Wakarusa Drive to the west.
Later Friday, police closed part of the South Lawrence Trafficway north of U.S. Highway 40 for several hours to allow Westar workers to repair a utility line that had fallen. Those repairs were not related to the power outage.
