About 700 homes south of Laurel were without power for about two hours today due to an outage at the Yellowstone Valley Electric Cooperative's south Laurel substation.
The power to the substation is supplied by NorthWestern Energy through a transmission line that was disrupted, said Terry Holzer, general manager at Yellowstone Valley Electric Cooperative.
The power went out at about 2 p.m. and was restored at about 4 p.m. NorthWestern Energy rerouted power to the substation through another transmission line to restore power to customers, Holzer said.
The customers who lost power live about four miles south of Laurel along U.S. Highway 212 to Fort Rockvale and the area around the intersection of U.S. Highway 310.
The outage was the second in the past 30 days. The first occurred in mid-December.
"We're going to be talking to NorthWestern Energy about the problem next week to discuss long-term solutions to improve the power supply to the substation," Holzer said.
