Butte, Mont. – August 7, 2017 – NorthWestern Energy has scheduled a power outage for the community of Ennis and nearby Madison Valley on August 8, 2017, beginning at 2 a.m. and ending at about 5 a.m.

The outage, which will affect about 3,100 customers, will allow NorthWestern crew to safely make upgrades to the electric system in the area.

The upgrades are intended to minimize the number and duration of outages due to storms and other events and improve the reliability of service to area customers.
