Historical outage patterns in Montana
Federal outage records (EAGLE-I, kept by the U.S. Department of Energy)
contain 4,049 county-level outage records (200+ customers at peak) in Montana between 2014 and 2025 for the 48 counties the federal record covers — 21 of them major events of 10,000+ customers.
Half were restored within about 3 hr, and county-level outages here have been most common in summer (34% of all records). The busiest year on record was 2024.
Largest single-county outage on record: ~55,225 customers out in Missoula County in July 2024, restored after about 3.8 days.
Months that hit the widest area at once — these rank among the three largest outages ever recorded in the most counties: December 2025 (18 counties), June 2021 (6 counties) and September 2024 (5 counties).

historical records, not outages tracked live by this site. Statewide figures aggregate the same per-county records shown on each county page below;
the statewide restoration figure is the typical (middle) value across the per-county typical times, weighted by how many records each county has. A county appears in a “widest area” month when that month
produced one of its three largest recorded outages.
