Half were restored within about 2.5 hr, and county-level outages here have been most common in summer (35% of all records). The busiest year on record was 2022.
Largest single-county outage on record: ~41,253 customers out in Pennington County in November 2025, restored after about 6.8 hr.

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.
