Source: EAGLE-I (Oak Ridge National Laboratory / U.S. Department of Energy), county-level
records 2014–2025, replayed through the same event rules as our tracking archive above with two differences: outages shorter than
half an hour count here, and a reading above twice the county's customers or households is capped. They cover a far longer period
than we have been tracking — a different set of outages, so the two typical times differ. These are federal historical records,
not events tracked live by this site.
