Storms swept the region about 6:40 p.m. Sunday, leaving most of Lincoln County without electrical power.
The storm hit Danville, but power remained active until 8:40 this morning when a squirrel got into a substation and caused an outage in northern Danville.
"When something touches the substation, it causes trauma to the system," said Kentucky Utilities spokesman Cliff Feltham.
According to Feltham, the outage began at 8:40 a.m. and lasted until 9 a.m. The 20-minute power hiatus was one of few outages in the area not caused by Sunday night's storm.
"We may have had a handful of power bumps, but no outages, nothing of large substance," said Feltham. "Especially compared to the 11,000 customers out of power in Lexington."
