Nearly 30,000 homes and businesses were without power in Eastern Kentucky on Monday night, and some might not get their electricity back until Saturday.
Kentucky Power, working to restore outages in 13 counties, called in about 400 outside utility workers to help after storms left broken utility poles and spans of downed lines.
A windstorm that swept through Friday night left 63,850 Kentucky Power customers without electricity.
By Sunday evening, about 70 percent of those had their power back, then a thunderstorm knocked out 22,000 more customers. Many of them were people whose service had just been restored.
Never miss a local story.
Ronn Robinson, communications manager for Kentucky Power, said the number of customers to whom power had been restored had risen steadily throughout the day Monday.
But as of 8 p.m., 27,046 of Kentucky Power's 172,865 customers were without power.
Pike County was one of the hardest hit, with more than 5,500 customers without power as of 8 p.m. It is likely to be Saturday before all of them have it back.
Brandon Roberts, spokesman for the Pike County judge-executive's office, said the county was using its 15 senior citizen and community centers as cooling centers for residents without air conditioning.
"It's widespread, but it's sporadic," he said of the outages, noting that one side of a street might have power but the other side might not.
Thousands of electrical customers in Boyd, Carter, Floyd, Greenup, Knott, Lawrence, Martin and Rowan counties might be without electricity until Friday, Kentucky Power said.
Customers in Magoffin and Johnson counties could see their power restored Wednesday, and the 100 customers in Perry County who were without power Monday probably will get it back by Tuesday.
In response to the outages, Gov. Steve Beshear ordered the state Transportation Cabinet to issue an emergency declaration. It exempts utility repair vehicles from other states from restrictions on standard hours of service and allows them to bypass weigh stations.
