All power will be restored in the Tri-State by 11:59 p.m. Wednesday, Duke Energy announced Tuesday.
As of 11 p.m. Wednesday, more than 1,000 people are still without power after storms swept through the area Monday. At its peak, Duke Energy reported more than 166,000 outages. Around 20% of Butler and Warren counties had no power.
Crews from Indiana, Kentucky, Michigan, and North Carolina are helping with repairs.
Duke Energy said crews worked through the night Monday and around the clock Tuesday to assess the damage and make repairs.
At this point, thousands are stuck without AC on the second day of extremely hot weather. The heat index could reach above 100 degrees Wednesday. Tuesday's heat index was 110 in some parts of the region.
"This is the most significant outage event to impact Duke Energy’s Cincinnati and Northern Kentucky service areas in over a decade," Duke Energy said in a statement.
"We appreciate our customers’ patience as our crews work day and night throughout today’s heat advisory to restore power quickly and safely. With today’s temperatures, please stay safe by making arrangements to keep cool and/or stay with family or friends until power is restored."
Duke Energy spokesperson Sally Thelen said customers will not get text updates about power restoration.
"In a storm of this magnitude, we're just overwhelmed," Thelen said.
The entire Tri-State region was under a severe thunderstorm watch on Monday evening. The peak of the storm hit around 7:30 pm. Butler, Warren and Hamilton counties were the hardest hit.
In some parts of the Tri-State, the storms produced winds up to 70 mph.
