Most Butler County residents who lost power during this week's derecho should have their lights back on by the end of Thursday, Aug. 13, Duke Energy says.

The utility has restored power to roughly 223,000 of the more than 261,000 customers knocked offline since a powerful derecho tore through Greater Cincinnati on Tuesday, Aug. 11, according to a Duke Energy press release issued Thursday afternoon. That leaves 38,861 customers still without power regionwide, including 32,485 in Ohio.

Duke has not published a Butler County-specific outage count for Thursday. When the storms first hit Tuesday night, more than 2,000 Butler County customers lost power, as we reported Aug. 11. A downed tree on Hamilton Richmond Road in Butler County was among the damage documented during the storm, Fox 19 reported.

Duke Energy storm director Andy Cassidy said Thursday that nearly all customers who can safely receive service will be restored by end of day. "Our crews have made significant progress under extremely challenging conditions, but we still have substantial work ahead of us," Cassidy said in a statement reported by WLWT.

The outage map showed restoration estimates of 11:59 p.m. Thursday for many affected areas. Starting at 7 p.m. Thursday, individual customers should be able to see their specific estimated restoration time at outagemaps.duke-energy.com.

Some outages, particularly those involving broken poles, downed lines or significant equipment damage, may take longer to repair beyond the Thursday target.

What slowed restoration

Multiple rounds of severe weather followed the initial derecho, including lightning and high winds that forced crews to pause work for safety. Duke deployed more than 2,000 lineworkers, tree trimmers and damage assessors, pulling in reinforcements from Indiana and the Carolinas.

The scale was historic.

Duke spokesman John Juech told the Cincinnati Enquirer on Wednesday, Aug. 12, that this was "the highest count of outages and dispersion of damage I've seen across this region in my time at Duke."
