Power has been restored to all but six Westar customers, according to the company's website.
An arcing power line at Wakarusa and Inverness drives has left about 170 Westar Energy customers in Douglas County without power, according to a Westar Energy spokesperson.
About 940 customers in the county lost power at around 8:45 p.m., but many of those were turned back on by 9:30 p.m.
A map on the website shows that the majority of the outages are in central and west Lawrence.
A Westar spokesperson said that crews are currently working on the problem and, while they could not estimate how long those repairs would take, expected it to be fixed by the end of the night.
