The remaining electric substation without power is up and running in Hannibal in the wake of Monday's severe weather storm.
The Hannibal Board of Public Works said that crews have worked non-stop since Monday to return power to more than 8,500 customers who lost power.
By Thursday, about 500 customers remained without power.
With the final substation now functioning, crews will turn their attention to more localized efforts to return power to individual homes and businesses.
BPW spokeswoman Cindy Livesay said it's difficult to give an estimation as to how long it will be before the city is back at full force.
We don't have that estimation right now, she said. What's left now are the localized issues; changing out poles, taking out tress, putting in new line fuses. Right now we just don't have a good estimation.
Power returned to Hannibal Middle School Thursday morning as well.
