AROOSTOOK COUNTY, Maine (NEWS CENTER) -- A major power outage that hit northern Maine Tuesday evening left upwards of 13,000 Emera customers without electricity for several hours.

The outages were reported from Sherman all the way up to Caribou. The first outage was reported just after 5 p.m., and the numbers continued to climb.

Emera spokesperson Bob Potts said crews are investigating the cause and will make any repairs, and get all customers restored safely and as quickly as possible.

"The public is reminded to never touch a downed power line or a tree in contact with a downed line," he said. "Motorists are urged to slow down or move over and change lanes, when possible, if approaching utility crews working on roadways. Customers who use generators or alternate heating sources are reminded to ensure they are used in accordance with manufacturer's guidelines at all times."

At 6:47 p.m., ACSO tweeted most of the impacted areas were reporting restoration of power.

"If you need us, dial 800-432-7842, or dial 911 for a serious emergency," they wrote in a Facebook post. "All of our services are up and running on backup power and we are available if you need us."
