A power outage that left more than 7,400 Central Maine Power customers in parts of Brunswick, Freeport, Harpswell and Topsham without electrical service Friday morning was likely caused by a lightning strike, a company spokeswoman said.

Electrical service had been restored to all customers by shortly before 2 p.m., Central Maine Power spokeswoman Gail Rice said.

Customers first began reporting outages around 8:36 a.m., and utility crews tracked the source of the outage to two poles in a remote area on River Road in Brunswick near Interstate 295, Rice said.

“It looked like it was lightning related,” Rice said. “This happened to hit a transmission line that serves a significant substation.”

The strike “completely destroyed” two glass insulators that go on the power lines between poles, she said.

Crews on at least nine trucks worked to restore power from mid-morning to noon, returning power to a first wave of about 1,250 customers by 11 a.m. and all the rest by 2 p.m., Rice said.
