YARMOUTH – Central Maine Power says it’s restored power to nearly all of the 6,000 customers in Cumberland, Androscoggin and Somerset counties who were without power earlier in the day.

The utility says a transmission line coming out of the Yarmouth substation was out, causing the problem.

The total number of customers affected, more than 6,000 Sunday morning, was down to 19 by mid-afternoon.

 

PREVIOUS UPDATE:

More than 6,000 people in Cumberland County are without power, and Central Maine Power Co. has not determined the cause of the outage.

A piece of transmission line coming out of the Yarmouth substation is out, but CMP doesn’t know why — or how long it will take to fix.

The outage, which began at 9:14 a.m., is affecting 6,123 customers in Gray, New Gloucester, Raymond, Cumberland, Falmouth, Windham, Durham and Pownal, according to CMP.

A recording on the company’s hotline from 9:20 a.m. estimated power would be restored in two hours, but a spokeswoman said the company couldn’t predict the amount of time the restoration would take because the cause is still unknown.

A dispatcher at Cumberland County Regional Communications said the outage has affected several traffic lights, but as of 10:30 a.m., no accidents had occurred as a result.
