Emergency repairs scheduled for Friday are expected to affect more than 600 Emera Maine customers for approximately two hours, officials said.

Work on the electrical system in Ellsworth will impact customers on and around Grant Street, including the Ellsworth Water District facility, Emera Maine said Thursday.

The repairs are scheduled to begin around 9:30 a.m.

The company apologized to customers for the inconvenience, but said the service interruption will allow crews to make the repairs in the safest manner possible.
