DETROIT, Maine — More than 12,000 Central Maine Power customers in parts of 17 towns lost their power Thursday because of a malfunctioning mobile substation, according to a CMP spokeswoman.
Crew members who were performing maintenance on an electrical substation on Route 11 in Detroit had connected a mobile substation to a transmission line so they could perform the repairs. A mobile substation is a large piece of equipment mounted to a flatbed trailer, according to CMP spokeswoman Gail Rice.
The mobile substation failed at about 11 a.m., cutting power to about 12,400 CMP customers. By 1:30 p.m., crews had rerouted some circuits to restore power to about two-thirds of those affected by of the outages, said Rice. Power was restored to all affected customers by 6:30 p.m.
The power outage at its height affected customers in Carmel, Corinna, Corinth, Dixmont, Etna, Exeter, Herman, Levant, Newburgh, Newport, Palmyra, Plymouth, St. Albans, Stetson, Detroit and Troy.
The malfunction of the substation in Detroit initially put others in Carmel, Corinna, Newport and Pittsfield out of commission, which is why the power outage was so widespread, said Rice, who was unsure when power would be restored to the remaining customers.
