Power is back on for all customers, Hydro One announced this afternoon.
More than 8,800 Hydro One customers from Chelmsford to Lively found themselves without power this morning.
The power outage happened at about 8:50 a.m., said Nancy Shaddick, a communications officer with Hydro One.
Crews have been dispatched to restore power. They are working on the conductor that serves those customers. The cause of the outage is still unknown.
"Our first priority is to restore the power," Shaddick said. "Crews are doing that as quickly as possible."
The estimated time or restoration is noon.
