A manhole explosion at approximately 10 p.m. on Hittinger Street is responsible for plunging most of Belmont into the dark, according to Belmont Light, the municipal electrical utility.

The explosion and subsequent fire “caused the entire west side of town to lose power,” read a message on the utility’s Facebook account. While power remained on in the southeast section of Belmont and along Belmont Street and Trapelo Road into Cushing Square, all other neighborhoods and streets were dark. The resulting loss of electricity left most homes without power, street lights to go out, and resulted in drivers negotiating intersections without traffic signals.

Belmont Light said it has crews at the location, which is nearby to one of its transformer stations.

“We are ensuring that line workers can safely enter the manhole before determining the extent of the damage. We will provide an update ASAP,” the posting read.

UPDATE: At approximately 11:31 p.m., Belmont Light reported it had identified a failed cable and are testing others in an attempt to isolate the issue.

“We hope to start to pick customers back up within 30 minutes [at midnight, March 19] and will be making progress to restore power for all customers following testing.”

UPDATE: Belmont Light has completed the work bringing power back to the town.

At approximately 8:15 p.m. on Monday, July 9, a fallen tree branch struck Belmont Light electrical wires, resulting in a large power outage affecting customers in the eastern section of town, adjacent with Cambridge.

Approximately 2,000 customers were initially without power in the area east of Common Street. The Belmont Light Operations Team worked quickly to assess the damage and determine a course of action. By 9:10 p.m., power was restored to approximately 1,500 customers, with 500 customers in the Winn Brook area awaiting restoration as Belmont Light made necessary repairs to its system. By 10 p.m. repairs were completed and power was fully restored to all customers.

Belmont Light credits a customer on Lodge Road for spotting the fallen tree branch, which caused a series of events to occur, ultimately shutting down four feeder cables. The customer posted their observation on Belmont Light’s Facebook page, allowing the Operations Team to pinpoint the problem in an efficient manner. 

“We encourage all of our customers to contact us when they see a problem like a fallen tree,” said Chris Roy, Belmont Light General Manager. “Whether it’s a phone call, a social media post, or some other method, the communication allows us to get power restored quicker so that we can better serve all of our customers.”

“Belmont Light thanks customers for their patience during the repair work. At this time, Belmont Light does not foresee any additional issues to arise.”

Correction: In an earlier version of this story, the date of the disruption was noted as Monday, June 9. The correct date was Monday, July 9.
