Around 12,800 Eversource customers throughout the Monadnock region lost power Monday evening due to an equipment failure at the company’s substation in Troy. 

Kaitlyn Woods, a spokesperson for Eversouce, said Tuesday afternoon that power was returned to all customers affected by the outage by 7 p.m. on Monday.

Outages occurred in Dublin, Sharon, Marlborough, Fitzwilliam, Richmond, Nelson, and Harrisville with the highest percentages of outages occurring in Rindge, Jaffrey, Peterborough, and Troy.

“A device failed unexpectedly at the substation around 4:50 p.m.,” said Woods, who didn’t elaborate further on what specifically failed.

A substation, according to Woods, is a part of the electrical distribution system that helps to regulate the voltage to a level that can be transmitted safely to homes. Eversource has 170 substations throughout the state. 

The company was able to restore power to more than 4,000 customers within five minutes of the outage using smart switches, a technology that allows Eversource to redirect electricity from another source. The switches are controlled from a system operations center in Manchester. 

Eversource was working at the substation – located on Monadnock Street – throughout the day Tuesday. Woods said repairs are expected to be complete by the end of the day.
