BOSTON (MyFoxBoston.com) - The power is back on for thousands in the Back Bay. Overnight, NStar crews cut power to about 12,000 customers so they could repair a transformer which failed early Sunday morning.
The problem involved the Scotia Street substation, near the Hynes Convention Center.
FOX 25 cameras were rolling as the lights came back on Monday morning. The lights were out from 1 a.m. until around 4:25 a.m.
It took NStar nearly nine hours to restore power to the neighborhood Sunday. The outage also caused a massive traffic jam on the Mass. Pike with cars stopped from Newton to Boston. The reason was that state police had to shut down the Prudential Tunnel because there were no lights and no way to circulate air in the tunnel. It was also shutdown overnight, but was re-opened about at 5 a.m.
NStar's president is blaming the mess on an equipment failure. The Scotia Street Station is the same one that caused a blackout in the Back Bay last March. Power was out for several days during that outage.
"We had what appears to be a cable fault failure. That caused the transformer to come out of service," NSTAR President Craig Hallstrom said.
Approximately 12,500 NSTAR customers were without power in May 2012 after an issue at the same Scotia Street substation. The 2012 outage impacted the Prudential Complex and the surrounding neighborhood, including Beacon Street and Huntington Avenue.
A fire also broke out at the substation in March 2012.
