With few outages occurring in its service territory during last week’s blizzard, PSNH sent 31 of its line crews, along with support teams and supervisory staff, to assist its Northeast Utilities sister company, NSTAR, in restoring power to tens of thousands of customers in communities on hard-hit Cape Cod. The New Hampshire team was based at NSTAR’s Yarmouth, MA service center, focusing on restoring power to customers in Harwich and Chatham.
