NSTAR Transmission Upgrade Receives Approval from State

LCG, January 14, 2005--Yesterday the Massachusetts Energy Facilities Siting Board unanimously approved an earlier draft decision to accept NSTAR's proposal to construct a new, 345-kV electric transmission line designed to improve system reliability and capacity between generation facilities located in southeastern Massachusetts and Rhode Island, and loads in northeastern Massachusetts and the Greater Boston area.

The load area is now served by a single 345-kV line from the north, plus several low voltage line, and has limited options for competitively priced, electricity supplies.

The new, 18-mile, underground transmission line will extend from Stoughton to Boston and is estimated to cost $217 million. Project construction is planned to commence in early spring of this year, with the line in service by June 2006.
