The Massachusetts portion of GSRP, under consideration by Massachusetts regulatory officials, includes 23 miles of overhead 345kV line and related 115kV transmission system upgrades. A decision on the Massachusetts portion of the project is expected later this year. The total cost of the project is estimated to be $714m.

According to CL&P, the new transmission project will improve electric system reliability and enhance customer access to cleaner, competitively priced energy sources.

Kathleen Shea, project director of CL&P, said: “The Council’s recent decision on GSRP paves the way for construction of a new transmission line to move power more reliably around the area, relieving constraints and eliminating transmission line overloads.

“The project will also create another path for delivering power into the Springfield area and Connecticut from other New England states, encourage competition among suppliers, enhance fuel diversity, and allow better access to lower-cost and renewable energy resources – all of which are critical to the region’s economic health.”
