Why Are We Doing These Projects?

Both of these new lines will interconnect to existing substations in the area and will bolster system capacity and reliability on Martha's Vineyard to meet growing energy needs.

These projects will also help facilitate our efforts to decrease our carbon footprint by decommissioning the five existing diesel generators on the Island.

Where Is This Work Being Done?

Both projects will go through Falmouth and will come onshore to Martha's Vineyard in Oak Bluffs and Tisbury.

The work will be done in Falmouth and Martha's Vineyard (Tisbury and Oak Bluffs).

Martha's Vineyard Reliability Project

The proposed project will include the installation of a new 2.7-mile underground manhole (precast concrete vault) and duct bank system (a series of conduits that house electric cables).

The proposed route runs from the existing Falmouth Station on Stephens Lane to Jones Road, onto the Shining Sea Bikeway, down Mill Road to Surf Drive before transitioning in the Surf Drive parking lot to a submarine cable to cross Vineyard Sound.

The line will then travel 6.1 miles buried in the sea floor of Vineyard Sound before landing at East Chop, on Eastville Avenue where it will transition to onshore cables.

Once onshore, the line follows a new duct bank and manhole system along Eastville Avenue to an Eversource parcel.

The project will also include upgrades to the Falmouth Substation to support the installation of the new line and the installation of six pad-mounted transformers at the Eastville parcel to facilitate distribution of the new electric line feeding the Island.

91 Cable Replacement Project

The proposed project will follow the same duct bank and manhole system as the Martha’s Vineyard Reliability Project but will terminate at the Mill Road Parking Lot before transitioning to a 5.5-mile submarine cable to cross the Vineyard Sound and land at Eversource facilities in West Chop.
