Project Information

The Company has filed petitions for approval to construct approximately 27.5 miles of electric transmission lines offshore in Massachusetts state waters (passing through state waters in the Towns of Nantucket, Edgartown, Tisbury, Oak Bluffs, and Falmouth) and onshore in the Town of Falmouth, at voltages between 200 and 345 kilovolts (“kV”), along with a new substation in the Town of Falmouth (“Onshore Substation”) (the “Project”).  The purpose of the Project is to connect The Company’s proposed offshore wind energy generation resource (the “Offshore Wind Resource”, also referred to by the Company in its petitions as the “Clean Energy Resource”), located in federal waters, to the regional transmission system in New England.

The Company’s proposed Project consists of (1) electric transmission lines offshore in Massachusetts state waters (passing through state waters in the Towns of Nantucket, Edgartown, Tisbury and Oak Bluffs, and Falmouth); (2) electric transmission lines onshore in the Town of Falmouth, including two potential landfall sites; and (3) a new substation in the Town of Falmouth.  The purpose of the Project is to connect the Company’s Offshore Wind Resource to the New England electric grid.

The Company’s filing identifies an offshore Export Cable Corridor (“ECC”) for the offshore portion of the Project, two primary alternatives for the onshore route (the “Proposed Route” with one potential variant to the route, and the “Noticed Alternative Route” with three potential variants to the route), and two primary alternatives for the Onshore Substation location.  A final approved route could include a combination of segments of the Proposed Route, the Noticed Alternative Route, and/or their variants.

Siting Board Statues and Regulations

The Company’s three petitions have been consolidated for hearing before the Siting Board under docket number EFSB 21-03/D.P.U. 21-142/21-143.  Under G.L. c. 164, § 69J, the Siting Board will review The Company’s filing to determine whether the Project would provide a reliable energy supply for the Commonwealth with a minimum impact on the environment at the lowest possible cost.  Under G.L. c. 164 § 72, the Siting Board will determine whether the proposed Project is necessary for the purposes stated, serves the public convenience, and is consistent with the public interest.  Under G.L. c. 40A, § 3, the Siting Board will determine whether the requested zoning exemptions in Falmouth are required for the Project and whether the present or proposed use of the land or structures is reasonably necessary for the public convenience or welfare.

The Siting Board will not review the Offshore Wind Resource itself (including the turbine array, related equipment, and a portion of the transmission line) as it is located in federal waters and therefore is subject to federal jurisdiction and review.
