Description:

Abstract:: These data represent the priority 345-kilovolt (kV) substations in Massachusetts or Rhode Island identified in the Massachusetts Clean Energy Center (MassCEC) "Offshore Wind Transmission Study Final Report." In the spring of 2014, MassCEC, working in close coordination with the Executive Office of Energy and Environmental Affairs, the Massachusetts Office of Coastal Zone Management, and the Massachusetts Department of Energy Resources, commissioned a study on the components and aspects of transmission infrastructure and regional electric grid interconnection associated with potential wind projects offshore Massachusetts. The study report developed by a team of consultants led by the ESS Group Inc. provides important insight into the technical and logistical aspects of transmission. The study affirms that there are a number of potential interconnection points in Massachusetts and southern New England where offshore wind projects in the Massachusetts Wind Energy Area (WEA) and the Rhode Island/Massachusetts WEA could link into the existing electric grid. These Independent System Operator-New England 345- kV substations could integrate the large block of energy generated by potential offshore wind projects with certain upgrades and improvements. Analysis contained in the study indicates that the three most advantageous interconnection points, based on a number of criteria, are the following: Brayton Point Substation in Somerset, MA; Canal Substation in Sandwich, MA; and Kent County Substation in Warwick, RI. (Other potential interconnect points include: Carver Substation in Carver, MA; Oak Street Substation in Barnstable, MA; State Forest Transition Station at Myles Standish State Forest, MA; Millstone Substation, Waterford, CT; Montville Substation, Montville, CT; and Shoreham Substation, Brookhaven, NY). Of the three top-tier substation sites identified in the study, only one—Canal Substation in Sandwich—would involve a potential route within the Massachusetts Ocean Management Planning Area. The MassCEC transmission report is available at: <http://images.masscec.com/uploads/attachments/2014/10/MassCEC-OSW-Transmission-Study-2014.pdf>.
Purpose:: These data were used in the development of the 2015 Massachusetts Ocean Management Plan.
Supplemental_Information:: The Massachusetts Ocean Management Plan protects critical marine habitat and important water-dependent uses and sets standards for new ocean-based development. In response to the Oceans Act of 2008, the Executive Office of Energy and Environmental Affairs (EEA) issued the original ocean plan in December 2009. The Oceans Act requires EEA to review and update the ocean plan at least once every five years. The 2015 Massachusetts Ocean Management Plan, released on January 6, 2015, is the first formal amendment to the 2009 ocean plan. These data were produced to support the development of the 2015 ocean plan.
