Mayflower acquires interconnection queue position from Anbaric [free access]

June 3, 2021

Mayflower Wind—a 50-50 joint venture (JV) between energy companies Shell New Energies, US and the newly-formed US arm of Ocean Winds (a JV between EDP Renewables and ENGIE)—recently acquired a 1.2 GW interconnection queue position from independent grid operator Anbaric at the retired Brayton Point coal-fired power plant site south of Boston, Massachusetts. Mayflower Wind also announced that it would employ high voltage direct current (HVDC) offshore wind transmission technology for developments beyond the 804 MW capacity contracted with the state.


The deal further positions the JV to bid in the state’s present 1.6 GW tender and future rounds for an additional 2.4 GW of capacity. Massachusetts’ procurement structure now requires bundled generation plus transmission projects.


Particularly, Massachusetts and New England have a limited number of larger capacity interconnection points that are filling up as more offshore wind capacity is awarded and developers are rushing to tie their projects with those easiest and cheapest to access. The Brayton Point waterfront site, located 53 miles (85 km) south of Boston, is especially attractive because there is space onsite for a planned large HVDC converter station, 400 MW-plus battery storage and other infrastructure, along with an established transmission link to the Greater Boston area.
