INTERCONNECTING IN BARNSTABLE

Avangrid is developing the Park City Wind project, which will deliver over 800 Megawatts of clean, affordable, and renewable electricity to the New England grid.

Park City Wind includes offshore wind turbine generators in Bureau of Ocean Energy Management (BOEM) Lease Area OCS-A 0534 along with associated offshore substation, offshore and onshore cabling, and onshore substation.

Park City Wind is currently engaged in permitting processes at the federal, state, regional, and local level and consulting with tribal groups and federal, state, and local agencies.

Avangrid is committed to responsible development, environmental protection, and minimizing impacts to Barnstable residents, businesses, and visitors during construction of all aspects of the proposed project.

Park City Wind proposes development of utility infrastructure necessary to deliver approximately 800+ MW of renewable wind power generated in federal waters to the ISO-New England (ISO-NE) regional power grid.

Components of the project located within the Town of Barnstable include:​

  • Installation of two cables through approximately 6.9 miles of state waters​

  • Approximately 4 miles of underground utility infrastructure, running from the landfall site (paved parking lot at Craigville Beach) to the proposed substation ​

  • A proposed substation located at 6 and 8 Shootflying Hill Road​

  • Approximately 0.7 miles of underground utility infrastructure from the proposed substation to the existing West Barnstable Substation, owned by Eversource​

  • New equipment at the existing West Barnstable Substation on Oak Street to facilitate the project’s interconnection into the ISO-NE electrical grid

HOST COMMUNITY AGREEMENT

In May 2022, Park City Wind entered into a Host Community Agreement with the Town of Barnstable for the Park City Wind project. The agreement represents a key milestone for the project and positions the Town of Barnstable to secure significant local benefits from the continued development of the U.S. offshore wind industry.

As part of the agreement, AVANGRID will pay the Town of Barnstable $16 million as a host community fee, above and beyond the applicable commercial and property taxes that will be assessed by the town. Additionally, AVANGRID will limit installation at Craigville Beach parking lot and along roadways to the non-summer months. Upon completion, AVANGRID will repave roadways and the parking lot at Craigville Beach, which will be used for temporary staging. AVANGRID has also committed to taking extra measures, above and beyond standard engineering practice, to protect groundwater in Barnstable at the site of the electric substation for Park City Wind.

In Barnstable, Park City Wind’s infrastructure includes subsea transmission cables buried beneath the seafloor, cables installed deep below Craigville Beach using trenchless methods, and duct banks buried beneath the Craigville Beach parking lot and public roadways to a substation connection at Shootflying Hill Road. To minimize short-term traffic impacts, AVANGRID is collaborating with the Town of Barnstable on their planned installation of a municipal wastewater line along the proposed route and defraying some construction costs for the Town.

Frequently Asked Questions:

  • Park City Wind builds upon and integrates with the thorough offshore siting analysis and extensive input from federal and state officials and many stakeholders done for the Vineyard Wind 1 offshore wind project.

    During the permitting of Vineyard Wind 1, it was agreed that there be a single corridor approximately 1,500 feet in width to lay the electric cables from all the projects in the lease area owned by Avangrid and its partner for the Vineyard Wind 1 project, Copenhagen Infrastructure Partners. This corridor is shown in the map below and calls for the cables to run from the lease area to the east of Muskeget Channel and to proceed to the north from that point. Using this single corridor minimizes disturbance to the seabed by avoiding laying cables in many different locations and directions in Nantucket Sound or other water bodies.

    Given this agreed upon corridor, Cape Cod is the appropriate general landing area and Barnstable is the optimal specific landing location. This is due to a second key fact—that the project needs to be able to connect to a substation to place the power into the electric grid. The existing Eversource substation in West Barnstable has the capacity to receive the 800+ Megawatts (MW) from the project and Park City Wind has the “queue position” to connect at this substation. This queue position means that Park City Wind is ahead in line of any other entity that would seek to use the capacity at this substation. There is no location on Cape Cod or any other coastal location in which Park City Wind has the option of connecting up to 800+ MW other than the existing West Barnstable Eversource substation.

    Given the substation location in West Barnstable, a landing in Barnstable is best because of the relatively short distance from the landing to the substation, and the presence of public roads under which the cables can be buried.

  • By working cooperatively with offshore wind projects, the Town of Barnstable and its residents gain numerous benefits, including leading the way on the fight to slow climate change and reduce harmful CO2 emissions.

    The Host Community Agreement between Park City Wind and the Town of Barnstable will provide significant funding to the town, but also ensures protections for town residents. Avangrid will pay the town $16 million as a host community fee, above and beyond the applicable commercial property taxes that will be assessed by the town. Avangrid has also committed to taking extra measures, above and beyond standard engineering practice, to protect groundwater in Barnstable at the location of its electric substation.

    In addition to being a leader in bringing clean energy to the region, Park City Wind’s mostly underground infrastructure will generate millions in property tax revenues for the Town of Barnstable while using few, if any, town services.

    Additionally, Avangrid will coordinate with the Town of Barnstable’s planned installation of a municipal sewer line along the onshore route to minimize disruption and defray some of the town’s sewer line roadwork costs.

  • Park City Wind is currently engaged in permitting at the federal, state, regional, and local level and is consulting with tribal and local agencies. You can learn more about these permits here.

  • No. The offshore wind turbines will be located in federal waters over 35 miles from Barnstable’s coastline. They will be located in a federally designated wind lease area on the outer continental shelf south of Martha’s Vineyard and Nantucket.

  • No, Avangrid will continue to coordinate closely with the Town of Barnstable on the planned installation of a municipal sewer line along the onshore route to minimize disruption and defray some of the Town’s sewer line roadwork costs. Further, Avangrid will work with the Centerville-Osterville-Marstons Mills Water District on water main relocation and replacement as needed. Avangrid will plan its duct bank instillation around existing National Grid gas lines.

  • For all Avangrid offshore wind projects, it is preferable to stage construction at an existing, large parking lot at a public beach; a large parking lot is especially needed to stage the heavy equipment needed for the horizontal directional drilling operation which allows for cable vaults to be placed approximately fifty feet below the beach and land under the paved parking lot. By using a parking lot, which is connected to public roadways, Avangrid significantly reduces potential damage to coastal resources.

    Avangrid has completed three separate siting investigations for landings in Barnstable, first for Vineyard Wind 1, second for Park City Wind, and third for Commonwealth Wind. The first siting analysis determined that Covell’s Beach was an optimal location, and it was selected for Vineyard Wind 1. That beach could not also accommodate the Park City Wind project, and hence Craigville Beach was selected for the second project, due to the large parking lot and connection to public roadways for cable placement. There is no comparable site with these characteristics.

  • No. By using trenchless Horizontal Directional Drill (HDD) methods, cable casing pipe installation begins from the parking lot and tunnels underneath the beach to a depth of approximately 50 feet at the tideline to a point approximately 1000 feet offshore. This minimizes disturbance to the beach or the nearshore area. Deep and permanent burial inside a casing pipe under the beach will also mean that the cables pose virtually no risk of exposure, especially given Craigville Beach is a stable accreting beach (the opposite of eroding).

    During installation, a portion of the western part of the Craigville Beach parking lot will be temporarily fenced off and excavated to install the transition vaults underneath the parking lot and install the cable casing pipe deep under the beach.

  • Yes. Craigville Beach is a large beach and Avangrid will only fence off and be located in the western end of the parking lot. The eastern end of the lot will remain open as will the beach, unless Town or state officials direct otherwise.

  • Park City Wind will have onshore utility infrastructure on the below roads; an interactive map of this route can be found above on this webpage.

    • Craigville Beach Road

    • Main Street

    • Old Stage Road

    • Shootflying Hill Road

  • Upon completion, the parking lot and roadways will be repaved in a full curb to curb restoration at no cost to the town. There will be manhole covers in the roadway and manhole covers in the Craigville Beach parking lot for utility access.
