BOSTONAvangrid Inc. says that it recently joined local officials to participate in a ribbon cutting for Eversource’s Cape Cod Solution Phase 1 grid upgrade in Bourne, Massachusetts. 

As part of its New England Wind 1 project (formerly the Vineyard Wind South project), Iberdrola subsidiary Avangrid provided more than $13.7 million in critical funding for grid upgrades through the Transmission Support Agreement and Large Generator Interconnection Agreement with Eversource. 

The grid upgrades are designed to support enhanced reliability and resiliency on Cape Cod while providing the necessary infrastructure for the project to deliver power across the region. 

The New England Wind 1 System Impact Study identified the uprate to 345kV of a 115kV transmission line connecting the Bourne Switching Station and the West Barnstable Substation as a necessary grid upgrade. 

With more than $13.7 million in funding from Avangrid, the line was converted into a 345 kV line, running from the Bourne Substation to the West Barnstable Substation. The new line will be initially operated at 115kV until the 345kV GIS substations at Bourne and West Barnstable are built as part of Phase II of New England Wind 1’s grid upgrades. 

With increased capacity and additional planned upgrades, the Cape Cod electric grid is expected to realize significantly enhanced reliability and resiliency from investments supported by New England Wind 1. 

New England Wind 1 is located in federal lease area OCS-A 0534, roughly 30 miles south of Barnstable, Massachusetts and making landfall under the Craigville Beach parking lot. The project will border Vineyard Wind 1 to the south.

Avangrid says that if the New England Wind 1 project is selected in the current competitive procurement, the project can begin construction as soon as next year and achieve commercial operations before the end of the decade.
