Cape Cod Solution Phase II
Why Are We Doing This Project?
This project is the second phase of the Cape Cod Solution Program, a group of projects designed to improve the reliability of the electric system serving the Southeastern Massachusetts and Greater Cape Cod areas both today and in the future as more clean energy resources like offshore wind are connected to the grid.
Where Is This Work Being Done?
The second phase of this program will increase operating voltage of a new transmission line from 115-kV to 345-kV, which is necessary for an offshore wind generator to be able to connect to our system. This change in operation will not result in any noticeable changes to the transmission line along the 13-mile project route.
In order to support the increase in voltage, additional facilities will need to be constructed at each end of the new line at the Bourne Switching Station, located on Joint Base Cape Cod, and the West Barnstable Station.
Bourne
A new 345-kV station is planned to be built in Bourne adjacent to the existing station. All work will be within Joint Base Cape Cod.
Barnstable
A 345-kV switchyard is planned to be built on the Eversource-owned site of the existing West Barnstable Station on Oak Street.

Community Outreach
We will continue to engage with town officials, residents, businesses, community groups and other stakeholders through municipal briefings, door-to-door outreach, site visits, and additional meetings as needed – answering questions and listening to concerns about the project. We will also maintain an active field presence during construction.
Please read our Cape Cod Solution Phase II frequently asked questions for answers to common questions and concerns we've received during our outreach efforts.
Siting Review
Through the EFSB/DPU process public and other interested stakeholders were given the opportunity to participate through the EFSB-sponsored public hearing. Owners of property abutting and near the project were informed of the EFSB Public Comment Hearing being held on November 14, 2023.
On February 28, 2023, we filed the below documents with the EFSB and DPU for approval to construct and operate Phase II. All files are PDF format.
