Avangrid Celebrates Cape Cod Solution Grid Upgrades


Avangrid joined in a ribbon cutting for Eversource’s Cape Cod Solution Phase 1 grid upgrade in Bourne, Mass. 

As part of its New England Wind 1 project, Avangrid provided funding for grid upgrades through the Transmission Support Agreement and Large Generator Interconnection Agreement with Eversource. 

As part of the updates, the transmission line was converted into a 345 kV line, running from the Bourne Substation to the West Barnstable Substation. The new line is set to be initially operated at 115 kV until the 345 kV GIS substations at Bourne and West Barnstable are built as part of Phase II of New England Wind 1’s grid upgrades.

“As the most advanced offshore wind opportunity in the region, New England Wind 1 is already delivering significant benefits by supporting critical grid upgrades on Cape Cod that will not only provide a transmission backbone for the project, but deliver a more reliable and resilient electric system,” says Avangrid CEO Pedro Azagra. 

“Our experience constructing Vineyard Wind 1 makes clear how important it is to have the onshore infrastructure in place to deliver the clean power from offshore wind. The completion of these Cape Cod Solution Phase 1 upgrades, along with future investments through our Transmission Support Agreement, moves New England Wind 1 even closer to delivering power before the end of the decade.”
