Eversource has completed the first phase of a transmission project in New England that will accommodate more offshore wind energy.
Phase 1 of the Cape Cod Solution Transmission Program requires rebuilding of the regional electric grid to enhance resiliency and reliability of system for customers while supporting the infrastructure needed to connect offshore wind projects to the grid.
Phase 1 of the Cape Cod Solution is one of only two transmission projects underway in New England that will allow for the interconnection of offshore wind.
The Cape Cod Solution will enhance reliability for customers, make the system more resilient to storms and other extreme weather, and help meet the commonwealth’s and region’s decarbonisation goals while supporting the electrification of the transportation and heating sectors.
This co-optimised, multi-phase transmission programme involved several components, including the expansion of Eversource’s West Barnstable substation and the installation of an approximately 12.5-mile transmission line.
These lines are built with future electric and clean energy interconnection needs in mind, initially operating at 115 kV to immediately enhance service reliability for customers with the capability to increase capacity to 345 kV for the interconnection of clean energy from offshore wind farms as they come online.
“The Cape Cod Solution will deliver significant reliability and clean energy benefits to our customers, and we are excited to announce that the first phase of this groundbreaking project has been completed on time and on budget,” said Eversource President of Transmission and Offshore Wind Projects Bill Quinlan (pictured).
“In addition to building a more reliable and resilient transmission system in an area known for its vulnerability to severe weather, this project also establishes a strong foundation for interconnecting more clean energy resources to the electric grid.
“This approach underscores our commitment to minimising impacts to the environment and surrounding communities as we support the clean energy transition through our industry-leading infrastructure projects.”
As additional phases of the Cape Cod Solution proceed in the years ahead, Eversource will continue making transmission system upgrades to existing equipment and substations, recognising the amount of offshore wind expected to require interconnection.
Phase 1 of the Cape Cod Solution supported approximately 125 full-time employees and over 300 total employees, including members of the International Brotherhood of Electrical Workers (IBEW) Locals 104 & 223, Utility Workers Union of America (UWUA) Local 369 and Members of the Massachusetts Building Trades Council.
