Eversource has completed Phase I of the Cape Cod Solution, New England’s largest transmission project for offshore wind development. This initiative enhances system reliability and resilience while supporting decarbonization and electrification goals.
Key components of the project include expanding the West Barnstable substation and installing a 12.5-mile transmission line. Initially operating at 115 kV, these lines can upgrade to 345 kV for future offshore wind energy enabling the integration of power from offshore wind farms.
“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. “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.”
Phase 1 involved 125 full-time employees and over 300 workers, including union members. Future phases will continue to upgrade the transmission system to support more offshore wind energy.
