UCMP Mystic to Everett Line Replacement

Español | Português Brasileiro| Kreyòl ayisyen (PDFs)

Why Are We Doing This Project?

To meet demand, deliver reliable energy and provide superior service to our customers, we are proposing to replace existing underground 115-kilovolt (kV) high-pressure fluid filled (HPFF) electric transmission lines with new cross-linked polyethylene 115-kv (XLPE) technology. Replacing the existing HPFF lines with XLPE cable technology will modernize cable infrastructure and increase long-term system reliability.

These improvements align with the Commonwealth's goal to achieve net zero carbon emission standards by 2050.  

The proposed project is part of a larger program we are conducting throughout our service territory in Massachusetts and Connecticut related to underground cable modernization. This project is a coordinated interconnection initiative between National Grid and Eversource.

  • Local and state permitting: 2023-2025
  • Proposed start of construction: Spring 2025
  • Estimated in-service date: Winter 2027

*Subject to change, pending necessary approvals
