 customer demand for power, and strengthen the electric grid's resilience against extreme weather and other safety and security threats.  In Connecticut, Massachusetts and New Hampshire, our transmission projects include transmission line upgrades, the installation of new transmission interconnection facilities, substations and lines, and transmission substation enhancements.

Greater Cambridge Energy Program:  The Greater Cambridge Energy Program will construct Eversource’s first underground transmission substation in Cambridge, Massachusetts, along with associated transmission and distribution lines.  The project will address the increased electric demand in the region, enhance the resiliency of the transmission system, and ensure a flexible grid to reliably serve customers.  The flexibility to transmit and distribute mixed energy sources will support the decarbonization and electrification goals of both the City of Cambridge and the state of Massachusetts.  The new 115/13.8-kV, 35,000 square foot substation will be located in an underground vault and includes three distribution power transformers supplying thirty-six distribution circuits.  The project also includes five underground duct banks housing eight new 115-kV transmission lines.  The Massachusetts Energy Facilities Siting Board approved the project on June 28, 2024.  Additional required environmental permits are expected to be approved by the end of 2025, as well as a license from the MA DEP expected to be approved by the end of the second quarter of 2026.  The initial in-service date for the project is June 2029, which includes two 115-kV transmission lines and the transmission portion of the substation.  The first distribution circuits and substation distribution will be placed in-service by the end of 2029.  The remaining transmission and distribution circuits will be placed in-service throughout 2030 and into 2031.  The total estimated project cost is approximately $1.84 billion, with $1.38 billion allocated for transmission and $460 million for distribution.  As of September 30, 2025, $159.1 million has been spent on the project, with $120.0 million for transmission and $39.1 million for distribution.
