Eversource and National Grid Complete Major Upgrade to New England’s Electric System

HYANNIS – Cleaner, competitively priced electricity now has a new way to reach customers in southern New England.

Eversource and National Grid partnered on the $483 million Interstate Reliability Project.

The project includes station upgrades and the installation of a new 345 kilovolt transmission line along 75 miles of rights of way in Connecticut, Massachusetts and Rhode Island.

The new line and related improvements are expected to enhance reliable delivery of power to customers throughout New England and strengthen the regional electric grid.

“The Interstate Reliability Project improves the efficiency of the grid by eliminating system bottlenecks and improving the flow of power within our region,” said David Boguslawski, Vice President of Transmission Strategy and Operations at Eversource. “The project also supports the region’s economic growth and environmental goals through greater access to newer, more efficient and cleaner generating plants.”

Along with the system reliability and environmental benefits, the IRP will also produce millions of dollars of new, annual property tax revenues to 18 municipalities in the three states where the project was constructed.

Eversource provides power to Cape Cod and Martha’s Vineyard and National Grid provides power for Nantucket.
