Eversource Constructing Substation on Seafood Way in South Boston

The project includes the construction of underground distribution and transmission line segments, connecting the new substation to our existing infrastructure.

The South Boston Waterfront is the fastest growing urban area in the Commonwealth – with 10 million square feet of development built between 2000-2013, and another 17 million square feet planned over the next two decades.

Recognizing this significant growth and rapid business and residential development, Eversource is constructing a major new electrical substation on Seafood Way in South Boston. The project includes the construction of underground distribution and transmission line segments, connecting the new substation to our existing infrastructure.

If a catastrophic, Hurricane Sandy-like storm were ever to hit Boston’s waterfront, the new substation would be in less danger as its being built on piers to protect it from flooding. We've driven mini-piles 80 feet into existing bedrock and are now pouring the concrete foundation, with beams and columns to follow. According to Project Manager Mike O’Malley, structural steel will keep the substation 15 feet above ground level. 

The Seafood Way substation is one of many projects across Eversource’s Bay State service area focused on improving electric system reliability. The South Boston project establishes a foundation to serve the area’s anticipated increased electrical needs as development in the Seaport district continues to grow. We expect construction on the substation to be substantially complete by December 2017, followed by tie-ins to the underground transmission system.
