Raising the Elevation of a Substation

When an area of South Boston, Massachusetts, near the harbor started bustling with businesses and living spaces, Eversource Energy took notice, but wondered how to expand in a crowded urban space. And how could it prevent outages in an area where flooding and storm damage posed significant risk? To find answers, the utility looked up.

Coastal Expansion Risks

Eversource (named NSTAR at the beginning of the project) proposed a new 115kV electrical substation called Station 99 to be built on Seafood Way in Boston. As the street name suggests, it’s near the harbor. In fact, the proposed site was a network of fishing piers and a U.S. Navy base that was filled in, and it is in a designated Special Flood Hazard Area (SFHA).
