About South Boston Power Plant

776 Summer Street, South Boston, Boston, MA

Proposed 1.93 million square foot, 15.2-acre mixed-use development featuring 1,344 residential units, 368,070 square feet of office space, a 344-key hotel, and 85,630 square feet of retail and restaurant space, in addition to 1,397 above-and-below-grade parking spaces.

Updated plans submitted in July 2019 call for the total square footage to be reduced to 1,780,000. Residential units have been decreased to 750 total and office space increased from to 470,000 square feet. Retail space planned is down slightly to 81,200 square feet. 330,000 square feet of R&D/Lab space has been added to the proposal along with 14,000 square feet of civic/cultural space. 

The development would replace and incorporate an existing former Edison power plant. Eight new multi-story buildings would be constructed; four buildings would be 170 feet high and taller. Three architecturally-significant former turbine halls that run end-to-end through the site’s center would be rehabilitated and would be the development’s “heart and soul”. Local retail and other amenities would be located on buildings' ground floors. The proposed development would be LEEDv4 sustainability certifiable.

Multiple new pedestrian connections would be created between the development and the surrounding streets, creating a new link between South Boston and the Reserved Channel waterfront. 1.15 acres of waterfront public space would be created along the Reserved Channel; the space would celebrate the working port’s heritage. A number of indoor and outdoor spaces would be devoted to the arts, creating an “arts and industry” district for artists and other creative individuals.

The project site is located at the corner of First and Summer Streets in South Boston, steps to East Broadway and near Boston's Innovation and Design Building. Downtown Boston and the Seaport District are a short drive or bus ride away. Construction of the proposed development would occur over the next 10 to 15 years. The development’s first phase, which would include demolition of existing buildings, preservation of turbine halls and construction of new housing along East First Street. The industrial power plant site would be fully decommissioned and cleaned.

The development program would construct eight new buildings and rehabilitate the three turbine halls.
