Boston Medical Center Carbon Neutral Campus

Boston, Massachusetts

Boston Medical Center’s (BMC) main objectives for a cogeneration plant was to reduce energy cost, reduce their carbon footprint and to increase the resiliency of their inpatient care buildings, totaling 1.5 million square feet during a major campus consolidation effort. A single 2 Megawatt internal combustion engine cogen system offered BMC the best return on investment and enough power to keep their most critical inpatient care buildings energized and heated in the event of an extended normal electric power outage or other catastrophic event. This cogen system provides $1.5M of annual operating savings.

Resiliency features such as the cogen and enhanced 15kv switching were implemented. With this system, all waste heat is utilized during summer months for air reheating as well as domestic water heating significantly reducing BMC’s energy footprint. CMTA also helped BMC obtain large incentives from the local utility company and the Mass Department of Energy Resources which reduced the first cost of the project by $5.0 million.

As significant energy reductions are a cornerstone goal for BMC, so is carbon neutrality. As a result, BMC engaged in the largest collaborative power purchase agreement (PPA) in the United States. 16 megawatts of the 60 megawatt solar field is allocated to BMC to make BMC a zero-energy campus. Through the cogen, PPA and the campus consolidation strategies, BMC has reduced their carbon footprint by 90% since 2011.

CMTA’s knowledge and attention to detail made this difficult project a major success with energy savings of $1.5M. Thanks to their expertise, we have the most resilient hospital cogen plant in Boston.
