Cogeneration System for Bellevue Hospital

Bellevue Hospital is a 1,500-bed hospital, psychiatric center, and Level 1 Trauma Center located on 1st Avenue on the east side of Manhattan. Part of New York City Health and Hospital Corporation’s (NYCHHC) network, Bellevue is one of the City’s largest full-service health care facilities and among Con Edison’s largest electric and steam customers.

Bellevue Hospital is a 1,500-bed hospital, psychiatric center, and Level 1 Trauma Center located on 1st Avenue on the east side of Manhattan. Part of New York City Health and Hospital Corporation’s (NYCHHC) network, Bellevue is one of the City’s largest full-service health care facilities and among Con Edison’s largest electric and steam customers.

Bellevue saw a compelling opportunity to implement a combined heat and power (CHP) system to provide cost savings, reliability and a more efficient energy operation for the hospital.  A prior feasibility study concluded that a reciprocating internal combustion engine-based CHP system – producing base load power 24/7 and supplying hot water to offset steam purchased from Con Edison – is both financially and technically viable. Cogeneration delivers real and demonstrable benefits by serving as proven power and thermal energy generation platform for healthcare campuses while also reducing total carbon emissions and improving power reliability.

Burns is completing 30% engineering, which will be used as the basis of the final project design for contractors to develop construction bids. Once complete, Bellevue’s cogeneration system will capture waste heat, and use it to supply various thermal loads including domestic hot water, space heating and reheat coils. Depending on further analysis, the heat may also be used to feed a 450-ton single-stage hot water absorption chiller.  Con Edison steam costs are relatively high and lowering steam purchases can present significant savings, so all options are being evaluated to make maximum usage of all available heat.

Cogeneration is expected to provide Bellevue with increased reliability, improved energy efficiency, and cost savings – a 6-7-year simple payback is projected based on an annual savings of $3.2 million.
