Upgrades reduce energy and maintenance costs, and reduce greenhouse gas emissions 

Additional improvements, which will upgrade the lining of the zoo’s heating pipelines to extend the useful life of the existing infrastructure, are expected to be complete in winter 2025 

The Department of Citywide Administrative Services (DCAS), the New York Power Authority (NYPA), and the Wildlife Conservation Society (WCS) announced the completion of mechanical work to the heating system at the Bronx Zoo, marking a significant upgrade to the beloved zoo’s infrastructure. The upgrade to the zoo’s cogeneration power plant – which provides heat to several facilities across the campus – will reduce energy and maintenance costs by nearly $500,000 annually in city operations, reduce greenhouse gas emissions by 3,100 metric tons, and help future-proof the zoo for decades to come. Additional improvements, which will upgrade the lining of the zoo’s heating pipelines to extend the useful life of the existing infrastructure, are expected to be complete in winter 2025. 

Some of the buildings at the Bronx Zoo supported by this heating system include JungleWorld, Congo Gorilla Forest, Carter Giraffe Building, World of Birds, Reptile House, Zoo Center, and various additional buildings across the zoo. 

“Today’s collaboration between DCAS, NYPA, and WCS marks a significant milestone in our commitment to sustainability and conservation citywide,” said DCAS Commissioner Dawn M. Pinnock. “The upgraded heating system at the Bronx Zoo not only enhances the comfort of staff, visitors, and wildlife, but is also a powerful example of how strategic partnerships can drive tangible environmental impact. This initiative not only reduces energy costs but also underscores our dedication to reducing greenhouse gas emissions, advancing New York’s environmental goals for a cleaner, greener future for all, including our furry, scaly, and feathery friends.” 

“The Bronx Zoo, one of New York’s most-cherished institutions, continues to further its legacy of conservation and sustainability with a suite of energy efficient improvements,” said New York Power Authority President and CEO Justin E. Driscoll. “The Power Authority and New York City have partnered on important energy efficiency projects for decades and these upgrades to the zoo’s cogeneration power system are the latest of those impactful efforts, significantly reducing the zoo’s carbon footprint and energy costs, while simultaneously improving overall system reliability.” 

“I can’t stand the thought of giraffes, monkeys, and lizards enduring a New York winter without heat, so I applaud this partnership between The Bronx Zoo, DCAS, and the New York Power Authority to invest in the zoo’s heating systems,” said NYC Cultural Affairs Commissioner Laurie Cumbo. “The city is proud to partner with cultural institutions in all five boroughs to address their critical infrastructure needs that can often be more difficult to fundraise for than other high-profile projects. This is a great example of how the public and private sectors can collaborate to make sure New Yorkers have access to world-class cultural facilities, and that our non-human neighbors can keep their flippers warm all year long.” 

The enhanced heating system, overseen by DCAS, is part of the agency’s citywide efforts to improve the city’s quality of energy, reduce costs, and increase electrical efficiency as well as reliability. At the Bronx Zoo, this new system’s impact includes slashing greenhouse gas emissions, approximately equal to the annual electricity use of 4,082 homes or the consumption of 6,834,330 pounds of coal (or 3,100 metric tons of greenhouse gas reductions). Greenhouse gas emissions play a role in climate change and contribute indirectly to severe weather events such as flooding and air pollution. 

Through partnerships with the Power Authority and the engineering- architecture firm Ramboll, DCAS is implementing a new $17 million heating system at the Bronx Zoo. This project helps create energy efficiency by replacing the cogeneration plant’s pumps, waste-heat recovery units, fluid coolers, and controls. NYPA has also installed an energy management system to oversee the plant as part of the project, and rehabilitated some of the zoo’s water infrastructure, ensuring reliable delivery of hot water from the cogeneration system to 13 of the zoo’s buildings. 

The project advances environmental goals of New York State’s Climate Leadership and Community Protection Act, New York City’s Climate Mobilization Act, and New York City’s Local Law 97, which calls for a 50 percent reduction in government operations carbon emissions by 2030. 

The Bronx Zoo is a member of the Cultural Institutions Group, a group of 34 cultural organizations located on City-owned property administered by the Department of Cultural Affairs, which receive significant capital and operating support from the City to help meet basic security, maintenance, administration and energy costs. In return for this support, these institutions operate as publicly-owned facilities whose mandate is to provide cultural services accessible to all New Yorkers.
