The seven engine generators installed on the midtown Manhattan hotel’s roof overlooking West 53rd Street generates 1.75 MW of clean electricity and 2.7 MW heat for building operations. This satisfies over 50 percent of the electricity demand and 35 percent of the steam demand for the 1,981 guest rooms, Anaergia says.
The electricity and steam heating from the system is expected to reduce the carbon footprint of Hilton New York – the city’s largest hotel (pictured) – by more than 30 percent or 10,000 metric tons annually. The system is also expected to reduce operating expenses of the building by nearly half a million dollars each year over the 20-year life of the contract.
Anaergia designed, built, owns and now operates the clean energy system. Anaergia’s distributed energy system meets criteria for the US Department of Energy’s ITC program that aims to promote electrical efficiency and conservation of resources through combined heat and power systems. Similarly, the project also qualified for the New York State Energy and Development Authority program that aims to support the energy, economic, and environmental well-being of New York State.
The hotel also features a 16,000-sq-foot green roof system installed by Xero Flor America on the building’s fifth floor rooftop setback – the same place as the cogeneration system. The green roof supports local farming and plays host to locally grown plants harvested from an upstate New York farm, Hilton says. The hotel also features a fuel cell atop the building’s fifth floor roof for which it was awarded the 2008-2009 Environmental Recognition Program “Green Street” Award by the Avenue of the Americas Association.
In October, FuelCell Energy and Inland Empire Utilities Agency brought online a 2.8 MW fuel cell power plant owned by UTS Bioenergy/Anaergia. The electricity and heat will be sold to IEUA under a 20-year power purchase agreement to provide almost all of the baseload power need of a wastewater facility in southern California. On-site wind and solar arrays installed by IEUA provide the rest of the facility’s power needs.
