Under a 13-year contract, NRG will provide services from its Combined Heat and Power Plus (CHP Plus) programme that integrates conventional energy sources and leverages them with efficiency and environmental technologies. The hospital will use electricity from a combined heat and power system that includes the production of steam for heating and chilled water for air conditioning, achieved by means of a thermal energy storage system. Other green elements include solar power generation and energy-saving smart meters, as well as and backup power.

Barry Rabner, president and CEO of Princeton HealthCare System, said: “NRG’s proposed CHP Plus program enables us to use environmentally sustainable energy as we fulfill our mission of providing high-quality health care. NRG will fully meet our hospital’s energy needs while reducing our operating costs and protecting the environment.”

David Crane, president and CEO of NRG Energy, said: “We’re honored to be part of Princeton HealthCare System’s team as they bring this new state-of-the-art hospital with advanced, energy efficient systems to the Princeton area. Our joint effort with Princeton HealthCare has been made possible by the effective implementation of a far-sighted state energy policy as reflected in New Jersey’s Energy Master Plan.”

The structural elements of the CHP system are subject to Plainsboro Township Planning Board approval, since such a power generating system was not initially part of the Plainsboro site plan approval of the hospital project.
