Clean on-site energy supply company American DG Energy Inc has signed agreements to provide green energy solutions to The Forest Hills, a 120-unit housing co-operative, located in Queens, New York, US. American DG is to install a 100 kW CHP energy system and a 200 tonne natural gas engine driven chiller at the property. The value of the deals to American DG Energy is $2.81 million.
The company is installing a new chiller to replace a 45-year old steam chiller, which was both costly to run and an inefficient provider of chilled water and space cooling for the property. The new gas engine driven chiller will generate more chilled water, allowing The Forest Hills also to decommission two old steam boilers, which already at the end of their useful life.
Instead of purchasing the new chiller, The Forest Hills opted for an ‘on-site utility’ arrangement by American DG, under which The Forest Hills will pay only for the energy it uses and will avoid additional operating costs. American DG Energy will handle all service, maintenance and repair.
In addition to installing the chiller, American DG Energy is installing a 100 kW CHP system to provide electricity and hot water for space heating and domestic hot water use. The Forest Hills opted to purchase the CHP system, but has selected American DG Energy to operate and maintain it.
