Tri-Generation is powered by natural gas, the cleanest of all conventional fuel sources; this decreases emissions and the hospital's carbon footprint-a reduction equivalent to removing the carbon that would be absorbed by 2,244 acres of forest and produced by 1,799 cars annually, reports Robert Peake, Director of Facilities, Construction, and Real Estate for Atlantic Health.
Although Tri-Generation does not completely eliminate Overlook's need for a power company, the system does provide two-thirds of the hospital's power.
"The hospital requires 3.5 megawatts of power.
makes 2 megawatts continuously, but we could make more," says Peake
also creates the ability to "island" the hospital in the event that the power company cannot produce electricity, enabling Overlook to use all of its usual resources completely independently of the public power grid.
In the past, we could not do this, Peake
The move to Tri-Generation makes environmental sense, and fiscal sense too.
The $5.3 million project will yield a return on investment in just 2.25 years-and that's even before taking into consideration a $1 million grant from the Bureau
of Public Utilities plus a $250,000 grant for ancillary equipment.
"By comparison," says Peake
, "when we looked at solar power as an alternative, it would have taken 25 years to achieve a return on our investment.
"The black roof helps conserve heat," explains Peake
, "so we use less energy."
"Overlook, like all hospitals, uses a lot of resources, but we do so responsibly," says Peake
