A 12-ton clean energy cogeneration system, a heat and power plant that is central to Beth Israel Medical Center’s Go Green project, was hoisted by crane to the roof of the Kings Highway Division in Brooklyn recently.
The natural gas-fired cogeneration unit is housed within a 20-by-8-by-8-foot container. Project contractor Ecosystem Energy Services Inc. estimates that the unit can generate enough electricity to help reduce the hospital’s dependency on electrical utilities by 40 percent.
Central to the $4.1 million project — half a million less than the original estimated cost — is the conversion of the hospital’s heating network from steam to hot water. The network will use recycled heat generated by the cogeneration system to heat the building.
The project includes the installation of new water heaters, more efficient fluorescent lighting, low-flush toilets and upgrades to the system’s automated controls. When fully operational, Beth Israel’s Brooklyn division expects to save approximately $455,000 annually in utility bills.
Another important benefit of the project is the reduction of greenhouse gas emissions equivalent to 150 cars driving 10,000 miles per year. The cogeneration unit will go into operation in March.
