The CHP system (pictured) produces enough power to supply 84 percent of the 2-million-square-foot Stratford facility’s needs – equal to the annual energy use of approximately 1,100 area homes. The new system also will provide 85 percent of the facility’s steam heating needs, Sikorsky says.
Sikorsky’s CHP project started three and a half years ago with a $26 million capital investment by the company and a $4.66 million cogeneration incentive grant from the State of Connecticut.
Carrier and its Noresco business, which, like Sikorsky, are owned by United Technologies, provided design and construction consultation on the project.
In 2010, Sikorsky installed 450 solar panels on the rooftop of the Stratford campus’s engineering building. The array currently generates 106,250 kwh of energy annually.
In other CHP news, Sustainable Environmental Technologies has shipped the first order for its MultiGen combined cooling, heating and power, plus water generation systems to an unnamed commercial facility in Australia for a retrofit construction project.
The MultiGen is able to achieve up to 95 percent overall efficiency, SET says.
And finally, a recent study by the EPA’s voluntary Combined Heat and Power Partnership, has found potential for more CHP system installations at U.S. wastewater plants.
“Opportunities for Combined Heat and Power at Wastewater Treatment Facilities: Market Analysis and Lessons from the Field” says that CHP systems are currently installed at 101 wastewater treatment facilities in the U.S. but that such systems would be technically feasible at a further 1,351 plants.
