Microturbine Generates Electricity and Heat at New York Grocery Store
A New York supermarket recently became the first grocery store in the country to install a 60kW microturbine. Waldbaum's, a Hauppauge, N.Y., supermarket, installed a natural gas-fueled microturbine that generates 15% to 20% of the store's electricity and serves as a dehumidifier. The $180,000 project was funded in part by the U.S. Department of Energy, the American Gas Association, the Gas Technology Institute, KeySpan, and the New York State Energy Research Development Agency. Because energy is the third highest expense for a supermarket, Waldbaum's is also considering installing seven to 10 turbines at another site in Centereach, N.Y. For more information on microturbines, read "Pint Sized Power Producers," (
OOOPs, looks like someone already beat me to the Capstone info, sorry. BTW, if you happen to be in Panama City, Florida, visit the Navy base there and ask if you can tour a Hovercraft. They have two onboard 60KW microturbines made by TurboMach
