Tecogen to install CHP system at N.Y. wastewater plant

By Anna Austin | April 23, 2012

Tecogen Inc. is installing a combined-heat-and-power system at the Medina, N.Y., wastewater treatment plant.  

The 60 kilowatt (kW) system will utilize biogas generated from waste sludge treatment in anaerobic digesters, and the resulting electricity will be fed into the power grid. The project is expected to offset the large amount of electricity currently consumed by the plant, according to Tecogen. The company projects natural gas and electricity cost reductions to initially exceed $10,000 per year.

Ram Shrivastava, CEO of plant upgrade designer Larsen Engineers, said the plant currently produces enough biogas to generate about 40 kW of electricity, though more biogas may be produced in the future.  

The site has been awarded a Green Infrastructure Grant from the New York State Environmental Facilities Corp., with awards recipients with grants of up to 90 percent of their construction costs, including eligible planning and design costs. All recipients are responsible for providing a minimum match of 10 percent from local or state funds.
