New York’s Largest On-Farm Biogas Power Project Generates Renewable Energy for Nearly 1,000 Homes

Dairy digester mixes manure with waste from local food processors to produce power.


U.S. Sen. Charles Schumer (D-N.Y.) joined state and local officials today at the grand opening of New York state’s largest on-farm, “co-digestion” biogas power project, marking an important boost to the state’s renewable energy production and sustainability efforts.

The facility is located at Synergy Dairy, a 2,000-head dairy farm in Covington, Wyoming County, southwest of Rochester, N.Y.
 
CH4 Biogas LLC built, owns and operates the project under the name Synergy Biogas LLC. The Synergy Biogas LLC plant also is the state’s first biogas project specifically designed for the co-digestion, or processing, of animal and food wastes. The biogas created in the 120,000-gallon co-digester is fueling a GE ecomagination-qualified, Jenbacher J420 biogas engine to generate 1.4 megawatts (MW) of renewable electricity.
 
By anaerobically digesting waste from local food processors in addition to the dairy’s cow manure, the 425 ton per day, mixed-waste facility is more cost-effective. The facility has created about a half dozen jobs while enhancing the efficiency of the 30-employee farm’s operations and sustaining area food manufacturers and haulers.
 
The New York State Energy Research and Development Authority (NYSERDA) is providing $1 million in incentives for the facility.
 
“This Synergy co-digestion biogas project is the cutting edge of energy technology and is an absolute revenue-producing game changer for our dairies and local economies,” said Senator Schumer, whose office helped coordinate federal and local funding for the project. “By recycling agricultural waste in biogas plants, dairies can reduces disposal costs, produce affordable renewable energy to run their operations and gain a revenue source by selling excess power to the grid. I’ve been proud to help keep this project on track to ensure it crossed the finish line.”
 
Schumer’s office also worked with the Wyoming County Industrial Development Agency to help Synergy Biogas LLC complete the facility and partner with Cornell University and Rochester Institute of Technology to evaluate the project’s performance.
 
The project is expected to reduce the dairy farm’s base load greenhouse gas emissions by about 8,500 tons of CO2 annually, which is equivalent to the CO2 emissions of 1,700 automobiles. The facility also will produce an estimated 17,500 cubic yards of bedding material for livestock while reducing manure odors and helping the farm manage nutrients applied to cropland.
 
Through its partnerships with local food manufacturers, Synergy Biogas LLC already has diverted more than 1.14 million gallons of food waste from landfills and wastewater treatment facilities, highlighting another environmental benefit of the project.
 
“We are excited to launch our new co-digestion biogas project that will optimize the recycling of agricultural biomass waste into a valuable renewable energy resource to help reduce our operational costs,” said John Noble, president and CEO of Synergy Dairy.
 
National Grid is supporting the project as part of its broader strategy to help upgrade New York state’s energy infrastructure, promote further economic growth in the region and encourage the development of renewable energy resources. Under its renewable energy marketing program, the utility is purchasing the electricity generated by the biogas plant, which it states will produce approximately 10,000 megawatt-hours of renewable energy per year—enough electricity to power nearly 1,000 homes. National Grid provided a $750,000 grant through the company’s Renewable Energy and Economic Development Program to cover the cost of building the substation that connects the facility to the grid.
 
Northeast Energy Systems, a U.S. distributor of GE’s Jenbacher engines, supplied the engine to CH4 Biogas.
