The opening has taken place 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.
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 (NYSE: 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. 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,” said Senator Schumer, whose office helped coordinate federal and local funding for the project.
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 baseload 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 odours 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.
The Synergy Biogas LLC operation is the first of several N.Y. dairy farm digester projects that CH4 Biogas and GE Energy plan to build. Such projects illustrate how the state’s food and beverage industries can utilize their on-site waste streams to produce free fuel for power generation.
According to the New York State Department of Agriculture and Markets, in 2011 the state had 5,300 dairy farms with more than 600,000 dairy cows. However, less than 20,000 of those cows were being utilised in energy production, through the use of 17 digesters that produce a combined 3 MW. As of 2011, an additional 17 digester systems were awaiting installation to generate a combined 6 MW.
The Synergy project illustrates how incentives offered by NYSERDA are supporting the purchase, installation and operation of more anaerobic digester gas-to-energy systems to help the state create a more sustainable agricultural sector.
In addition to NYSERDA and National Grid‘s respective financial support, the Synergy Biogas LLC project also qualified for a 30 percent investment tax credit (ITC) under the federal Energy Policy Act of 2005. As part of the 2009 federal stimulus initiative, the U.S. Treasury will pay this tax credit as an ITC cash grant for qualifying projects that began construction before the end of 2011.
