Jordan Dairy Farms in Rutland, Massachusetts, founded in 1885, has been operated by the Jordan family for six generations. The farm is a member of Dairy Farmers of America (DFA). Operated by brothers Randy and Brian Jordan, the farm has survived despite an extraordinary decline in dairy farm numbers across Massachusetts.

Prior to becoming a part of the Vanguard Renewables partnership, Jordan Dairy Farm’s monthly electric cost alone was more than $2,400. Partnering with Vanguard on the Farm Powered anaerobic digester project, the farm now receives low-cost energy, hot water, and heat for reuse.

Nearly 22,000 tons of food waste and beverage waste is collected annually from food processors and users is combined with more than 9,000 tons of manure a year from the farm in a 500,000-gallon digestion tank. Manure and food waste are mixed and microorganisms convert sugars, fats, and other compounds into biogas annually producing more than 4,200 MWh of renewable energy and odor-free, low-carbon, liquid fertilizer to enhance soil health and increase crop yields. The anaerobic digester has revolutionized how the farm gets power, while fitting seamlessly into this quintessential New England dairy farm.
