Fepro Farm in Cobden, was the first biogas farm in Ontario and has been operating for six years. It is a dairy farm run by Paul and Fritz Klaesi and sons, with 300 head of cattle, including 142 milking cows. The farm also has 350 acres of corn, 70 acres of small grain and 210 acres of alfalfa. The farm originally had a small digester coupled to a 50kW generator, but has since expanded to a 2,500m3 digester and 500kW generator. The digester is fed with a mixture of manure and off-farm wastes. Apart from generating electricity for sale to the grid, the heat from the engine is used to heat the farmhouses and a corn dryer.
