Project Description:

The biogas plant in Kamenice was put into operation in 2010. It processes approximately 35 000 tons of animal by-products derived from primary agricultural production and 13 000 tons per year of energy crops. Hourly production of biogas, which is produced in two primary digesters with a capacity of 2 700 cubic meters and one secondary digester a volume of 3 400 cubic meters is 400 to 500 cubic meters. The produced biogas is burned in two cogeneration units with a total output of 990 kWel. 

Produced electric power is supplied to the distribution system and heat in addition to heating the fermentation tanks delivered to the customer for the purpose of drying wood. Own electricity energy consumption of the biogas plant is around 8%, depending on the produced output.
