The Deersum project uses both wind and biogas to provide energy for a rural community in a windy area of the Northern Netherlands. It uses a 160kW wind turbine in combination with a 210m3 collective manure digestion plant for electricity generation. After a year, the polyester blades of the turbine developed hairline cracks and required modification and reinforcement. The digestion plant suffered problems relating to the manure pumps, desulphurisation of the gas, low conversion efficiency and occasional formation of scum. The aggregate electricity output amounted to 255,000 kWh per year, 69% of which could be utilised in Deersum, at an average cost price of Dfl 0.33 per kWh. This price could be reduced by various means to Dfl 0.12 per kWh. This does not take into account benefits to the environment or by way of employment opportunities.
