Biogas stations are mainly constructed in waste water treatment plants, communal landfill sites,
industry and agricultural concerns concentrating on livestock rearing.
Since biogas usually arises as a
side product of the treating of organic waste, the operation of cogeneration units on this fuel is
economically very advantageous.
New energy legislation guarantees the operator of cogeneration
technology using renewable energy resources a long-term stable purchase price for electricity at a
very interesting rate.
If there is natural gas distribution available in the biogas station, it is possible to use a dual-fuel
cogeneration unit for combined running on both natural gas and biogas (fuel switching).
This is
most advantageous in cases where the production of biogas is not uniform.
