The German Renewable Energy Sources Act (EEG) first became effective on 1 April 2000
and covers the purchase and compensation of electric power generated exclusively
fromrenewable sources of energyby service companies who operate grids for general
Biogas plantsgenerating power from biomass as well
as wind turbine generator systems are covered by
the Renewable Energy Sources Act (EEG).
According to this, the local energy supplier is obliged
to purchase the generated power at a fixed price and
to feed it into the grid.
The German legislator has enacted in the German biomass regulation (Biomasse VO)
the bioenergy sources (used for the production of electric power) that are authorized
to be compensated as well as the methods of energy conversion.
On 30 June 2011, the 2012 amendment of the Renewable Energy Sources Act was
passed in the second and third reading in the plenary session of the Bundestag.
The new version is effective from 1 January 2012.
There is a lot of new content in the EEG 2012, mainly relating to new plants that
are taken into operation after 1 January2012. However, even for existinginstalla-
tions or their extension the EEG is quite important.

There are better conditions for smaller biogas plants, especially those up to 75 kW
waste materials. They will now receive 25 ct/kWh (§ 27b).
Bigger plants beyond 500 kW will receive only 6 instead of 8 ct/kWh for the fermentation
of liquid manure. The aim is to make on-farm plants more attractive and avoid long
up to 75 kW, it amounts to 25 ct/kWh
up to 500 kW, it amounts to 6 ct/kWh
up to 750 kW, it amounts to 5 ct/kWh
up to 5 MW, it amounts to 4 ct/kWh
Biogas plants beyond 5 MW do not receive any resource bonus.
The maximum proportion of maize shall be only 60% of the composition for all new biogas plants.
This promotes the usage of waste materialssuch as manure, landscape preservation materials
or clover and alfalfa.
Waste materials receive 8 ct/kWh for up to 5 MW (liquit manure beyond 500 kW receive only 6 ct).
The fermentation of waste materials will be compensated according to their proportion in the input
material. In this way, there is an incentive for all new plants to use waste materials from the
New biogas plants, with the exception of small manure-based installations, and systems for
processing biogas must prove in the future that at least 60% of the heat will be used sensibly.
However, for new plants there shall be a grace period for the first two years of operation,
during which only a 25% heat recovery must be proven.
Biogas systems that feed the electricity into the grid as required will receive a bonus to
sate for the fluctuations in wind and solar energy. This will also apply to existing plants.
The fermentation of organic waste will receive more support in the future. Existing systems can
also take advantage of this regulation (§ 27a). In this way, the German parliament aims to give
more support to the separate use of organic waste.
