Renewable.Energies.Heat.Act.(EEWärmeG)..
next to the new EEG, the renewable Energies Heat act (EE-
WärmeG) also became effective on january 1, 2009. according
to this law, 14 percent of the German heat demand (final energy)
is to be produced from renewable energy sources.
Crucial elements of the law are:
obligatory utilisation
Financial promotion
specific promotion of heating networks
Buildings erected after january 1, 2009 are obliged to employ
renewable energies for their heat supply. This obligation applies
to all owners (private, state, economy). Exempted are buildings
for which a building application or building listing has been issued
before january 1, 2009. all forms of renewable energies can
be used, also in combinations. When using biogas, the obligation
is generally met if 30 percent of the heat energy demand of
the respective house is covered by it. The biogas is to be used in a
cogeneration plant in this context. In the case of the utilisation
of gas taken from the gas grid, special requirements are binding
regarding the conditioning and feeding-in. Methane emissions
and power consumption must be abated “according to the
best available technology”. In case of methane emissions this is
usually accepted if the gas quality requirements of the Gas Grid
Entry regulation (GasnZv) according to § 41f are met. The process
heat needed for conditioning and feed-in must furthermore
be produced from lost heat or renewable energy sources.

Gas.Network.Access.Ordinance.(GasNZV).
1. Preferred Network Access.
according to § 41c of the Gas network access ordinance (German:
Gasnetzzugangsverordnung, GasnZv), grid operators on
all pressure levels are obliged to grant preferred grid access to
plants which have put in a request. The grid access costs are split
equally between the grid operator and the biomethane supplier.
according to §41b GasnZv, the grid access consists of the
connecting pipeline (up to 10 km), the gas pressure metering
plant, the compressor and the calibrated measurement plant.
The grid operator is the owner of the grid access and covers the
costs of maintenance and operation.
2. Preferred Network Entry.
according to § 41d, 1 GasnZv, grid operators are to grant preference
to biomethane transport clients when it comes to concluding
entry and exit contracts, as long as these gases are compatible
with the grid.
The feed-in of biogas cannot, according to § 41d, 2 GasnZv, be
denied by the grid operator under the premise of an existing
capacity shortage. at the same time, the grid operator is obliged
to take all necessary and economically sensible measures to
ensure and optimise the admittance capacity.
3. Extended Accounting Balance.
For biogas transport clients, the GasnZv provides special regulations
varying from part 7 in § 41e GasnZv on the extended
accounting balance in biogas accounting. Especially in the
summer months, there is usually a distinct difference between
the biogas fed in and the biogas discharged. In order to balance
the account, the transport client is categorised into an account-
