The German Renewable Energy Sources Act (EEG)

The development of renewable energies in Germany is a true success story. The figures speak for themselves – the target was for renewable energies to cover 12.5% of electricity needs by 2020. This goal had already been significantly exceeded in 2007, with a figure of 14.2%. And growth continues to be rapid – in 2014 renewable energies met 27.4% of electricity needs.

The foundation of this success is the innovative “Act for the Precedence of Renewable Energies” – known as the Renewable Energy Sources Act (EEG) – which first came into force in 2000. The act promotes the further development of technologies for the production of electricity from renewable sources. It has been so successful that it has been adopted in over countries.

Key features of the EEG:

Connection and purchase duty

Electricity grid operators are, for example, obliged to feed power generated by wind turbines and photovoltaic systems into the public grid. For every kilowatt hour (kWh) of electricity generated the system operator receives remuneration which is guaranteed for a continuous period of at least 20 years. The Act explicitly specifies the feed-in tariff rate for each individual technology.

Compulsory registration

All new systems must be registered with the Federal Network Agency, including information on the location and performance, in a centralized register. The advantage for system operators is that they have greater legal security vis-à-vis network operators.

Feed-in management

Energy providers are allowed to temporarily disconnect systems from the grid, should it be overloaded. Remuneration for the power produced is paid independent of this. There are thus no disadvantages for the system operator and grid stability is increased.
