Renewable energy act (EEG)Renewable energy act (EEG)
Federal law (further development of the Power Feed-In Law of 1991)
Priority for feed-in of RE Extensive regulation for grid access legally regulated payment rates
– Long-term perspective and investment security (15–30 years)
– Incentive for the opening up of new potentials and technologies (esp. biomass and geothermal energy)
– Strong incentive for efficiency boost, by degression of payment rates
Cost for consumer
