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
