The tariffs for power from renewable sources are based on reference power plants for each technology and output category. The tariff is applicable for 15-20 years (10 years for biomass infrastructure power plants). In view of technological progress and the increasing degree of market maturity of new technologies, the tariff rates are subject to a regular review. Reductions only apply to new production facilities that are put into operation. IEA/IRENA Global Renewable Energy Policies and Measures Database © OECD/IEA and IRENA, [November 2020]
Amendment: Starting from 2023, there is also the High One-Time Compensation (HEIV) for PV systems without self-consumption. It amounts to up to 60% of the costs of reference systems. For systems with a capacity of 150 kW or higher, the HEIV will be awarded through auctions.
