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]
