Kommunalkredit
Federal grants and incentives for renewable energy producers such as firms, associations and public entities are administered primarily by the Kommunalkredit. These federal grants typically constitute 30% of eligible costs and are granted to entrepreneurs investing in small hydro plants, modern biomass-based heating systems which include small networks for district heating, biogas, sewage gas, geothermal systems, heat pumps, solar thermal above 10 m2, photovoltaic and wind installations. These grants can also be combined with financial support from the Länder to cover 66% of costs.
