What is the future of quantitative finance

Future financing of renewable energy systems in Germany Study on behalf of the Federal Ministry for Economic Affairs and Energy

In the project “Future Financing of Renewable Energy Systems in Germany”, Fraunhofer ISI, Consentec, ZSW, Navigant, Vienna University of Technology and the Environmental Energy Law Foundation examined alternative models for future financing of renewable energies in the electricity sector.

In the report "Future scenarios for renewable energies - how much and what funding will be needed in the future?", The future financing requirements for renewable energies in the electricity sector are analyzed and alternative funding instruments are discussed for various scenarios. On the one hand, there is the question of the extent to which further funding for renewable energies in the electricity sector is necessary in the future. On the other hand, it is investigated how such funding can be meaningfully structured under different framework conditions. To answer both questions, the paper contains both quantitative-model-based and qualitative analyzes.

In the report "Effects of climate and energy policy instruments with a focus on the EEG surcharge, electricity tax and CO2 price", the income and refinancing side is analyzed, that is, the funding of the subsidy, which is currently provided through the EEG surcharge. In essence, the effects of refinancing the EEG surcharge and CO2 pricing with regard to sector coupling and distribution effects were examined here.

In addition, the report “Future financing of PV systems below 750 kW - demand, requirements, costs, scenarios and funding” discusses possibilities for funding small-scale PV systems that are not covered by the current tenders under the EEG.
