Zusammenfassung

The Climate Policy Initiative finds that while sufficient capital exists to meet Germany's renewable energy expansion goals, the specific mix of investors and the design of regulations are critical for cost-efficiency. Key regulatory areas include auction design, support mechanisms, and long-term targets. The report highlights that instability or poor design—such as delays in auction rounds or shorter support periods—can significantly increase bid prices and overall costs. It also emphasizes the need for energy market flexibility to avoid negative electricity prices and investor risk.

• Sufficient capital is available to meet the German government's expansion targets, provided there is an appropriate political framework, though the specific mix of investors is essential for cost-effectiveness.
• Inefficiencies in auction design and support mechanisms directly increase costs: a 12-month delay between auction rounds can raise bid prices by 21%, and reducing the support period from 20 to 15 years could increase bid prices by 15-18% depending on the technology.
• Inflation-indexed support could lower bid prices by 18-20% and attract institutional investors.
• End-consumers are a significant source of equity; they provided over 25% of equity investments in 2015 and are projected to provide 50% of the equity investment potential by 2020.
• Current energy market designs are not suited for a system dominated by renewable electricity, potentially leading to over 1,000 hours of negative electricity prices by 2030. Without flexibility mechanisms, current rules for reducing support during negative prices could increase bid prices for onshore wind plants by 17% by 2020.
• Long-term expansion targets reduce costs through process optimization; for example, between 2006 and 2014, non-module costs for ground-mounted photovoltaic systems fell by 11.5% per year and rooftop installations by 7.7% per year.
