Blending into EU energy policy for 2020-2030 • EU-ETS, EU-RES-E-targets and support scheme • Leveraging intra-EU synergies in CO2 -mitigation • Cross-border „Bidding Zones“, incl. capacity mechanism design (if/how) ? 2. Drastically rethinking RES-E-Support (EEG) • RES E-targets „out of the money“ – but still not fundamentally revised • Reducing and refinancing difference cost (excess cost of RES-E-support) • Integrating RES-E into the European electricity market ( ) ? 3. Improving generation adequacy where needed • No nationwide need for action • Regional situation partially critical, esp. in Southern Germany ? 4. Reducing state-induced price distortions • Avoiding economic inefficiency • Avoiding further redistributional effects (?) Thank you very much for your attention.
