10 German targets for electricity gross consumption 80% renewable -10% (compared to 2008) -25% (compared to 2008) 65% 50% 35% Energy Concept of the German Government, Autumn 2010

11 Agenda German electricity mix Political Targets Price Formation at the Whole Sale Market Historic Prices and Explanation patterns Surcharge for RES Special analysis for future solar costs 11

12 Consumer price for electricity Germany Source: Federal Network Agency, own figure

13 Merit order of power plants price

14 14 Merit order – without nuclear price

15 15 Merit order – with more RES price

23 Consumer price for electricity Germany Source: Federal Network Agency, own figure

24 24 Renewable Energies Act: guaranteed and priorised feed-in guaranteed payment Feed-in tariff for RES §

25 25 € MWh demand supply curve of conventional power plants electricity price RES-electricity production guaranteed feed-in tariff proceeds for TSOs of RES-sale differential costs are reallocated to all consumers = RES surcharge RES-costs and whole sale market

26 26 RES-surcharge: difference Contributions of the most important factors influencing the increase of the German EEG surcharge in 2013 (5,3 ct / kWh) compared to 2012 (3,6 ct / kWh) 1.68 ct/kWh overall Source: Calculations by Oeko-Institut

27 Agenda German electricity mix Political Targets Costs and Price Formation at the Whole Sale Market Surcharge for RES Special analysis for future solar costs 27

28 Decrease of future feed-in tariff for photovoltaics 28 Source: EEG, Calculations by Oeko-Institut

29 29 Future solar electricity production … in the years 2012 bis 2016 ordered by construction years of plants Source: Calculations by Oeko-Institut

30 30 Future costs for solar electricity … in the years 2012 bis 2016 ordered by construction years of plants Source: Calculations by Oeko-Institut

31 31 Future share of RES surcharge for solar electricity … in the years 2012 bis 2016 ordered by construction years of plants Source: Calculations by Oeko-Institut

32 Future price development for consumers? 32 liberalised market more RES „energy only markets“ will not be enough Source: Federal Network Agency, own figure capacity payments?
