4 Q: own calcula+ons based on APG, 2015;

5 + Photovoltaic? Note: Ø2015 x10 = 4600 MW Q: own calcula+ons based on APG, 2015;

6 + Photovoltaic? Note: Ø2015 x10 = 4600 MW Q: own calcula+ons based on APG, 2015;

8 +Wind power? Note: Ø2015 x5 = 10,900 MW Q: own calcula+ons based on APG, 2015;

9 +Wind power? Note: Ø2015 x5 = 10,900 MW Q: own calcula+ons based on APG, 2015;

10 +Wind power and Photovoltaic? Wind: Ø2015 x5 = 10,900 MW PV: Ø2015 x10 = 4600 MW Q: own calcula+ons based on APG, 2015;

11 +Wind power and Photovoltaic? Whats the price for? Wind: Ø2015 x5 = 10,900 MW PV: Ø2015 x10 = 4600 MW Q: own calcula+ons based on APG, 2015;

13 Assumptions Photovoltaic Investment 1300 kw p -1 investment incen+ve 200 kw p -1, 1 year in delay 13 years, 20% equity (8%)/ 80% dept (3%) Opera+ng costs Insurance: 2,50 kw p -1 a -1 Cleaning: 6,50 kw p -1 a -1 ==> Total Costs: 120 MWh -1 Q: BGBl.

14 What s the price for? Shadow price approach Restriction: land constrained economy [ MWh el -1 ]

15 Flexible electricity generation Pumped storage power 113, ~7980 MW, 13,743 GWh 2015 /14,990 GWh 2014 Babery storage network level 7? Smart Grids? Small hydropower Biomass cogenera+on plant Biogas plants Wind turbines

16 Flexibility of biogas plants -50%

17 +50% -50%

18 Flexibility of biogas plants +25% -25%

19 Flexibility by wind turbines Full load hours Full-load-hours

20 Conclusio We will need all capacities we can get + 50% to meet the fossil share and the current import requirement + 30% (??) for electromobility +??% for electric heating systems +??% for changes at industrial processes We cannot allow ourselves wasting energy Wind power and Photovoltaic needs to be stored Counterbalancing the region is becoming increasingly important A good mix between the renewables help lowering energy costs the key criterions are not the specific generation costs the key criterion is the supply security (at any time)
