2 slide 2 decentralized renewable energies (RE) and storages Examination area - BW large power plants of dispatchable renewable energies feeding point into the AC grid ~ 100 % RE import of dispatchable renewable energy HVDC point-to-point HVDC point-to-point balancing authority area distribution network AC 10.8 mio. inhabitants, 80 TWh/y - in the year 2012 import of dispatchable renewable energy transmission network AC Source: ( W%C3%BCrttemberg) Source: Hess, D., 2013, Fernübertragung regelbarer Solarenergie

6 slide 6 System problems in Baden-Württemberg in the year 2050 with 95% renewable energy (RE) in electricity supply installed capacity: 55 GW installed capacity: 35 GW dependence of gas production surpluses Quo vadis? with dispatchable energy on demand -> ideal power mix % RE Two scenarios for the year 2050, each with 95% renewable energies for the electricity supply in Baden-Württemberg Today, the decision must be made specifically for the choice of one way!

8 slide 8 Exclusion areas Morocco! The sites are just scientific! Economic possible sites 1 2 settlements protected areas water agriculture and forest slope (>2%) dunes no exclusion exclusion [kwh/m²y] The economic CSP potenital in the northern part of Morocco is at about 8450 TWh/y with km² CSP gross land demand -> one site with 150 km² needs only 0.8% of this potential Source: Hess, D., Fichter, T., 2013, Fernübertragung regelbarer Solarenergie

9 slide 9 First design of the CSP-HVDC site, cost and land requirements MOR-E-F-D HVDC 2600 km 1.7 GW / 1.5 GW net 3 billion 150 km² CSP 2.2 GW CSP billion 150 km² MOR-E-F-D HVDC 2300 km 1.7 GW / 1.5 GW net billion 75km² O&M: 4-5 Cent/kWh LCOE: Cent/kWh Daxlanden (Dax) Eichstetten (Eic) CSP 2.2 GW CSP billion 150 km² -> 9.32 TWh/a billion (real 2010) feasible until 2024 Missour (Mis) Marrakesh (Mar) EEZ sea borders Source: Hess, D., 2013, Fernübertragung regelbarer Solarenergie
