  1. CSP in Spain Cayetano López CIEMAT Director General December 2011

  2. The elements of change in the energy paradigm The serious drawbacks of the existing energy supply scheme Imply a change whose main vector is: Reduce the carbon content of the primary energy sources Energy saving and efficiency increase Less fossil fuels More renewables More (at least keep) nuclear (Fukushima accident?, Gen IV?) Possible clean use of coal (CO2 capture and sequestration) Fusion (not available in the short term) None of these alternatives are free of problems. To implement them, a big effort in technology development and political support is necessary.

  3. Electricity Generation in Spain, 2010 Biomass & Waste, 3 % Solar, 3 % Coal, 8 % Hydro, 14 % Nuclear, 20 % Wind, 15 % Oil products, 5 % Natural Gas, 32 % Renewables: 35 %

  4. Renewables in the Spain energy supply Renewables in 2010: 11,3% in Primary Energy 13,2 % in Final Energy 35 % in Electricity 5 % biofuels CO2 emissions by unit of electricity produced

  5. The solar resource In good conditions, the daily averaged incoming solar flux is around 220 – 250 W / m2 which, integrated, gives a yearly primary energy of around 2000 – 2200 kWh / m2. This is equivalent to a “rain” of about 20 cm of oil per annum and m2. 1,2 barrel/(year x m2) Solar energy is plentiful but diffuse

  6. CSP prospects in Spain, 2009 With Spain at the Epicenter, Global Concentrated Solar Power Industry to Reach 25 GW by 2020 Cambridge, Massachusetts, 28 April 2009 - Led by development in Spain and potential in the US, concentrated solar power markets are entering a new growth phase, amidst a tumultuous global economic landscape. The CSP industry is scaling rapidly with 1.2 GW under construction as of April 2009 and another 13.9 GW announced globally through 2014, according to a new study from Emerging Energy Research analyzing global CSP markets and strategies. Spain is the epicenter of CSP development with 22 projects for 1,037 MW under construction, all of which are projected to come online by the end of 2010. Despite only 75 MW of CSP under construction, the US continues to offer significant opportunity for CSP, with 8.5 GW in the pipeline and scheduled for installation by 2014. Attracted to promised lower costs, US utilities have turned to CSP -- through both Power Purchase Agreements and direct ownership -- to meet their Renewable Portfolio Standard mandates.

  7. CSP in the world (July 2011)

  8. CSP in Spain (October, 2011) 902 MW, 22 plants 2.600 GWh/y 2.500 MW foreseen at the end of 2013

In operation since June 2004 (ALBAIDA) - CONSOLIDER Project: TRAGUA (Solar Energy for water treatment) - AQUACAT: Egypt, Tunisia, Morocco - VII FP projects: SOLWATERGY (Integration of CSP and Desalination at the Mediterranean Area), Spain, France, Germany, Switzerland, Egypt, Algeria

  22. Renewables 2011-2010 (*) Biomass, Waste. Off-shore, etc Units: GW (GWh)

  23. Over-cost derived from the subsidies to RES

  24. Other financial data RES 2011-2020 Export – Import = 1.400 M€ (2015) to 1.900 M€ (2020) Avoided emissions 2011-2020 = 171 Mt CO2 Jobs related to RES in 2020 = 303.000
