6 Various CSP applications exist in the MENA region Growing population results in a surging energy demand Collectors Solar thermal steam generation Power generation Absorption cooling Seawater desalination Enhanced Oil Recovery Applications Electricity consumption Air conditioning needs Freshwater shortage Petrochemical industry 150 GW of installed capacity for electricity generation in MENA Forecasted annual growth of more than 7% (~10 GW) In major population centers in the Middle East, up to 80% of electrical power is employed for air conditioning and refrigeration Annual demand of 155 billion m³ Over-exploitation of groundwater resources beyond the point of natural replenishment Conventional methods leave two thirds of the oil underground Revival of mature or abandoned fields through steam injection June

7 MENA s physical attributes are almost unparalleled Regulatory changes to kick-start CSP after Spain s success story Spain Middle East and North Africa Transfer of know-how 50 MW Andasol 3 with 7.5 h storage 2,000 2,200 kwh / m²a Limited availability of land Availability of water allows for wet cooling Feed-in tariff (FiT) Several projects completed, 60 projects pre-registered for FiT Typical project DNI Land resource Water resource Support scheme Market maturity Kuraymat 140 MW ISCC (20 MW solar) 2,000 2,700 kwh / m²a Plenty of uninhabited land and flat topography but challenging soil conditions Higher cost for dry cooling due to lack of water Tenders First projects under construction, ambitious CSP expansion plans (e.g. DII) Participation in / EPC execution of pre-registered projects Market development aiming to exploit first mover advantage June

8 The investment landscape for CSP is still evolving MENA characterized by privatization and administrative barriers Strong state involvement in the energy industry but ongoing privatization of government-owned utilities (e.g. Abu Dhabi, Oman) MENA energy market Interconnection of the GCC electricity grid system planned to allow for electricity trading and capacity balancing Rising (peak) electricity demand mainly due to air conditioning systems and growing population Especially energy importers such as Jordan and Morocco seek to obtain energy security Administrative barriers and no clear ownership at government level of issues related to renewable energy Trend to divert vast oil and natural gas resources as feedstock into high-margin downstream petrochemicals; thus solar energy becomes attractive to replace fossil fuels for electricity generation GCC = Gulf Cooperation Council June

9 MENA countries are building a sound project pipeline Governmental plans are key in ME, IFC and MSP are drivers in NA Algeria Morocco Tunisia Egypt Jordan Qatar UAE Oman North Africa Middle East Morocco Ouarzazate (500MW) and MSP Ain Beni Mahar ISCC (20 MW solar) Algeria Tunisia Egypt Feed-in law since 2004 and MSP Hassi R Mel ISCC (25 MW solar) 40 solar power projects planned for 2010 with MSP and IFC Kuraymat ISCC (20 MW solar) Jordan Ma an (100MW), FiT expected Qatar Solar plan for up to 3500MW by 2020 UAE Shams I signed, Shams II expected Oman Feasibility Study in progress Maturity of CSP market IFC: International Finance Corporation, member of World Bank Group MSP: Mediterranean Solar Plan June

16 Parabolic Trough Today s only large-scale commercial technology with storage Receiver Glass mirrors Steel Structure One-Axial Tracking Solar Collector A steel support structure holds 4 mm curved glass mirrors in a parabolic shape In the focal line of the parabola, receiver tubes absorb the concentrated energy and turn it into heat The tubes are streamed by a thermal oil that conveys the energy to a heat exchanger or steam generator Solar Field 1,300 m Power Block 1,500m Andasol 3 Setup: 4 collectors per loop Length of a collector: 150 m Distance between rows: 17 m Collector surface area: ~500,000 m² Number of loops: full load hours of storage Power Plant Setup solar field with the heat transfer fluid storage system, 2 tanks, 27,000 tons molten salt steam turbine, generator, and cooling circuit Alternatively, the solar field can be integrated into a gas combined cycle or combined with an existing coal power plant Funktion eines Parabolrinnen-Kraftwerks.exe June

17 Solar Tower Highly efficient and scalable technology of the future Solar Tower with Receiver The receiver is mounted on top of a standard wind turbine shaft The receiver has one north and one south facing absorber, each gathering 170 of insolation Water is directly evaporated and superheated to approx. 440 C without heat exchangers Mirror Field Instead of individual foundations, a steel structure is employed The structure holds thousands of only 1.2-2m 2 mirrors Each mirror can individually be controlled to focus onto the absorber Mirror control software is esolar s core competency Power Plant Setup The solar field is largely pre-assembled and can be installed quickly with little labor and machines A modular plant design combines high standardization with adaptability The steam of the modules is merged into power blocks of up to 50MW June

18 Linear Fresnel Robust mid-size technology with great cost potential Solar Collector Module A steel structure holds rows of nearly flat mirror segments, 9m above them is the receiver unit Each segment is 6m long and 60cm wide. One module is 96mx21m and made up of 24x16 mirror segments One row is controlled by one motor that pivots the 16 mirrors every few seconds by fractions of a degree Solar Field The modules are run on direct steam The field is split-up into three divisions: heat water, evaporate water to saturated steam, superheat steam Steam temperatures of 450 C can be achieved Multiple modules are interconnected according to the irradiation and output Plant Setup and Operations As the collector produces steam, this is directly fed into a turbine or used as process heat Solar Thermal Steam Injection Conventional Production The process steam can be used for desalination, enhanced oil recovery, a.o. Intermittent coverage can be compensated through de-/focusing mirrors or integration of co-firing Steam Heated Reservoir Oil Production Well June
