History

1999 Discussion on ISCC technology, World Bank to sponsor four ISCC projects (Egypt, Morocco, India and Mexico) by grant of 50 Million USD each.

2001 FichtnerSolar awarded the Planning and Engineering (Technical Design Report, Specifications)

2004 Planning modified and decided tender in two lots (Solar Island and Combined Cycle Island).

2007 Bidding, Negotiations and Contract Awards: • Orascom with Flagsol for Solar Island• Iberdrola with Mitsui for Combined Cycle Island• FichtnerSolar for Project Construction Management

2008 February: Start of Construction

Design: Solar Island

• Solar Collectors– 160 SKAL‐ET 150 based parabolic trough collectors, reinforced

or regular depending on position in solar field.

• HTF System– 40 loops, thereof each 9 West and East of the Power Block and

22 in the South

– 3x50% HTF main pumps, 2x50% freeze protection pumps

• HTF Area Concrete Building– HTF System Control Equipment, Electrical Systems Solar Island

• Workshop and Warehouse

5

Design: Combined Cycle Island• Gas Turbine

– General Electric Type MS 6111 FA , 74 MW at 20°C ambient temperature

• Steam Turbine– Siemens SST 900, 60 MW at 50 MJ/s Solar Heat Input, 36 MW

without Solar Heat Input

• Heat Recovery Steam Generator and Solar Heat Exchangers– Steam generated by Solar Heat Exchangers (Pre‐heater +

Evaporator) and fed into high pressure steam drum

• Cooling Towers

– Evaporative cooling with make‐up water from Nile

6

Site and Plant Arrangement

• 87 km South of Cairo

• 3 km East of Nile

• 4 Collector Areas

• Power Block in the North

• Non‐Plant Area and

Access Road in West

• Balance of Plant in North

• Gas Pipeline and Gridline passing in the North

• In the South cultivated Land, in the West small Wadi

Absorber Tube Schott PTR 70

• Improved reliability • Improved match between glass and metal

coefficients of thermal expansion • 100% testing of glass-to-metal seal • Improved performance • New bellows configuration that compresses

when tube is hot • Improved getter mounting to keep getters cool to

increase hydrogen absorption capacity • More durable anti-reflective coating on glass • Reduced hydrogen permeation • Selective coating

10

Sun tracking of the Solar Collectors by a sensor

• Photovoltaic cell causing two currents

Wind breakers

Task: Reduce wind loads on the collectors
