Background – Important Dates

the conditions for practical Completion and the Practical Completion Certificate (PCC) was signed.

2016 was the third commercial operational year for the plant.

Climate Challenges

Climate Challenges … continued

High Dust Concentration • Dust results in relatively low DNI. • Dust increases the mirror soiling

rate, decreasing the average reflectivity of the mirrors quicker than in other locations

High Wind Speeds • The vast Rub’ Al Khali desert is a

major source of wind. • Summer months are the windiest

carrying a lot of dust and causing many disturbances in operation

High Temperature • Efficiency of the water/steam

cycle. • Steam condenser design. • Higher parasitic consumption.

Water Scarcity • The main source of water is

desalination, which means high cost of water.

• No rivers, lakes near the plant affecting condenser design.

Main Operation Modes • Normal operation Solar + Fuel

• Solar only operation • Fuel only operation Firm output mode as requested by PPA
