Siemens will supply components worth over $1bn for a combined cycle power plant to a Saudi Arabian-consortium.

The consortium comprises Al Arrab Contracting Company, Saudi Arabia, and the Chinese SepcoIII Electric Power Construction.

The 2,400MW Ras Az Zawr power plant to be constructed 75km north-west of Jubail, is expected to begin operations in early 2014.

Under the contract, Siemens will supply 12 SGT6-5000F gas turbines, five SST6-4000 steam turbines, 17 SGen6-1000A generators, ten heat-recovery steam generators, associated electrical equipment and SPPA-T3000 I&C.

The facility, with an associated seawater desalination facility, will supply electricity to an aluminium smelting plant, and about 225 million gallons per day of drinking water to Riyadh.
