Siemens Energy will build two turnkey combined cycle power plants in Oman for OR654m ($1.7bn).
The two 750MW plants, Barka III and Sohar II, will be built by the firm along with its South Korean partner GS E&C for a GDF Suez-led consortium.
In May 2012, both units will enter into service in simple-cycle mode and will be extended to combined cycle by April 2013.
Siemens will also supply two SGT5-4000F gas turbines, one SST5-5000 steam turbine, three SGen5-2000H generators, electrical equipment and SPPA-T3000 instrumentation and control system.
The project also includes a long-term service agreement for the gas turbines.
GS E&C will supply the heat-recovery steam generators and be responsible for civil works, transformers and ancillary systems and equipment installation.
Oman Power and Water Purchasing awarded the projects to lead developer GDF Suez and its co-developers Multitech, Sojitz Corporation, Shikoku Electric Power, and Public Authority for Social Insurance.
