In Operation On Schedule

Siemens turnkey CCPP projects enter commercial operation; installed electrical generating capacity increased by 1.5 GW

Posted on April 25, 2013

Siemens Energy and its consortium partner GS E&C have completed and commissioned two turnkey combined-cycle power plant (CCPP) projects, Sohar 2 and Barka 3, in the Sultanate of Oman on schedule.

Both units went into operation in simple-cycle mode to help meet the country’s strongly growing demand for electric power. Following steam turbine add-ons, both plants commenced commercial operation in combined-cycle configuration in April 2013 – well in time to meet the peak electricity demand during the hot summer months.

For each of these plants, Siemens supplied the main components – two SGT5-4000F gas turbines, one SST5-5000 steam turbine, three SGen5-2000H generators, the electrical equipment and the SPPA-T3000 instrumentation and controls system. GS E&C supplied the heat recovery steam generators and was responsible for other scopes such as the civil construction work, electrical transformers and ancillary systems as well as equipment installation.

With a total electrical generating capacity of 1.5 GW, these two plants increase the Sultanate’s current existing capacity of 4.5 GW to approximately 6 GW. 

Sohar 2 was built in the Sohar industrial park approximately 200 km northwest of the nation’s capital, Muscat, while Barka 3 was erected in the immediate vicinity of Muscat.

The two plants will be operated by Suez-Tractebel Operation and Maintenance Oman LLC (STOMO).
