The $590m contract was awarded by Samsung C&T, which is erecting the facility for Al-Mourjan Project Company, a consortium led by ACWA Power.

Under the contract, the company will supply two SGT6-5000F gas turbines, one SST6-5000 HI-L steam turbine, and three SGen6-1000A-series electrical generators for each of the three units of the power plant.

The contract also include a long-term service agreement for upkeep and maintenance of the gas turbines.

Siemens Energy Sector Gas Turbines and Generators Business Unit CEO Thierry Toupin said the contract is another indicator of the large demand for efficient power generation solutions in Saudi Arabia.

"Our high-efficiency F-class gas turbine is a perfect fit for the Saudi market," Toupin added.

"The Rabigh 2 IPP project expands our already strong market position in this country even further."

Siemens already secured major contract to supply F-class gas turbines for the Qurayyah IPP and Jazan projects in Saudi Arabia, in 2012 and 2013.

Following project completion in mid-2017, Rabigh 2 IPP will have an installed electrical generating capacity of 2,060MW to supply Makkah Province with electric power.
