Siemens Energy has received an order to supply six gas turbines, three steam turbines and nine generators for a Saudi power plant in a deal worth $590 million.
The order relates to the Rabigh 2 IPP combined-cycle power plant in Saudi Arabia, the company said in a statement.
Korean construction company Samsung C&T is building the facility for Al-Mourjan Project Company, a consortium under the direction of the independent power producer ACWA Power.
Following project completion in mid-2017, Rabigh 2 IPP will have an installed electrical generating capacity of 2,060 megawatt to supply Makkah Province with electric power.
The Siemens contract includes commissioning support services, and a long-term maintenance service agreement, the statement added.
The project site at Rabigh is located in western Saudi Arabia on the Red Sea, about 150km north of the port city of Jeddah.
Rabigh 2 IPP combined-cycle power plant will comprise three power plant units. For each of these units, Siemens is delivering two gas turbines, one steam turbine, and three electrical generators.
"This order is yet another indicator of the large demand in Saudi Arabia for efficient power generation solutions," said Thierry Toupin, CEO of Business Unit Gas Turbines and Generators at Siemens' Energy Sector.
"The Rabigh 2 IPP project expands our already strong market position in this country even further."
Siemens announced in 2012 and 2013 the major orders it won in Saudi Arabia to supply the Qurayyah IPP and Jazan projects with its F-class gas turbines.
Siemens said Saudi Arabia presents "vast market potential" for highly-efficient combined-cycle power plants.
To keep pace with and drive the nation's advancing industrialisation and economic development, the installed electrical generating capacity - about 70 gigawatt (GW) - is expected to double by 2020 to 140 GW.
