Yokogawa Electric Corp. has received an order from Hyundai Heavy Industries Co. Ltd. to supply control systems, safety instrumented systems, analysis systems and other products for Stage-1 one of the Jeddah South supercritical oil-fired thermal power plant project in Saudi Arabia.

Jeddah South will be Saudi Arabia's first supercritical thermal power plant and is being built by a state-owned enterprise, the Saudi Electricity Co., at a site south of the city of Jeddah, which is on Saudi Arabia's western coast. Stage-1 of this project involves the construction of four 723 MW units producing a total of 2,892 MW. Unit 1 is scheduled to start operation in 2017.

For each of the four units, Yokogawa will supply:

  • Centum VP R5 integrated production control system for the control of the boiler and its auxiliary facilities, including all IEC61850-based electrical systems, a ProSafe-RS safety instrumented system (SIS), an Exaquantum plant information management system (PIMS), and a plant operation training simulator.
  • PK200 current-to-pneumatic converters.
  • Liquid analysis system consisting of conductivity, pH and residual chlorine analyzers.
  • Duct gas analysis system consisting of oxygen, infrared gas and TDLS200 tunable diode laser analyzers.

Yokogawa Saudi Arabia, a subsidiary of Yokogawa Middle East & Africa, will be responsible for the engineering and commissioning of the DCSs, SISs and PIMSs. Yokogawa Electric and Yokogawa Electric Korea Co. Ltd. will be responsible for the engineering and delivery of the current-to-pneumatic converters and the analysis systems.

Supercritical thermal power plants are highly efficient and produce fewer greenhouse gases than conventional power plants. It is expected that more plants of this type will be constructed in Saudi Arabia and other countries.
