Saudi Arabia is constructing its first supercritical thermal power plant—which are highly efficient and produce fewer greenhouse gases than conventional power plants. EPC contractor Hyundai Heavy Industries has selected Yokogawa Electric to supply control systems, safety instrumented systems, analysis systems and other products for the first stage of the Jeddah South supercritical oil-fired thermal power plant project.

Stage 1 of this project, being built by the state-owned Saudi Electricity Co., involves 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 a Centum VP R5 integrated production control system for the control of the boiler and its auxiliary facilities; PK200 current-to-pneumatic converters; a liquid analysis system consisting of conductivity, pH and residual chlorine analyzers; and a 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 distributed control systems (DCSs), safety instrumented systems (SISs) and plant information management systems (PIMSs), key components of the integrated production control systems. Yokogawa Electric and Yokogawa Electric Korea will be responsible for the engineering and delivery of the current-to-pneumatic converters and the analysis systems.
