The four units will be integrated at Saudi Electricity Company’s (SEC) Hail Power Plant in the central region of Saudi Arabia.

Foster Wheeler Environmental and Industrial Group chief executive officer Byron Roth said: "Foster Wheeler is pleased to supply these HRSGs for SEC’s Hail 2 project featuring our improved state-of-the-art design for vertical HRSGs."

In addition to designing and supplying the vertical design HRSGs, Foster Wheeler will provide advisory services for erection and start-up of the units.

The Hail 2 project includes the conversion to combined cycle of four existing Siemens SGT-2000 combustion turbines, firing Arabian light oil by adding one steam turbine and four HRSGs.

The conversion will boost the power output by 147 MW, without increasing the fuel consumption.

Foster Wheeler is a global engineering and construction company and power equipment supplier.
