Saudi Electricity Co. (SEC) has selected General Electric (NYSE:GE) for a project that marks Saudi Arabia’s first integration of a solar field with a combined-cycle power plant, and the first introduction of condensate as a gas turbine fuel.
The Green Duba Integrated Solar Combined-Cycle Plant will be built in the northwestern part of Saudi Arabia, along the Red Sea coast. The project will generate up to 550-MW from the combined-cycle plant; and the solar field will supply steam for an additional 50-MW.
“This part of Saudi Arabia is a developing region with limited grid interconnection, so the additional power generated by the Green Duba project will be tremendously important in supporting growth,” said Eng. Ziyad M. Alshiha, president and chief executive officer of SEC.
GE will supply the engineering equipment package for the combined-cycle plant, including two highly-efficient, reliable F-class gas turbines, a 7F.05 and a 7F.03; steam turbine; generators; heat recovery steam generators (HRSG); condenser; boiler feed pumps; Mark VIe distributed control system and a long-term service agreement.
Recently, the first four 7F.05 gas turbines in the field successfully reached full commercial operation at SEC Power Plant (PP) 12 in Riyadh. All eight units at PP12 will be operating in combined cycle and add nearly 2,000-MW by early 2015.
