GE Integrates Solar Energy with Combined Cycle for Saudi Electricity Company in Duba
Saudi Electricity Company (SEC) has selected its long-time partner GE (NYSE:GE) for a project that marks Saudi Arabia’s first integration of a solar field with a combined-cycle plant and the first introduction of condensate as a gas turbine fuel.
The landmark project, the ‘Green Duba’ Integrated Solar Combined Cycle Plant, will be built in the northwestern part of Saudi Arabia, along the Red Sea coast, and has the capacity to generate the equivalent power needed to supply approximately 600,000 Saudi Arabia homes for a year.
“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 CEO of SEC. “We expect the plant to provide cost-efficiencies over its life cycle, along with the fuel flexibility and solar capabilities needed to support the Kingdom’s fuel conservation and renewable technology initiatives.”
The project is designed to generate up to 550 megawatts (MW) from the combined-cycle plant; the solar field will supply steam for an additional 50 MW. 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. SEC will tender separately the remaining balance of plant, solar field, civil works, erection, commissioning and testing.
