Saudi Electricity Co. (SEC) has selected its partner GE for a project that marks Saudi Arabia’s first integration of a solar power field with a combined-cycle plant and the first introduction of condensate as a gas turbine fuel.
The 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 about 600,000 Saudi Arabia homes for a year.
The project is designed to generate up to 550 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; 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.
In terms of fuel flexibility, GE has supplied the 7F.05 gas turbine to operate on condensate and the 7F.03 to operate on natural gas, with Arabian Super Light crude oil as backup. GE’s F-class gas turbines are the first to offer customers the ability to operate on ASL.
Recently, the first four 7F.05 gas turbines in the field successfully reached full commercial baseload operation at SEC Power Plant 12 in Riyadh. By early 2015, all eight units at PP12 will be operating in combined cycle and add nearly 2,000 MW.
Today, GE assists in the generation of more than half of the Kingdom’s power supply and has over 500 gas turbines installed in the Kingdom. GE equipment operates in about 40 SEC power plants—a partnership that spans over four decades.
With nearly 80 years of experience and 1,000 employees in Saudi Arabia, GE is expanding its energy presence in the country through knowledge-sharing initiatives and increased investments for technology centers that provide service, repair support and customer training in the power, water and oil and gas sectors.
