Saudi Electricity Company (SEC) has selected 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.”
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 (ASL) 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 (PP) 12 in Riyadh. By early 2015, all eight units at PP12 will be operating in combined cycle and add nearly 2,000 MW.
