The project is also the first time condensate has been used as a gas turbine fuel. The ‘Green Duba’ Integrated Solar Combined Cycle Plant will be constructed in the north western part of Saudi Arabia, along the Red Sea coast and will have the capacity to generate enough power for around 600,000 Saudi 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 will generate up to 550 MW from the combined cycle plant with the solar field contributing an additional 50 MW. GE will supply the engineering equipment for the combined cycle plant, including two highly efficient 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 supply the remaining balance of plant incorporating the solar field, civil works, erection, commissioning and testing.
The GE-supplied 7F.05 gas turbine will operate on condensate while the 7F.03 will operate on natural gas with Arabian Super Light (ASL) crude oil as backup.
Hisham Albahkali, GE president & CEO for Saudi Arabia and Bahrain, said that the integration of solar power and the introduction of condensate fuel at the Green Duba project supports the government’s vision to promote energy efficiency with a focus on renewables.
