Scheduled to be built in northwestern Saudi Arabia along the Red Sea coast, the 600MW Green Duba integrated solar combined cycle plant is expected to generate the equivalent power needed to supply 600,000 Saudi homes for a year.

Upon completion, the project will be the country’s first integrated solar plant and combined-cycle plant and the first introduction of condensate as a gas turbine fuel.

SEC president and CEO engineer Ziyad Bin Mohammed Al-Shiha said: "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.

"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 combined-cycle plant will generate up to 550MW and the solar field will provide steam for an additional 50MW.

Under the contract, GE will supply the engineering equipment package for the combined-cycle plant, which include 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.

A separate tender will be issued by SEC for the remaining balance of plant, solar field, civil works, erection, commissioning and testing.

GE Saudi Arabia and Bahrain president and CEO Hisham Albahkali said: "The integration of solar power and the introduction of condensate fuel at the Green Duba project is a true milestone for the Kingdom and supports the government’s vision to promote energy sector efficiency with a focus on renewable."
