ABB wins substation contract for Saudi Arabia’s first integrated solar project19 June 2016
Green Duba, the first integrated solar combined cycle (ISCC) power plant in Saudi Arabia, is currently under construction and scheduled for completion in 2018. Located in the country’s northwest, along the Red Sea coast, the power plant being developed by Saudi Electricity Company will deploy an innovative solution that integrates solar energy and natural gas firing to produce up to 600 MW of electricity, of which 50 MW will be via steam from a concentrating solar parabolic trough thermal array.
The adjoining substation will be constructed by SSEM-Initec Energia Consortium for National Grid Saudi Arabia. Under a contract worth $26 million ABB will design, supply and commission a 420 kV gas insulated switchgear substation (of the type pictured) for the plant, providing a compact solution while minimising environmental impact.
The plant itself will be supplied by GE, based on F-class gas turbines, a 7F.05 and a 7F.03, in combination with a GE steam turbine. To aid fuel flexibility, the 7F.05 gas turbine will be operating on condensate gas (its first use in Saudi as a turbine fuel) and the 7F.03 on natural gas, with Arabian Super Light (ASL) crude oil as backup. The generators, heat recovery steam generators, condenser, boiler feed pumps and a Mark VIe distributed control system will also be supplied by GE.
