GE has confirmed an order from Saudi Electricity Company (SEC) to supply turbines for the Kingdom’s first integrated solar and combined cycle (ISCC) power plant.

The landmark ‘Green Duba’ project will be built along the north Red Sea coast, and has the capacity to generate the 600MW, of which 10% will be produced using solar technology, to power roughly 600,000 homes.

“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 lifecycle, along with the fuel flexibility and solar capabilities needed to support the Kingdom’s fuel conservation and renewable technology initiatives.”

The SEC order includes 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, GE said in a statement, confirming reports which first emerged in Saudi press last week.

The company did not reveal the value of the order.

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.

The F-class gas turbines are the first to offer customers the ability to operate on ASL.

“The contract is another testament to our committed partnership with SEC to further enhance the efficiency and flexibility of its plants,” said Hisham Albahkali, GE’s President & CEO for Saudi Arabia and Bahrain.

“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 renewables.”

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, GE said in a statement. By early 2015, all eight units at PP12 will be operating in combined cycle and add nearly 2,000 megawatts.

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 approximately 40 SEC power plants—a partnership that spans over four decades.
