GE steam turbines to upgrade Saudi Arabia natural gas plant

Riyadh, Saudi Arabia, March 27, 2012—GE won a contract for nearly $200 million to supply steam turbine technology, power generation services and distributed control systems for the conversion of Saudi Electricity Co.'s PP10 power plant from simple to combined-cycle operation.

The project will add 1,300 MW to the plant's capacity to support the growing power requirements of Saudi Arabia's central region and help the country meet summer peak demands.

GE will now provide 10 of its SC series steam turbines specifically for the PP10 combined-cycle expansion. GE previously supplied 40 7EA natural gas turbines for the PP10 site. The combined-cycle conversion enables the plant to increase its output without any increase in fuel, boosting its operating efficiency.

In addition to the SC series steam turbines, GE will supply new balance-of-plant mechanical and electrical equipment. An existing simple-cycle Mark Vle integrated control system will be expanded to incorporate the entire combined-cycle plant. GE power generation services will include installation, testing, commissioning and completing the combined-cycle conversion.

Shipment of the GE equipment is scheduled to begin in the first quarter of 2013, with services to start in the second quarter of that year. The first two combined-cycle blocks at PP10 are scheduled to begin commercial operation in the second quarter of 2014, in time to meet summer peak demands, while the full combined-cycle plant will be online by the first quarter of 2015.

The Riyadh PP10 site recently entered commercial operation in simple-cycle mode and is adding about 2,000 MW to Saudi Arabia's grid to support the country's electricity demand and increase the power capacity in SEC's Central Operation Area by 20 percent.
