Arabian Bemco Contracting Co. and GS E&C have selected Alstom Thermal Power for a contract worth over €100m to supply steam tail for the 2,175MW Riyadh PP12 gas-fired power plant. The thermal power plant located 100km west from the capital of Saudi Arabia is being constructed by the companies for the Saudi Electric Company.
Under the contract, Alstom will supply two 342MW steam-turbine generator sets and eight heat recovery Steam generators for the power plant, and equipment will be provided in a novel integrated package which will augment power output from the plant by an additional 4MW.
The plant uses the exhaust gases from the gas turbines to generate steam and run the steam turbines, and maximise fuel utilisation with a highly efficient combined cycle design. The power plant is expected to start commercial operation by 2015.
