The Riyadh PP12 plant is located 100 km west of the Saudi capital. Once completed, the plant will produce a net output of 2,175 MW at high temperatures with high efficiency. The plant utilises exhaust gases from the gas turbines to generate steam and run the steam turbines, maximising the fuel utilisation with a highly efficient combined cycle design. The power plant is scheduled to enter commercial operation by 2015, in order to meet the increased demand expected in the central region.
This contract includes the supply of two 342 MW steam-turbine generator sets and eight Heat Recovery Steam Generators (HRSG) for the power plant. This is Alstom’s first steam tail offering for the Saudi Arabia market and the equipment is being offered in a novel integrated package, which will augment power output from the plant by an additional 4 MW.
Nader Abdellatif, Alstom Country President in Saudi Arabia said, “We are proud to be working with Bemco on this important infrastructure project for SEC and the country. Alstom offers leading steam tail technology which will extend the efficiency and performance of this power plant. We are pleased to further extend the relationship we have built with SEC through our work in the Shoaiba power plant with this project”.
Alstom has wide experience in adding steam tails to suit any class of gas turbines from any original equipment manufacturer. Across the Middle East, it has helped major energy producers improve plant efficiency with steam tail add-ons. Projects in the region include the steam tail for the Az-Zour gas-fired project in Kuwait which will add 400 MW to the existing plant capacity, the natural gas & heavy distillate (fuel oil) Damietta 1-3 power plant in Egypt for which Alstom added a steam tail with three 139 MW steam turbines, Dubai’s Condor/Kestrel 125 MW aluminium smelter complex in Jebel Ali for which Alstom supplied three 125 MW steam turbines. Alstom also added two 103 MW steam turbines to Pakistan’s Kot Addu residual Oil & natural gas power plant.
