PLANT DESCRIPTION

Al Shabab site, situated in the Ismailia Governorate, is home to the existing power facility of eight GE Frame 9E outdoor combustion turbine generators (CTGs) of 125 MW each, commissioned in 2011. A new project on the site involves two combined cycle modules, each configured with four combustion turbines from the existing units. Each turbine's exhaust gases go to its respective heat recovery steam generator (HRSG), resulting in four HRSGs and one 250 MW steam turbine unit. The net output of the new facility is 500 MW when burning natural gas in the CTGs without supplementary firing in the HRSGs. Steam from the HRSGs powers a 250 MW non-reheat condensing steam turbine generator, and the steam is then discharged into an air-cooled condenser. The power generated is stepped up through main transformers and supplied to the utility grid via a 220 kV overhead transmission line in the existing switchyard. The project utilized a multi-package system with eight contracting packages and purchase orders for equipment and services. The current switchyard has space for two spare bays suitable for the new steam turbine unit.
