PLANT DESCRIPTION

Consists of two modules, each delivering 1500 MW of power (750 MW each). Each module includes two 250 MW combustion turbine generators (CTGs) that feed exhaust gases to their respective heat recovery steam generators (HRSGs) without supplementary firing. The steam from the HRSGs then feeds into a 250 MW reheat, condensing steam turbine generator (STG). To control Nitrogen Oxide (NOx) emissions, dry low-NOx (DLN) combustors are used. Filtered combustion air is supplied to the CTGs through an inlet air filtration system. The steam exhausted from the steam turbine goes through a one-through cooling, single-pass, divided water box condenser. The power generated by the CTGs and STG is stepped up through main transformers and transmitted to the national grid via a 500 kV and a 220 kV conventional switchyard. The Nubaria Canal provides cooling water for the plant. The contracting plan for the project involved a multi-package system, with 22 contracting packages and purchase orders procuring the necessary equipment and services.
