The facility is designed to include an indoor Power Block consisting of two 250 MW (nominal, ISO) combustion turbine generators (CTGs), each feeding exhaust gases to its respective unfired heat recovery steam generator (HRSG).
Steam from the two HRSGs will be fed to one 250 MW (nominal), single reheat and condensing Steam Turbine Generator (STG). The estimated facility net output will be approximately 750 MW (nominal, ISO).
This output will be achieved when burning natural gas in the combustion turbines with no supplementary firing in the HRSGs. Oxides of nitrogen (NOx) emissions will be controlled by dry low-NOx (DLN) combustors. An inlet air filtration system will be included to supply suitably filtered combustion air to the CTGs.
The steam exhausted from the steam turbine will be fed into a once-through cooling, single-pass and divided water box condenser. Power will be generated at manufacturer’s standard voltage in the CTGs and the STG, stepped up through main transformers, and fed to the EEHC National grid via a 500 kV, GIS switchyard. Water for the Power Plant cooling demand will be obtained from the Mediterranean Sea and discharged to the Mediterranean Sea.
