The idea of generating electricity in a module of composite units depends on burning fuel in gas units, and the steam produced used to operate the steam turbine through energy recovery boilers. This achieves the generation of additional energy equivalent to 1/3 of the total energy of the module and saves 1/3 of the amount of fuel used in comparison. The gas units run on natural gas fuel (basic fuel) and diesel fuel (alternative fuel). The installed units are connected to the unified electrical network through seven electrical circuits with a voltage of 220 K.
Al-Shabab Combined Cycle Power Plant
It is a combined cycle gas turbine (ccgt) power plant located in Ismailia, Egypt. The power plant run on dual-fuel. The primary fuel being used to power the plant is natural gas. In case of shortage of natural gas the plant can also run on Light Fuel Oil.
The station has been operating on a simple cycle system since 1982 through 3 gas units that were strengthened in 2011 by constructing 8 outdoor combustion turbine generators.
The new facility estimated 500 MW net output is achieved when burning natural gas in the CTGs with no supplementary firing in the HRSGs. The steam exhausted from the steam turbine is discharged into an air cooled condenser, implemented for the first time in Egypt and the Middle East region. Air is used for the power plant cooling demand.
Damietta Power Plant
The gas fired power plant was opened in the west of Damietta and got commissioned in 2015. It consists of four outdoor gas turbines with a total capacity of 500 MW. After converting it to a combined cycle station, the capacity of the station has increased to 750 megawatts while saving gas consumption by 35%. The power plant has a water-cooling system.
