The Combined Cycle Power Plant, supplied by Ansaldo Energia SpA in Gebze/Turkey under the EPC Contract, consists of two Gas Turbines, two Heat Recovery Steam Generators and a Steam Turbine with a total generating capacity of 865 MWe.

Each Gas Turbine and Steam Turbine have seperate generators and step-up transformers from which electricity is exported via three 380 kV transmission lines to the TEIAS grid.

The Heat Recovery Steam Generators and Steam Turbine have three pressure levels and reheat system with an Air Cooled Condenser.

The Power Plant is supplied by natural gas coming from BOTAS national gas network.

Raw water is supplied by Izmit Municipal Water Company (ISU) via IMES OSB pipeline. In addition, there are two wells dedicated to the supply raw water to the Plant by a dedicated pipeline. The raw water is mainly used to make demineralized water on site.
