The combined-cycle power plant is a next-generation facility. Four 9 FA gas turbines, four waste heat boilers designed to generate steam, two steam turbines and other equipment will be installed at the new power plant. 

The coefficient of performance (COP) of a simple-cycle power plant is 34.2 per cent on average, the COP of a combined-cycle power plant is about 57 per cent. The amount of natural gas used to generate 1 kilowatt of electricity will be reduced significantly: from 380 to 216 grams. Combined-cycle power plants are attractive in ecological terms, as the volume of combustion products, namely carbon dioxide, emitted in the air per unit of energy produced is reduced. 

The 1,574MW power plant will allow increasing the capacity of the Mary state power plant by more than 2 times that will become the largest energy enterprise in the region.
