Expansion in 2011

Expansion of the power plant involved the construction of two ≈400 MW units by December 2011, costing nearly RUB 19 billion, which increased its original capacity of 4800 MW to 5597.1 MW. The two new blocks do not use dried oil gas as is the case in the other six generators. They consume natural gas as a fuel, utilizing combined cycle, with overall efficiency rates of 56%. General Electric is the manufacturer and supplier of the generators.
