Binary CC units were designed in Russia during 1990-1995.

Detailed description of CCUs is provided below.

Combined cycle unit CCU-450Т. Northwest thermal power plant, commissioned in 2000 in St.-Petersburg, is the first power plant in Russia, equipped with large combined cycle units of binary type (CCU-450Т) with high efficiency, unreachable in steam turbine units. The efficiency of power unit CCU-450T in a condensing mode makes more than 50 %, fuel consumption rate is more than 85 %, and power generation to thermal consumption ratio is more than 1300 kW.h/Gcal.
