Each turbine unit has an installed electric capacity of 420 MW, with efficiency of about 58%.
The construction projects for the CCGT units at CHPP-20 of Mosenergo and the Serov SDPP of OGK-2 were implemented using gas and steam turbines manufactured by Siemens, and exhaust heat boilers by Power Machines.
With the commissioning of the new turbine units, consumers in Moscow and the Serovo-Bogoslovsky energy hub are expected to receive reliable supply of energy.
Russian Minister of Energy Alexey Miller said: "Today for the first time in the history of Gazprom two new combined cycle gas turbine units with an aggregate capacity of 840 MW have been commissioned at once.
"All in all, since entering the power industry in 2007 Gazprom commissioned some 7 GW of new capacities so far.
"The commissioning of CCGT-420 in Moscow marks the completion of the Mosenergo investment program under the capacity supply agreements. Overall, seven cutting-edge combined cycle gas turbine units with an aggregate capacity of 2.9 GW (more than 21 per cent of the company’s total installed capacity) were built at Mosenergo power plants. Over the period of operation, combined cycle gas turbine units proved their production and economic efficiency, making it possible to save natural gas and significantly reduce air emissions."
Gazprom Energoholding, a completely-owned subsidiary of Gazprom, holds a controlling stake in Mosenergo, which operates CHPP-20 power plant and OGK-2, which runs Serov SDPP power plant.
