Power unit with world’s most powerful cogeneration turbine launched in Moscow Region

    • The reliability of heat and power supplies in Moscow and the Moscow Region has been enhanced.
    • All of the core equipment at the revamped power unit was manufactured in Russia.
    • The unit uses an intelligent system for analytical processing and remote monitoring.

The renovated power generating unit No. 9 at CHPP-22 operated by Mosenergo (part of the Gazprom Energoholding Group) was brought into operation today via a conference call during a briefing led by Alexey Miller, Chairman of the Gazprom Management Committee.

All of the core equipment at the revamped power unit was manufactured in Russia. For instance, the Т-250 steam turbine that has reached the end of its useful life is now replaced by a Т-295 turbine — a cutting-edge development in turbine construction by Russian engineers, it is the world's most powerful turbine in terms of combined heat and electricity generation for consumers.

The heat output of the Т-295 turbine can reach 372.9 Gcal/h, which is an increase of 13 per cent against Т-250. The new turbine's power output can reach 295 MW (up by 18 per cent) in the cogeneration mode (when electricity and heat are produced simultaneously) and 335 MW (up by 11.7 per cent) in the condensing mode (when only electricity is produced).

The Т-295 turbine is also notable for the fact that it marks the first time in Russia when pre-installed equipment was used for connection to an intelligent system for analytical processing and remote monitoring. By receiving information from turbine sensors, the system can detect and signal potential defects far in advance. This makes it possible to plan repairs ahead of time and prevent equipment failures.

Moreover, the power generating unit is equipped with, among other things, a new boiler unit that triggers the turbine and is designed to work with supercritical parameters of steam (565 degrees Celsius), as well as a modern hydrogen-and-water-cooled generator.

The power unit is controlled via a hi-tech automated process control system of domestic make. The system provides the full extent of the control, information and service functions that are required for the equipment to operate reliably in all working regimes.

CHPP-22 is the source of power and heat for southeastern districts of Moscow, as well as for the town of Dzerzhinsky and for most localities within the Lyubertsy urban district in the Moscow Region. There are active residential construction sites in the areas adjacent to CHPP-22.

The renovation of power unit No. 9 has strengthened the reliability of power supplies to the existing consumers and created a possibility for connecting new ones. After the renovation, the power unit can provide about 300–400,000 residents with heat. In addition, the energy efficiency of the CHPP has been increased through reduced specific fuel consumption and enhanced environmental performance.


The Т-250 turbine (manufactured by the Ural Turbine Works) is a legendary turbine made in the USSR which was developed for heat supplies to large cities of the Soviet Union. The first place of its installation was CHPP-22. T-250 turbines were manufactured from the early 1970s to 1992.

Mosenergo (Gazprom Energoholding Group) is the world's largest heat producer. Mosenergo comprises 15 active power plants which, inter alia, supply over 50 per cent of the electricity consumed in Moscow and the Moscow Region and cover about 90 per cent of Moscow's need for heat.
