It will take about five days to connect heat throughout the city.

The heating season has begun in Moscow. This was announcedSergei Sobyanin during a visit to the combined heat and power plant (CHPP-20) of PJSC Mosenergo in the south-west of the capital.

“There is a sharp cold snap, so we made a decision from today to start up heat in all social and cultural facilities and the residential sector,” he said. “I hope it will be warm at all sites for five days.”

According to Sergei Sobyanin, in-house heating systems, trunk networks, as well as gas and water supply systems are fully ready for the winter season.

Information about the beginning of the heating season can be obtained by calling a special hotline by phone: +7 (800) 100-23-29.

All buildings and structures of Moscow were prepared for the heating season of 2021/2022 – a total of about 74 thousand objects, including 34.1 thousand residential buildings, 8.8 thousand social facilities, 30.8 thousand economic objects. The infrastructure of the fuel and energy economy is also ready:

– thermal power plants (13 thermal power plants, 178 thermal power plants and boiler houses);

– heating networks (17 thousand kilometers) and heating points (22.4 thousand);

– gas networks (7.5 thousand kilometers) and gas control equipment;

– power grids (122 thousand kilometers), substations (21.2 thousand) and power centers (163);

– water supply networks (13.2 thousand kilometers), sewerage networks (9.3 thousand kilometers).

The CHPP has formed the necessary reserves of reserve fuel: 378.6 thousand tons of fuel oil, 360.4 thousand tons of coal, 24.9 thousand tons of diesel fuel.

19 thousand units of municipal equipment have been prepared for cleaning yards, roads and other seasonal works.

Snow disposal will be provided by 38 mobile snow melters and 56 stationary snow-melting stations. Their total capacity will be 635 thousand cubic meters of snow per day.

To eliminate damages on heating, electrical and other networks, 1,429 emergency teams can be involved, over 1,400 emergency power supply sources and three mobile boiler houses have been prepared.

The existing power supply capacities of the city make it possible to provide consumers with heat stably and uninterruptedly when the outside air temperature reaches minus 30-40 degrees.

CHPP-20 provides heat and electricity to 13 districts

CHPP-20 of PJSC Mosenergo was commissioned in 1952. It is located at 13 Vavilova Street. The combined heat and power plant runs on natural gas. It provides electricity and heat to 13 regions of the south-west and center of Moscow (Akademichesky, Gagarinsky, Lomonosovsky, Obruchevsky, Donskoy, Dorogomilovsky, Danilovsky, Yakimanka, Zyuzino, Kotlovka, Konkovo, Cheryomushki, Zamoskvorechye) with a population of 1.5 million people.

In 2015, the construction of a new CCGT-420 combined cycle power unit was completed at CHPP-20. Vladimir Putin gave the command to put the unit into operation on December 22, 2015 via video link.

The installed electrical capacity of the CCGT-420 power unit was 418 megawatts, then it was increased to 445 megawatts. The efficiency in condensing mode is about 58 percent. The main equipment of CCGT-420 includes gas and steam turbines, as well as a waste heat boiler.

As a result of the modernization, the electric capacity of CHPP-20 increased by 1.5 times – up to 1110 megawatts. The thermal power of the station is 2,557 gigacalories per hour.

An automated environmental monitoring system has been introduced at CHPP-20, which allows monitoring the level of emissions in real time and transmitting data to the State Budgetary Institution “Mosecomonitoring”.

To reduce nitrogen oxide emissions, smoke exhausters were installed on the power boilers of the station, and a two-stage fuel combustion was implemented. Old burners have been replaced with new ones that fully meet modern environmental requirements.

Silencers are installed on the boilers of the station; the noise level is monitored regularly at the enterprise.

CHPP-20 employs 516 people, one third of whom are engineers and technicians (174 people).

Since 2017, the Museum of the History of Mosenergo and Moscow Power Engineering has been operating on the territory of CHPP-20, which is an educational platform for schoolchildren, students, power engineers and a meeting place for industry veterans.
