TGС-1 to Build Hot Water Boiler House in St. Petersburg

16 December 2020

TGC-1 PJSC will build a hot water boiler house at Power Plant No. 2 (PP-2) of the Centralnaya CHPP by 2027. The relevant order issued by the St. Petersburg Government was signed by the City Governor Alexander Beglov.

The commissioning of new facilities will increase the reliability of heat supply to over 200 thousand residents of the Central District of St. Petersburg and improve the environmental situation.

PP-2 as a source of heat supply has no alternative. The heat generated here is supplied to 1,740 buildings, including hospitals, maternity hospitals, educational institutions, and subway facilities. At the same time, the equipment commissioned in the first half of the 20th century is outmoded and physically obsolete.

Since it is impossible to modernize the old power plant buildings without turning off the heat supply, it was decided to build a new boiler house building. It will be located on the plant territory from the Novgorodskaya Street side.

The installed thermal capacity of the new equipment will be 730 Gcal/h.


The Centralnaya CHPP of TGC-1 PJSC was established on 21 July 1999 and unites the oldest power plants in Russia: PP-1 and PP-2. The CHPP provides electric and thermal energy to industrial enterprises, residential and public buildings of the Central, Moskovsky and Admiralteisky Districts of St. Petersburg. Today, about 500 thousand people receive heat from the Centralnaya CHPP, and the generated electricity is supplied to the unified energy system of Russia. The plant’s installed electric capacity is 123 MW; installed heat capacity is 1,410 Gcal/h.

TGC-1 PJSC (part of the Gazprom Energoholding Group) is a leading producer and supplier of electricity and heat in the North-West of Russia. TGC-1 comprises 52 power plants within four constituent entities of the Russian Federation: St. Petersburg, the Republic of Karelia, and Leningrad and Murmansk Oblasts.
