HEAT SUPPLY SERVICES. The introduction of the heating system in Leningrad is usually said to have appeared in 1924, when the first heating line laid from electric power station No.3 (104 Fontanka River Embankment) to building No.96 on the same embankment. The electric power station soon came to supply other residential buildings as well as bath-houses and public buildings. By 1931 Leningrad grid comprised five thermal power stations with the total capacity of 238 MW, the heat supply was equal to 130,000 Gcal a year, the length of the heat network of the centralized heat supply attached to 94 buildings amounted to 16 km. By 1941 the capacity of Leningrad thermal electric power stations reached 46 MW, and the annual heat supply totalled 930,000 Gcal. The length of the city heating network exceeded 70 km (supplying 500 residential buildings and municipal buildings). During the Siege of 1941-44 due to fuel shortage the centralized city heat supply stopped. The heat supply restoration works in Leningrad started in 1944, after the raise of the Siege. By the late 1955 the length of Leningrad heat network amounted to 142 km. A master plan of the city heat supply was developed in 1956. By 1967 all the thermal electric power stations started providing heating to consumers and were renamed into heating and power stations. By 1980 the centralized heating supply system in Leningrad covered 56% of residential and public utilities buildings, the heating supply of other consumers was provided by boiler-houses (24%), as well as block heating stations or in-building boiler rooms. The heating installations of buildings are mostly attached to the heating system network of Lenenergo. The hot-water supply is carried out by the direct distribution of water. The growing number of floors in buildings and the length of the main heating lines determined the change for the unrelated layout of heating services. By the late 1980s, according to the project of Leningrad Science and Research Project Institute, 200 central heat distribution stations with indirect heating units, pumps and mechanisms assigned for multi-storeyed buildings heating supply (for 14 storeys and higher) were built in Leningrad. The total length of St. Petersburg heating network as of 2002 comes to 6,055 km.
