TGC-1 in St. Petersburg and Leningrad Oblast

The Nevsky branch currently has the bulk of TGC-1 JSC’s production capacities. The branch includes 10 cogeneration plants and 7 hydro power plants.

History of Development of the Region’s Energy Industry

The era of electricity in St. Petersburg began in the 1870s. At that time, Alexander Lodygin developed an electric lamp, Pavel Yablochkov’s “Russian Light” conquered Paris, experiments were being set up to transmit electric energy over a distance, and in St. Petersburg, the design of lighting of Liteiny Bridge was going full speed ahead, and the first electric power plant was being constructed at Okhta gunpowder factories.

In 1883, St. Petersburg Administrative Board issued a concession to Siemens-Halske for lighting Nevsky Prospect, and 32 electric lamps were lit for the first time on the section from the Admiralty to Anichkov Bridge. The electric lamps were supplied from electric power plants on barges moored at the Moika and Fontanka berths. At the same time, electric power plants in Tsarskoe Selo and Vasilievsky Island were constructed, and so-called house electric power plants became popular. In 1897-98, three central electric power plants appeared at once.

In 1906, Heinrich Graftio designed and a year later commissioned the Streetcar power station. Fifteen years later, on October 8, 1922, the first thermal power plant in the USSR, Red October, was commissioned in Petrograd.

In 1918, construction of Volkhovskaya hydro power plant began. The hydro power plant was opened in 1926, and reached full design capacity in a year. With the startup of this hydro power plant, commissioning of a number of substations, and a 35 kV cable feeding ring, a system for electricity distribution and electric power plant control from a central control station was created.

Nizhne-Svirskaya hydro power plant was founded in 1927 and commissioned in 1933. At the same time, the Svir-Leningrad 220 kV electric power line was commissioned, which was the first power line ever built completely with domestic equipment.

In 1929, the Centralnaya cogeneration plant was upgraded, and powdered coal began to burn in the boiler furnaces of the Soviet Union. In 1933, Dubrovskaya state district power plant was commissioned as the nation’s first electric power plant built entirely by Soviet specialists. All of its equipment was manufactured by domestic factories.

Post-War Period

After reconstruction, Vasileostrovskaya cogeneration plant became the first cogeneration plant combining electricity generation based on industrial and household district heating. In 1950, construction of Narvskaya hydro power plant began, and five years later the plant was commissioned to its full capacity of 125 MW. Construction of this hydro power plant solved the problem of electricity supply to Leningrad, Leningrad Oblast, and the Estonian Republic. In 1955-1958, three more cogeneration plants were commissioned: Pervomaiskaya, Avtovskaya, and Vyborgskaya. The period of intensive development of the Leningrad power and heating grid in 1970-1980 was associated with construction of the Severnaya and Yuzhnaya cogeneration plants with 100 and 250 MW heating units.

TGC-1 in St. Petersburg Today

In St. Petersburg and Leningrad Oblast, TGC-1 together owns 11 CHPPs, 1 HPP and 2 cascade plants: Ladozhsky and Vuoksinsky. The hydroelectric potential of the region is contained in the reserves of the Narva, Vuoksa and Volkhov rivers. The total capacity of the region’s plants is more than 4,000 MW of electric energy and around 12,000 GCal/hour of thermal energy.

In 2006, the Pravoberezhnaya CHPP was commissioned. In 2009-2010, two new turbine units were commissioned at Vyborgskaya and Vasileostrovskaya CHPPs, and four new hydroelectric generating units at Volkhovskaya, Svetogorskaya and Lesogorskaya hydro power plants.

In 2011, TGC-1 commissioned a new hydroelectric unit at Lesogorskaya and Svetogorskaya HPP of the Vuoksinsky Cascade, and a new CCGT unit at the Pervomayskaya CHPP was brought into operation in St. Petersburg.

Construction of the new CCGT unit at Yuzhnaya CHPP was completed.
In 2012, the company continued reconstruction of the Vuoksinskiye HPP Cascade with installation of a new (6 of 8) hydroelectric generating unit at the Lesogorskaya HPP. In St. Petersburg the new turbine unit of Pravoberezhnaya CHPP operated with a capacity of 450 MW.

Currently, the company is carrying out work for technical upgrading and reconstruction of primary equipment and is commissioning advanced process control, supervisory control, and communication systems.
