Tomsk region energy system is one of the crucial branch of region economic. In 2016 a Schematic model and programm of energy system development for 2017-2021 period adopted.
Electricity distribution through the region territory is carried out by electric networks with voltage from 0,4 kV to 220 kV. With neighboring power systems the area is connected via VL 500 and 220 kV:
- with Krasnoyarsk power system: 500 kV Overhead Line Itatskaya - Tomskaya;
- with Kuzbass power system: 500 kV HVL Novo-Anzherskaya - Tomskaya, 220 kV VLNK Novo-Anzherskaya - Vostochnaya, the 220 kV overhead line Novo-Anzherskaya - Zonalnaya, the HV-line 110 kV Yashkinskaya - Suranovo; VL 35 kV Zarya - Voznesenka;
- with Novosibirsk power system: VL 110 kV Boyarskaya - Chilino with a branch to the substation Kandaurovskaya.
Power grid also has a connection with the UES of Ural (Tyumen power system) over the two-circuit 220 kV HV line Nizhnevartovskaya GRES - Sovetsko-Sosninskaya.
Total length of HVL 110 kV and above is 7619.5 km (in single-circuit version). One PS 500/220 kV with installed capacity of autotransformers 1002 MVA and 104 110-220 kV substations with installed capacity of 7,669.3 MVA transformers is operated on the region territory.
The main system-forming line of Tomsk power system is a two-chain overhead line 220 kV Tomsk-Volodino-Parabel-Soviet-Sosninskaya over 770 km long. Due to the large length and low throughput, this line can not serve as a transit line for the parallel operation of the unified energy system of Siberia and the united power system of the Urals. Currently, the point of separation of electric flows of these power systems is PS 220 kV Parabel, thereby consumers of Tomsk region north of this substation receive electricity from Tyumen energy system.
Main entities of power industry forming the regional energy system of Tomsk Region are following:
- Tomsk branch of AO TGC-11 managing three energy sources, namely, Tomsk GRES-2 (Pnom of 331 MW), Tomsk TETs-3 (Pnom of 140 MW) and Tomsk PRC (Pnom of 14.7 MW);
- AO Siberian Group of Chemical Enterprises managing 549 MW thermal power plants and corresponding 35-110 kV overhead lines;
- Branch of PAO FSK EES. Tomsk PMES is managed by the PAO FSC EES MES of Siberia. The branch operates 220-500 kV grids. The power system is connected to the united power system of Siberia through the 500 kV grid and with the united energy system of the Urals through the 220 kV grid. The length (the length of the Tomsk double-circuit 220 kV overhead line Parabel - Nizhnevartovsk GRES is 807 km), poor connection with Tyumen energy system and lack of redundancy are considered major disadvantages of the backbone network;
- PAO Tomskaya raspredelitelnaya compania is managed by OOO ERDF Vostok. The company operates company-owned 35-110 kV grids that distribute electric energy to regional consumers. The distribution grid is constructed by circumferential and radial connections. The company encompasses mainly regional center grids and three territorial directorates.
In 2016 Shinguinskaya GTES (24 MW) with 4 units of 6 MW each had put into operation at oil and gas industry facilities.
In the power grid complex of the region, a number of facilities were reconstructed, which made it possible to increase the reliability of power supply to region's consumers and create a reserve of transformer capacity to connect new consumers. Work on monitoring and assistance continued in the implementation of: technical re-equipment of 220 kV Sovetsko-Sosninskaya substation, construction and reconstruction of electric networks of PAO TRK.
Within the framework of the investment program of PAO FSC EES, measures have been completed for comprehensive reconstruction of the 220 kV substation Sovetsko-Sosninskaya. Also 3 autotransformers with a capacity of 63 MVA each were replaced, for units with an installed capacity of 125 MVA each, which significantly increased the reliability of consumers in oil and gas sector of economy and create a reserve for connecting new consumers.
At the largest system-forming substation in the region - the 500 kV Tomskaya substation - measures to replace oil circuit breakers with modern gas-insulated ones have been completed, which ultimately will affect the reliability and quality of power supply for consumers in Tomsk region.
At present Severskaya APS with total capacity of 2300 MW is being constructed in Tomsk Region.
At present gas supply of a part of residential areas in Tomsk Region is provided with natural gas from the backbone gas pipeline Nizhnevartovsky Gas-Processing Plant – Parabel – Kuzbass and with liquefied gas from liquefied gas reservoirs and cylinder units. The gas supply of energy facilities – boiler rooms in towns of Strezhevoy and Kedrovy – is provided with associated gas of oil deposits. The network natural gas is supplied from 22 gas distribution stations (hereinafter – GDS), the average load of which does not exceed 40%.
As of January 1, 2017 about 2,214 km of gas pipeline branches are operates by OOO Gazprom gazoraspredeleniye Tomsk.
Currently, 38,835 households (apartments) had gasified with natural gas and 16,269 households - liquefied gas (LPG). In 2016 realization of natural gas to Tomsk region consumers amounted to 2.3 billion m3, which is higher on 1.7% than the consumption in 2015.
Through Tomsk region gas transmission system, taking into account its own consumption and transit to other regions, it is ensured a transportation of natural gas in volume of about 10 billion m3, of which about 3.5 billion m3 was produced in Tomsk region.
Tomsk region enterprises produced liquefied petroleum gas (LPG) about 152.5 thousand tons. Sales of OOO TD Tomskoblgaz to Tomsk region consumers amounted to 974 tons.
