CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

Background
The plant is owned by Rusatom Infrastructure Solutions, part of Rosatom group.[1] Rusatom Infrastructure Solutions manages the asset since 2014. The company was created specifically with the objective of managing the energy assets in cities where Rosatom has operations.
The power plant supplies electricity and heat to the city of Seversk and to Siberian Chemical Factory.[2][3]
The plant was commissioned in 1953 and its equipment was installed until 1961. Since then the plant had been working as is with some modernization in the mid-1980s and then in the early 2000s.[4]
Multiple Units
Older sources refer to the plant having 15 turbine units and 18 boilers[3] as well as higher capacity of 699MW.[4] But a source from June 2022 referred 449MW of installed capacity and 10 turbine units.[2] The System Operator's document published in early 2023 listed the plant's units and capacity of 399MW as of January 2023 with 8 installed units (page 33).[5] This includes three 100MW units and several smaller units below 30MW of capacity.
Unit 6 with 50 MW and Unit 12 with 100 MW were retired in May 2022, while a new Unit 13 with 100 MW was commissioned at the same time to replace Unit 12.[6][5][7] Thus, installed capacity decreased by 50MW from 449 MW to 399MW as of 2023.[5]
Modernisation
In 2020, Rosatom took the decision to modernise the plant within the next 5 years, investing more than RUB 8 billion (ca 133 million).[2]
2 turbine units were planned to be replaced.[2] The new generators produced by Elektrotyazhmazh-Privod (Lysva, Perm region) were already delivered on site in April 2022.[8] Production of turbines was under way, 30MW each, with scheduled delivery in August and November 2022.[8] According to the System Operator's document from 2023, Units 1 and 2 with 25 MW each will be replaced by 2025 with backpressure steam turbines of 30MW each.[5]
As for the boilers, 6 boiler units of the first stage were to be decommissioned and 10 boilers of the second stage were to be modernized by changing the dust preparation system, installing automatic control system and partial replacement of the heating surfaces.[8] All equipment is Russian and it will be more compact and economical, thanks to better fuel efficiency as well as transition to a cheaper coal grade (unknown). The program should be completed by the end of 2025.[2]
Conversion to Gas
The plant was historically coal- and gas-fired. In 2018 a plan to transition to mostly gas was mentioned as part of the modernization programme.[9] In 2018, coal contributed 79% to the plant's fuel balance, gas 20% and heavy fuel oil 1%.[9] In February 2023, it was mentioned that the plant currently uses 85% gas and 15% coal.[10] Therefore it appeared that full conversion to using gas was in progress.
