Background on Plant

The station is owned by Kumertautskaya TeTS LLC that used to be owned by Bashkir Generation Company, but was sold to Sverdlovsk Energogazovaya Company («Свердловская энергогазовая компания») for 84.7 million roubles in 2016. However in 2020 the ownership changed and as of May 2023, 90% of the company belonged to Kumertau Briquette Factory and 10% to the municipal company Lokomotiv. In May 2023, the 10% municipal share was sold to Stroy-Region.

The power station began operations in 1954. It consists of 2 turbine units and 4 boiler units, connected through a cross-link system. Both operating turbines have capacity of 60 MW.

The power station is unique as it is capable of burning natural and waste gas, fuel oil, coal, production wastes of the briquette factory - "sludge" as process fuel, and a renewable fuel source such as granulated husk - sunflower processing waste from oil extraction plants.

The main fuel used to be lignite coal from Bashkortostan. In 2021 the company reported that 32% of the fuel requirements came from natural gas, 25% from associated gas, 38.2% from lignite coal and 4.7% from sunflower husk.

In 2022 the fuel balance changed in favour of gas with 67% of the fuel requirements covered by natural gas, 13.8% by associated gas, 19.2% by lignite coal and 0.2% from sunflower husk.

The plant produced 429 million kWh of electricity in 2021 and 409 million kWh in 2022.

Coal suppliers in 2021 were Orenburgugol JSC and Promtechugol LLC. In 2022 - only Promtechugol LLC.

The power plant was loss-making in 2021 and 2022 due to insufficient tariffs and accumulating debt levels.

Potential Retirement

A media article from October 2022 referred to the planned closure of the plant, with a project to decentralize the heat supply and build several module boiler houses run on natural gas. It appeared that the project was endorsed via a decree by the government of the Republic of Bashkortostan in May, 2022 and should have commenced in October 2022. A concession was planned to be awarded to build the boiler houses.

However, the System Operator's document published in early 2023 did not list the planned retirement of the plant, with both 60 MW units expected to remain. A media source from May 2023 further described changes to initial plan to retire the plant, stating that for now it will remain operational while the construction of the bloc-modular boiler houses may be undertaken as needed.
