Background

The power station is owned by Donbassenergo which in turn belongs to EnergoInvest Holding (60.7%). 25% is owned by the State Property Fund. In September 2021, Donbassenergo commenced the bankruptcy procedure. Donbassenergo also used to own the Starobesheve power station.

Slavyansk power station was developed in two phases: five 100-MW sets followed by a pair of 800-MW units. They were built from 1954-1971, and are fuelled by coal, oil, and natural gas. By 2012, only two of the original units (Units 4-5) were still in service, with their capacity de-rated to 80MW, and one 800-MW unit (Unit 7) was also in service. Unit 6 had been decommissioned in 2003.

The 800 MW Unit 7 was damaged by shelling in 2014, and was restored to run at 400 MW in 2015.

In 2021, the power station was reported to have 880 MW of capacity, including 720MW of Unit 7 which has been restored after repairs. However, in a May 2021 interview, a spokesperson for Donbassenergo stated that only Unit 7, with 720 MW of capacity, was in operation, suggesting that the two 80 MW units at the power station had been mothballed.

The power station was forced to stop production in August 2021 and October 2021 due to lack of coal.

In February 2022, before the start of the war, it was reported that only one unit was operating at the station, presumably Unit 7.

War in Ukraine

In May 2022, the station stopped operating "in order to save the lives and health of the station staff". The area where the station is located has been under constant rocket and artillery fire from the Russian occupation forces.

On September 17^th, the plant was attacked by missiles and caught fire. A media article from September 2022 referred to Slavyansk power station as not being not operational.

In January 2023, Naftogaz concluded agreements with three power stations, including the Slavyansk power station, for the supply of gas. Later in June 2023 the station was referred to as having to operate on natural gas. It was therefore assumed that as of June 2023, Unit 7 was operational (the same unit that was in operation prior to the start of the war), using gas as fuel for the time being. It is not clear whether switching to gas is a temporary measure or a permanent one.

In December 2023, a media source stated that the residents of the northern part of Donetsk were left without electricity due to the fact that the automatic protection system was activated at the Slavyansk TPP.

Slavyansk power station II

Since 2013, Donbassenergo has planned for two new units of 330 MW each to replace unit 6 (also referred to as 6A and 6B), but has not yet secured permits or financing. The new units were included in "The plan for development of United Energy System of Ukraine for 2015-2024."

Local contractor Energoprogress is promoting the project together with U.S. company Babcock-Wilcox. Donbassenergo has already dismantled the old 800 MW unit of the original Slavyansk power station to prepare space for construction of the new unit 8.

With the site cleared and technical documentation completed, Donbassenergo was seeking finance for the project but finding it difficult, as the plant is near a combat zone between Ukraine and pro-Russian separatists.

In December 2018, it was reported that Donbasenergo signed a contract with China's Dongfang Electric International Corporation to build new units 6A and 6B at 330 MW each. The reported cost of the contract for the reconstruction using circulating fluidized bed (CFB) technology is US$684.296 million. According to the plan, unit No. 6A was to be put into operation in July 2022, unit No. 6B in July 2023.

In March 2020, American firm Ernst & Young announced that it would provide consulting services for Donbassenergo related to the Slavyansk II project, including securing necessary permits and arranging financing with the Bank of China, which was expected to cover 70% of project costs. At this time, Dongfang Electric was in the midst of the feasibility study. In November 2020, the construction of Units 6A &6B was included in the Cabinet of Ministers of Ukraine's list of priority investment projects for 2020-23.

In a May 2021 interview, a spokesperson for Donbassenergo stated that the company hoped to put Unit 6A into operation in 2025, and Unit 6B into operation in 2026.

As of December 2022, there were no indications that construction on Units 6A & 6B had begun, nor that the project had secured financing. In addition, given the situation in the region and the fact that Donbassenergo had initiated bankruptcy proceedings, the project was likely shelved.
