Background on Plant

The plant used to be owned by the Far Eastern Generating Company, which is in turn majority-owned by RusHydro. In September 2019 RusHydro agreed to an asset swap which would transfer ownership of the plant and the Luchegorsky coal mine to Andrey Melnichenko, the majority-minority owner of the Siberian Coal Energy Company (SUEK). In June 2020 the asset swap was completed with SUEK becoming the plant's owner and RusHydro obtaining 41.98% ownership of the Far Eastern Energy Company. Siberian Generation Company, part of SUEK, is managing the asset.

The nine-unit, 1,467-MW, mine-to-mouth Primorsky GRES power station (also referred to as the Luchegorsky Fuel & Energy Complex (LuTEK)) was built between 1974 and 1990. The plant is the largest in Russia's Far East, and its 330-meter Stack 3 is tied for the 14th tallest in the world.

In 2021, the plant generated 5,210 million kWh of electricity, in 2020 generation was 4,857 million kWh. In 2022, generation increased by 7% to 5,600 million kWh, driven by growth in demand from the industrial and residential sectors influenced also by a colder winter and emergency repairs conducted at two other power plants.

Modernization to increase generation

In 2021, SUEK announced plans for a large-scale modernization of the Primorsky power station, which would entail extensive repairs on all 9 of the station's power units. Work was scheduled to take place between April 2022 and April 2024. SUEK expected the modernization to "significantly increase the power generation capacity" of the power station, but did not provide a specific estimate.

In April 2021, modernization started at Unit 1; and in April, at Unit 6. This modernization was planned with a goal for the existing units to reach their projected capacities, since they have not been producing sufficient output (in some cases, for more than a decade) due to being outdated.

The modernization project was approved by Glavgosekspertiza in 2022, stating that it will allow the plant to increase its operating hours from the current 4,000h per year to 6,500h per year.

In its 2022 report on the plant, Siberian Generation Company reported that a major overhaul of turbine unit 4 was completed. Other major works included replacement of worn metal of wet ash collectors, gas intake shafts, dust systems, hot and and cold air systems and internal/external gas ducts. The cost of modernization amounted to RUB 5.2 bn. The report also mentioned planned increase in generation by 70% following the completion of the modernization program.(this is roughly consistent with the increase in working hours mentioned above).

In April 2023, Siberian Generation Company reported that modernization started on the largest unit 9, expected to take place over 8 months.
