Sakhalin GRES-2 power station is an operating power station of at least 120-megawatts (MW) in Ilyinskoye, Tomarinsky, Sakhalin, Russia with multiple units, some of which are not currently operating. It is also known as Сахалинская ГРЭС-2.

Project-level coal details

  • Coal source(s): Solntsevsky coal complex



The power plant is owned by Sakhalinenergo, a subsidiary of RusHydro.

Phase 1 with 120MW was commissioned in November 2019.[2][3] The power plant was originally planned to begin construction in mid-2014 to be completed in 2016. Construction on Phase 1 began in March 2015, with Mosenergo as the construction contractor.[4][5] The project experienced construction delays, with completion postponed several times.[6][7][8][9]

Sakhalinskaya GRES-2 has two units with 60 MW capacity. Turbines were supplied by Ural Turbine Factory, generators by ELSIB and boilers by Krasny Kotelshchik. GRES-2 uses the latest generation of electrostatic precipitators that capture 99.6% of ash particles.[3] The circulating water supply system eliminates the discharge of wastewater. A unique feature of the station is the use of a "dry" cooling tower 65 m high, which has no analogues in Russia. Unlike conventional cooling towers, where a significant portion of the water evaporates into the atmosphere, in a "dry" cooling tower, water loss is eliminated.[3] The plant uses lignite and bituminous coal from Sakhalin coal mines (Solntsevsky coal complex).[10][11]

The new Sakhalinskaya GRES-2 has replaced the aging Sakhalin GRES-1 power station which is located on the east coast of Sakhalin, about 120 km to the northeast.[10] The remaining capacity of 84MW at Sakhalin GRES-1 power station was retired in December 2019.

Sakhalin is an isolated energy system and the two plants of Sakahlinenergo - Sakhalinskaya GRES-2 and Yuzhno-Sakhalinskaya-1 power station - cover 78% of the power needs of the island (as of 2021).[12] More than 50% of demand comes from the housing sector.[12] The generating capacities of the large oil and gas projects on the island are not connected with Sakhalinenergo's network.[12]

The plant produced 362 million kWh of electricity in 2020 and 356 million kWh in 2021.[12] According to RusHydro's annual report, the state-of-the-art plant was expected to produce 840 million kWh annually, covering a third of Sakhalin's demand for electricity.[13]

In 2021, an assessment of the construction process of Sakhalin GRES-2 found that state customers had "overpaid" for the project by RUR 18 billion. RusHydro also had to pay a penalty to the Federal Budget due to the three-year completion delay, amounting to RUR 244 million.[14]

Fire Incident

In April 2022, there was a fire at the power station which caused it to be temporarily shut down. In May 2022, the first unit was returned into operation, while the second unit was still under repairs, with expected return to operation scheduled by the start of the winter season.[15] The second unit returned to operations in October 2022.[16]


As of June 2019 and November 2022, there was no further news about Phase 2 or Phase 3 of the project, they appear to be cancelled.
