Surgutskaya GRES-2 is a 8,865 MW gas power station in Khanty-Mansiyskiy Avtonomnyy Okrug, Russia. It is operated by PJSC "Unipro". Based on its capacity (estimated), it can supply roughly 10.0 million homes (estimated). It ranks #1 of 678 Russia power plants by installed capacity. Commissioned in 1979, it is around 47 years old — long-established. In context, gas supplies about 44.7% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

The public capacity above is the current source-record value. A 2026 tracker candidate lists 5,742 MW for Surgut GRES-2 power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
Capacity claim grade: D_REJECT_KEEP_MASTER - recommended action: keep_master - confidence: rejected_candidate. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.
The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

At 8,865 MW, Surgutskaya GRES-2 is well above the median gas plant in Russia (200 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 61.3°N — which shapes how much energy it can produce and how its output varies through the year.

The #1 largest gas power plant of 338 in Russia by capacity.
Russia has 338 gas power plants in this dataset, together about 145,594 MW of capacity.
