Chaunskaya CHPP is a 34 MW coal power plant in Chukotskiy Avtonomnyy Okrug, Russia. It is operated by JSC "Chukotenergo". Based on its capacity (estimated), it can supply roughly 43k homes (estimated). It ranks #494 of 678 Russia power plants by installed capacity. Commissioned in 1944, it is around 82 years old — an older, legacy facility. In context, coal supplies about 18.4% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
The public capacity above is the current source-record value. A 2026 tracker candidate lists 30 MW for Chaunskaya 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: C_REVIEW_MANUAL - recommended action: manual_review_only - confidence: unknown. 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 34 MW, Chaunskaya CHPP is below the median coal plant in Russia (340 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 69.7°N — which shapes how much energy it can produce and how its output varies through the year.

The #113 largest coal power plant of 127 in Russia by capacity.
Russia has 127 coal power plants in this dataset, together about 64,498 MW of capacity.
