Chaunskaya CHPP is a 34.5 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).

In context: how this plant compares
At 34.5 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.

Climate zone & how it works
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.
