In context: how this plant compares
At 50 MW, Chaunskaya-2 power station is below the median coal plant in Russia (340 MW). 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a polar tundra climate (Köppen ET) — Northern Hemisphere, latitude 68.8°N — which shapes how much energy it can produce and how its output varies through the year.
