Knyazhegub Hydroelectric Power Plant is a 152 MW hydro power station in Murmansk, Russia. It is operated by PJSC "TGC-1". Based on its capacity (estimated), it can supply roughly 152k homes (estimated). It ranks #348 of 678 Russia power plants by installed capacity. Commissioned in 1955, it is around 71 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 16.7% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

In context: how this plant compares
At 152 MW, Knyazhegub Hydroelectric Power Plant is well above the median hydro plant in Russia (72 MW). Technically it is described as conventional storage. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 66.9°N — which shapes how much energy it can produce and how its output varies through the year.
