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).

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.
