Vilyuiskaya HPP (HPP-1 HPP-2) is a 680 MW hydro power station in Sakha, Russia. It is operated by PJSC "Yakutskenergo". Based on its capacity (estimated), it can supply roughly 681k homes (estimated). It ranks #113 of 678 Russia power plants by installed capacity. Commissioned in 1970, it is around 56 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 680 MW, Vilyuiskaya HPP (HPP-1 HPP-2) 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.

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 63.0°N — which shapes how much energy it can produce and how its output varies through the year.
