The Volga Hydroelectric Station or Volga GES, is the largest hydroelectric station in Europe and is the last of the Volga-Kama Cascade of dams, before the Volga River flows into the Caspian Sea. Today, it is operated by the electricity company RusHydro.

Volga Hydroelectric Station consists of a 725-metre long, 44-metre high concrete dam that crosses the Volga river. Supporting it is a 3250-metre long landfilled dam with a maximum height of 47 metres. The Station also offers railway and road crossings of the Volga.

The present power rating of the station is 2,582.5 MW and annual energy output of 12.3 billion KW-hours. There are a total of 22 generators. 17 generators produce 115 MW each (four of which have recently received repairs and overhauls), three produce 125.5 MW each and two produce 120 MW. Three fishery paths drive additional 11 MW units each, but at present two are not functioning. Thus the initial output is slightly downrated.

The 4.9 kilometre dam forms the Volgograd reservoir. At present the station is managed by OAO Volzhskaya GES that is owned by OAO GidroOGK, a daughter company of the state organisation RAO AES Rossii.

The generators of the power plant are connected to the power grid in a somewhat unusual way as the machine transformers of the generators serve also as inverter transformers of the static inverter plant of HVDC Volgograd-Donbass, which is situated on the dam. In opposite to other static inverter plants, it has no harmonic filters.

The Boguchany Dam is a large hydroelectric dam currently under construction on the Angara River in Kodinsk, Russia. The Boguchany Dam is a 2,587 m (8,488 ft) long gravity dam, which includes reinforced concrete 774 m (2,539 ft) long segment for power station building and temporal ship lock. The power station will consist of nine turbines with a capacity of 330 MW each. It will generate 17.6 TWh of electricity per year. Turbines are manufactured by Power Machines. The power station is built by and will be owned and operated by OAO Boguchanskaya GES, a joint venture of RusHydro and Rusal. The energy from the plant will be used, among others, by a large Boguchany Aluminium Smelter (to be launched in 2013).

The Sayano–Shushenskaya Dam is conventional hydroelectric power plant located on the Yenisei River, near Sayanogorsk in Khakassia, Russia. It is the largest power plant in Russia and the sixth-largest hydroelectric plant in the world, by average power generation. The full legal name of the power plant, OJSC [Open Joint-Stock Society] P. S. Neporozhny Sayano-Shushenskaya HPP [hydro power plant], refers to the Soviet-time Minister of Energy and Electrification Pyotr Neporozhny. The head of the power plant is Valery Kyari.

The Sayano–Shushenskaya hydroelectric power plant is operated by RusHydro. As of 2009, it was the largest power plant in Russia and the world's sixth-largest hydroelectric plant by average power generation. It provides more than a quarter of RusHydro's generation capacity. The plant operated ten type РО-230/833-0-677 hydro turbines manufactured at the Leningradsky Metallichesky Zavod, each with a capacity of 640 MW at 194-metre (636 ft) head. The total installed capacity of the plant is 6,400 MW; its average annual production is 23.5 TWh, which peaked in 2006 at 26.8 TWh.

The station's constructions include the dam, a power plant building located near the dam, and an additional spillway which is under construction. The arch-gravity dam is 245.5 metres (805 ft) high. It has a crest length of 1,066 metres (3,497 ft), crest width of 25 metres (82 ft), base width of 105.7 metres (347 ft) and maximum head of 220 metres (720 ft). It consists of a solid left-bank dam 246.1 metres (807 ft) long, a power dam 331.8 metres (1,089 ft) long, a spillway dam 189.6 metres (622 ft) long and a solid right-bank dam 298.5 metres (979 ft) long. It is by far the larger of only two gravity-arch dams in Russia. Water pressure for the dam is approximately 30 million tons, of which 60% is neutralized by the dam's own weight and 40% is carried to rock on the bank

The dam is constructed to "safely" withstand earthquakes up to 8 on the Richter scale, and was recorded by the Guinness Book of World Records for the strongest construction of its type.

The dam supports the Sayano-Shushenskoe Reservoir, with a total capacity of 31.34 km³, useful capacity of 15.34 km³ and surface area of 621 km² (240 sq mi).
