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.
