. In total more than 1,500 individual plants and dozens of research institutes sent their equipment and specialists.

The first powerhouse came online on 22 December 1958, and the plant was fully declared complete on 10 September 1961. Technologically the station broke many new grounds. In 1959 a new Moscow-Stalingrad 500 kV high voltage line power came into operation. Several years later, for the first time in the world a new experimental 800 kV DC

 line Donbas-Volgograd was successfully tested and later became operational. During the 1960s and 1970s several new electrotechnical and hydromechanical machinery was tested on the station for the future Siberian and foreign stations.

Technical details

Today the station is the largest in Europe. It 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

, which is situated on the dam. In opposite to other static inverter plants, it has no harmonic filters.

Economical value

The new plant played a decisive role in the development of the Lower Volga region and the Donbas, as well as uniting the large energetic system of the Central, Volga, and Southern economic regions. The new dam also allowed for the Volga to become navigable, allowing for a path from Saratov

Ecology

One of the most negative results that the dam caused was that it disrupted the traditional path of Caspian fish migration to their breeding grounds. The most affected became the beluga

 industry. The fishery canal turned out to be inefficient, and from 1962 to 1967 the annual rate was 15% of the pre-dam.
The other major effect of the dam is that it formed one of the largest reservoirs, which amounts for a behemoth volume 31.5 cubic kilometres of water and stretches 540 km long, and up to 17 wide with a massive 3,117 square kilometre surface area. As a result numerous settlements and fertile lands were lost.
