The Chirkei hydro power plant is situated on the Sulak river and is the largest HPP in the North Caucasus and the highest arch dam in Russia.
Those who get there can have a good excursion program about the plant. Also it’s a nice place to photograph.
The Sulak river basin is located in Dagestan. The water from the river is supplied to Makhachkala and Kaspiysk.
The Chirkei HPP is a part of the Sulak hydroelectric system and is its first step. Other steps are:
Miatlinskaya HPP and the complex of Ð¡hiryurtskiye hydro power plants.
Surface area of the reservoir – 42.4 km Â², and the volume reaches 2.78 km Â³.
The HPP construction began in 1964 and lasted for fourteen years.
The gantry crane at the crest of the dam is used for opening / closing the valves that regulate the water flow to the main hydro generators.
This is a view from the gantry crane. The dam is only six meters (about twenty ft) wide on the top. The construction seems to be so fragile from there!
This is a photo from the Google maps.
The water flows at a very high speed to the spiral chambers of hydraulic units.
