Today we will talk about the most ambitious hydroelectric, the value of which is comparable with state significance. We learn what is the tallest dam in the world. Below are the top 6 of the biggest dams on Earth.

I - HPP, Jinping-1 in China

Today it is the tallest dam in the world, created by human hands. Its height reaches 305 m, and the length - 568 M. HPP, Jinping-1 was launched in 2014 and immediately got into the "Guinness Book of records", thanks to its impressive size. The construction of the dam began in 2005 and in 7 years was launched the first hydraulic motor at the station. 2015 was introduced last sixth Assembly. What distinguishes the hydraulic motors on the Chinese hydroelectric power plant from the rest of the powerful stations in the world, so is the capacity of the units. If the current power units are working at power 300 MW, we are talking about 600 thousand kW. It is also one of the most powerful dams in the world. The dam located in Sichuan province near the mouth of the river Yalong.

The Design of the dam was started in 1950, and only after 11 years was started its construction. It was completed only in 1972, the same year was made its gradual entry into operation: the first unit was launched in the same year, and the last one after 7 years. Thus, by 1979, hydroelectric power station worked at full capacity, providing 75% energy costs. In the year of produced electricity from the plant around 11 billion kWh Water for power plants are not only used to generate electricity, but also goes along the tunnels for irrigation of agricultural land.

Due To the fact that the Enguri HPP is composed of transitional hydroelectric power plant leading to the river Eristskali belonging to Abkhazia, here it is necessary the cooperation between the two countries. Thus, the Inguri gidroenergokompleksa consists of buildings of Georgian hydropower (dam, reservoir and part of the tunnel) and the Abkhazian part of the tunnel and hydroelectric facilities.
