For reconstruction put the last of the previously recovered Sayano-Shushenskaya HPP

The Sayano-Shushenskaya hydroelectric power plant began the reconstruction of number 3, which was put into operation after reconditioning station in December 2010. That was the last to be in service of the four, the least affected by the accident and restored in 2010. 

During the reconstruction of Energy will hold a complete replacement of the turbine, the turbine flow-examined and culvert, the press service of the company "RusHydro". Completion of the reconstruction unit is scheduled for the summer of 2014.

Recall commissioning in 2010, the four least affected hydroelectric (№ 3, 4, 5 and 6) made it possible in a short time to resume the operation of the station, which increased the reliability of the power system of Siberia and the possible transfer work spillway station in design mode. These units worked the basic version (free with a maximum load) without participating in the regulation of frequency and power flows in the system. Hydraulic unit number 3 after reconditioning generated more than 9.5 billion kWh of electricity, and all the restored station units — more than 40 billion kilowatt-hours

However, work is continuing on other station units. In the crater hydroelectric number 5 goes on the generator stator assembly, installation of water-cooled generator and water supply, and at the installation site is the rotor assembly and the upper bracket. Continuing dismantling of equipment and components hydraulic number 4, extracted for reconstruction in February this year.

After starting the hydraulic unit number 10 in April 2013 began the final stage of restoration of Sayano-Shushenskaya HPP. By the end of 2014, will be replaced by new ones, all four previously recovered hydro (№ 3, 4, 5 and 6), and put into operation the most affected during the accident hydraulic unit number 2.

As a result, in 2014 the Sayano-Shushenskaya hydroelectric power station will be equipped with a completely new and modern facilities, with improved performance and compliance with all safety and security requirements. The service life of the new units is increased to 40 years, with a maximum turbine efficiency of 96.6%. Improved its energy performance. Also turbines are equipped with a more efficient system of technological protections acting on the automatic shutdown of the unit.
