A new rotor wheel is delivered to the Bratskaya HPP

As part of a comprehensive program titled "New Energy", which is aimed at upgrading EuroSibEnergo's hydroelectric power plants, a new rotor wheel was delivered to the Bratskaya HPP on August 15. This is the twelfth hydroelectric unit to be replaced at the third most powerful HPP in Russia.

The rotor wheel weighs over 75 tons and is 5.5 meters in diameter and about 2.5 meters high. It took over a month to transport the hydroelectric unit from the manufacturing plant in Sankt Pölten (Austria) to Bratsk. First, the rotor wheel was delivered to Saint Petersburg by water; then it was loaded on a special motor vehicle and transported to the Angara Region at a slow speed not exceeding 60 kph.

Commissioning of the new equipment will help improve the performance of the hydroelectric unit and, consequently, boost electricity output at the Bratskaya HPP.

The New Energy comprehensive HPP upgrade program of EuroSibEnergo involves large-scale overhauls and replacement of main equipment at the Company's three largest HPPs in Siberia: the Krasnoyarskaya, Bratskaya and Ust-Ilimskaya HPPs. This will include upgrades of hydroelectric units and replacement of rotor wheels, transformers and outdoor switchgears at the HPPs.

Following the completion of the first stage of the New Energy program, by 2018 EuroSibEnergo's HPPs in Siberia will increase environmentally friendly electricity generation by 1.5 TWh per year, while water consumption will remain unchanged. The impact of upgrading existing HPPs is comparable to construction of a new 400 MW HPP in Siberia. This will enable partial replacement of coal-fired generation with hydropower, saving up to 800,000 tons of coal per year and reducing greenhouse gas emissions from coal-fired power plants by 2 mln tons per year, which will have a positive impact on the environment in various regions of Siberia.

In the course of HPP upgrades, EuroSibEnergo will use primarily domestically produced equipment.

About the Bratskaya HPP

The Bratskaya HPP is the third largest hydroelectric power plant in Russia (with a capacity of 4,500 MW). The first hydroelectric units at the HPP were put into operation in 1961, and in 1967 the HPP started operating at full capacity. Since its launch, the Bratskaya HPP has generated over a trillion kilowatt-hours of electricity; this would be sufficient to provide energy supply to the entire Russia, from Kaliningrad to Vladivostok, for as long as a year.
