A new rotor wheel is delivered to the Ust-Ilimskaya HPP

A new rotor wheel has been delivered to the Ust-Ilimskaya HPP as part of the comprehensive New Energy program aimed at upgrading EuroSibEnergo's hydroelectric power plants. This is the second hydroelectric unit to be replaced at the fourth most powerful hydroelectric power plant in Russia.

The rotor wheel weights 86 tons and is 5.7 meters in diameter. It took almost a month to transport the rotor wheel from the plant in Saint Petersburg to Ust-Ilimsk. The rotor wheel was transported across Russia over a distance of about 7,000 kilometers using special motor vehicles.

Installation of the new rotor wheel will take three months; the second upgraded hydroelectric unit is scheduled to be put into commercial operation in February 2017. The turbine's efficiency will increase by 5.5% and reach 96.7%, which is one of the highest levels in the Russian hydropower industry. This will enable the Ust-Ilimskaya HPP to increase electricity output with the same volume of water passing through the turbines.

The replacement of rotor wheels at the Ust-Ilimskaya HPP began in April this year; in June, the first upgraded hydroelectric unit of the hydroelectric power plant was commissioned. Overall, from 2016 through 2018, four rotor wheels will be replaced at the HPP as part of the New Energy program.

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. EuroSibEnergo will invest RUB 15 bln in the program.

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.

Vyacheslav Solomin, CEO of JSC EuroSibEnergo:

"The New Energy program will enable more efficient use of Siberia's hydropower resources; it will help improve the reliability of our hydroelectric power plants and meet the demand of the economy for clean energy. We are convinced that it is these efficient, clean and innovative technologies that should form the basis of future power generation in Siberia."
