Replacement of rotor wheels starts at the Ust-Ilimskaya HPP

As part of a comprehensive program titled "New Energy", which is aimed at upgrading EuroSibEnergo's hydroelectric power plants, replacement of rotor wheels of hydroelectric units has started at the Ust-Ilimskaya HPP, the fourth most powerful HPP in Russia.

The first new rotor wheel has already been delivered to the Ust-Ilimskaya HPP. The wheel weighs 83 tons and is 5.7 meters in diameter; it has been manufactured by JSC Power Machines. 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 about two months; the start of full-scale operation of the first upgraded hydroelectric unit has been scheduled for June 2016. The turbine's efficiency will increase by almost 5% to 96.7%, which is one of the highest levels in the Russian hydropower industry. This will enable the Ust-Ilimskaya HPP to boost electricity output without increasing water consumption.

Overall, from 2016 through 2018, four rotor wheels will be replaced at the Ust-Ilimskaya HPP as part of the New Energy HPP upgrade program of EuroSibEnergo.

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. JSC Power Machines will be one of the key partners in the program: the company will supply new rotor wheels for the Krasnoyarskaya and Ust-Ilimskaya HPPs and high voltage transformers.

"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," commented Vyacheslav Solomin, CEO of EuroSibEnergo.
