A ceremony marking the commissioning of the tenth and final hydro turbine at Russia's Sayano-Shushenskaya hydropower plant marks the end of a five-year restoration process, owner JSC RusHydro announced this week.
With company officials on-site and Russian Federation President Vladimir Putin participating via television link, RusHydro (LSE: HYDR) launched the plant's Unit No. 2, raising Sayano-Shushenskaya's cumulative output capacity to 6,400 MW.
Unit 2 was the most damaged in a August 2009 accident that created an explosion and caused the plant's turbine room to flood, killing more than 70 and necessitating the eventual replacement of all its 10 generator units.
RusHydro began the first stage of reconstruction in 2010 by restoring four of Sayano-Shyshenskaya's least-damaged units and putting them into service.
The company then installed six new units between 2011 and 2013 before replacing the four rehabilitated units with entirely new ones over the course of the past year.
The restoration cost more than US$89.3 million, RusHydro said, and was financed entirely with its own funds.
"New equipment at the Sayano-Shushenskaya hydropower plant has enhanced performance characteristics that meet all safety and reliability requirements," the company said. "The useful life of the new units has been extended to 40 years and maximum efficiency now reaches 96.6%."
The new Power Machines-manufactured turbines are also fitted with a more efficient process protection system, which, RusHydro said, will automatically shut the unit down if it deviates from controlled parameters.
"I am sure that this work will lead to an improvement in the electricity supply for the Siberian region and that the Sayano-Shushenskaya hydroelectric plant will contribute substantially to the stable functioning of all the energy systems in the whole country," Putin said.
HydroWorld.com reported Power Machines had installed the last generator rotor in mid-October.
