Voith Siemens is to carry out rehabilitation and modernization of the three 4.5-MW vertical Kaplan turbines, which have a runner diameter of 4.8 meters. Upon completion in 2010, the installed capacity of the units, which were commissioned in 1956-1959, is to be increased 10 percent.
The 50-year-old hydro project was a technical milestone and the first Tisza River facility to create a reservoir and store water for irrigation. Subsequent construction of the 28-MW Kiskore project created another, larger reservoir.
Voith Siemens' Austria unit and Siemens RT of Hungary received a contract from Tiszaviz Vizeroemue in 2002 to refurbish 28-MW Kiskore. The plant's four 7-MW bulb turbines were upgraded from 2003-2006.
