Kráľová

Located by the Kráľová reservoir, the Kráľová hydroelectric power plant is the last large HPP on the Váh river featuring two installed sets having a maximum usable flow of 210 m3.sec-1 each, i.e. the Kráľová HPP 420 m3.sec-1 in total. With a total installed capacity of 45 MW, the power plant makes use of the Váh river section from the town of Sereď to the town of Šaľa.

 

Hydroelectric plants

Slovenské elektrárne operates 31 hydroelectric plants. Their combined output is 1,652.7 MW, representing approximately 38.4% of the Company’s total installed capacity. Majority of the installations is located on the Váh River cascade, or the longest river in Slovakia. On average, the hydroelectric sources generate 2,070 MW annually (consumption of pumped storage power stations excluded), or some 11% of the electricity produced by Slovenské elektrárne.

Because of their very variable power output and operational flexibility, hydroelectric plants are capable to satisfy the swiftly changing demands in the daily-load diagram, pairing nicely with the base load supply covered by nuclear power plants. Slovenské elektrárne has 736.6 MW installed in river hydropower plants and 916.4 MW in pumped storage power stations.
