Orava

Orava hydroelectric power plant is located by the first large retention reservoir in the Váh catchment area with seasonal balancing of run-offs. This helps to catch storm waters from spring-time snow thawing and from summer-time storms and in winter improve the Váh river flow rates, thereby increasing the share of the electricity generated at all the lower-laying HPP´s over winter periods.

 

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.
