From the energy producing potential 66% belongs to the Danube, 10% to the Tisza and 24% for the other rivers.
At the moment there are 37 hydropower plants operating in Hungary – 24 of them in the west part of the country representing 50 MW capacity, producing 210 GWh/a with 51 hydrogenerators.
The biggest hydropower plants work on Tisza: Tisza I. at Tiszalök, with capacity of 12,5MW, and production of 45 GWh/a. It was inaugurated in 1954. The capacity of Tisza II. at Kisköre reaches 28MW, and produces 104 GWh/a in average.
On Hernád River –north-east part of Hungary – run several small plants with capacity about 0,5 Mw at Gibárt, Felsődobsza and Kesznyéte.
On Rába (Raab) River at Alsószölnök, Csörötnek, Körmend, Ikervár run some small hydropower plants with capacities several hundred kW. On some small rivulets – Lajta (Leitha) Kis-Rába, Pinka, Répce etc. – in the western part of Hungary coming from the slops of the Alps there are some small plants. Their capacity is very small and their existence gives mainly only a special flavor to the charming environment of the area.
The Gyöngyös River running from the highest peek of Hungary, from the Mátra Hill, gives power to 8 plants with capacities no more, than some dozen kW.
Two scenic creeks: Josva in the Bükk (North-East Hungary) and Séd in the Bakony (north of Balaton Lake) host two spectacular plants.
Because of the topography of Hungary, no hydropower plant has been built on the Danube, and new hydropower plants are seldom planned.
