Dalešice Hydro Power Plant


Dalešice Hydro Power Plant on the Jihlava River is a large power plant in the Czech Republic that has four Francis turbines with a nominal capacity of each and a total capacity of. The old turbines before the 1999–2007 reconstruction had a capacity of each. The plant includes the lower Dalešice-Mohelno Dam.

Dalešice Dam

Dalešice Dam lies in the Czech Republic. It was built between 1970 and 1978 together with the Mohelno Dam as a water source for the nearby Dukovany Nuclear Power Station. As it has the fastest-starting turbines of all dams in Czech republic it also acts as emergency source in case some of the reactors in Dukovany shut down. Thanks to the turbine capability to act as pumps it also plays significant balancing role for distributing network when it pumps water back to the higher reservoir during the night, and uses it again to produce electricity during the daily consumption peaks. The gravity dam is high, so the reservoir is also the deepest in the Czech Republic. The reservoir has a capacity of.

Mohelno Dam

The Mohelno Dam is through-flow dam, acting as the lower reservoir of the Dalešice-Mohelno pump-dam complex. The gravity concrete dam is long, 7.75/32 m wide and 38.65 m tall. It creates 7-km-long lake and has total capacity of. It includes single Kaplan turbine and single Francis turbine. In case of total blackout, the Mohelno turbines can jumpstart the Dalešice Francis turbines and together start the Dukovany NPP. Thanks to this the whole Dalešice-Dukovany complex is certified for fully autonomous operation independent of the external distribution network.
