The Dalešice waterworks was built as a part of the nearby Dukovany Nuclear Power Station project. It includes the Dalešice water reservoir with the capacity of 127 million m3 of water, the Mohelno equalization basin, the Dalešice Pumped-Storage Hydroelectric Power Station, and the Mohelno run-off-river hydroelectric power station.

The pumped-storage hydroelectric power station is equipped with four sets of reversing Francis turbines (112.5 MW ea) for a 90 m head. Synchronous generators with 13.8 kV voltage and two-way rotation are used in both the turbine and storage pumping operation. The generator voltage is transformed to 420 kV outgoing voltage by unit transformers. Total capacity is 2,300 MWh.
