In February, energy minister Dubravka Djedovic Handanovic said that Serbia aims to build the Bistrica RHPP by 2031, adding the power plant in western Serbia will be the largest new energy facility in the country that will be of major importance for balancing and storing electricity output.
EPS said earlier that Bistrica RHPP will comprise four units of 628 MW in total installed capacity, with planned annual generation of some 1,100 GWh. The multipurpose facility will benefit from the operations of a pump-turbine unit. Its flexibility and storage capacity will significantly contribute to the security of power supply and decarbonisation of Serbia and the region.
Bistrica RHPP will be located on the Uvac/Lim river basins.
