Hydropower facilities / Pumped storage power plants (PSP)

Tashlyk PSP

Tashlyk pumped storage plant on the Southern Bug River as part of the South-Ukrainian Power Complex (which also includes the South Ukrainian Nuclear Power Plant and Oleksandrivska HPP) was designed to cover peak loads in the southwestern part of the Interconnected Power System of Ukraine, as well as to provide reliable basic operation mode of South-Ukrainian NPP. Construction of the PSP began in 1981. The first hydrounit was commissioned in December 2006, the second - in August 2007. Works on the commissioning of the third hydrounit and completion of the first stage of Tashlyk PSP are in progress at the moment.
