Hydropower facilities / Pumped storage power plants (PSP)

Kyiv PSP

Facilities of Kyiv PSP were built from 1963 to 1975. The underwater part of the powerhouse and erection bay was built before pounding of Kyiv HPP reservoir in 1964. The first hydro unit of Kyiv PSP was commissioned in 1970. The rest of facilities were built up to 1976.

Kyiv PSP includes six hydro units: three turbines and three pump-turbines

Since 1996, the complex rehabilitation of the Dnieper cascade of HPPs has started.  The rehabilitation included reconstruction and replacement of hydropower, electrical, and auxiliary, mechanical and sanitary equipment of the HPPs. From 1997 till 2002 the first stage of rehabilitation was completed; and in 2006 the second stage of rehabilitation started.

The main goals of rehabilitation were to extend the operational period of the hydropower plants, to increase their capacities, output, reliability and safety, to fulfill the requirements of environmental protection, to improve the quality of electricity produced due to the improvement of control system, to create modern working conditions that meet current regulations.

Electrical equipment (generator circuit-breakers and modular switches as well as generators and modules electrical protections) was partially reconstructed during the 1st stage of rehabilitation. Reconstruction of three non-reversible hydro units (Nos. 2,4,6) during the 2nd stage of the Rehabilitation will lead to efficiency increase. Furthermore, the remaining out-dated electrical and auxiliary equipment is also under reconstruction at the 2nd stage.

Scope of work envisaged under the contracts:

  • rehabilitation feasibility study (Iand II Stage);
  • rehabilitation program elaboration for rehabilitation design of the HPP
  • rehabilitation design of the HPP;
  • approval of technical part of bid documents for equipment supply;
  • detailed design engineering on equipment renovation and hydro structures reconstruction;
  • co-ordination of design solutions on civil work and on technological equipment modernization;
  • design supervision over rehabilitation.
