Hydropower facilities / Hydropower plants (HPP)

Kaniv HPP

Kaniv HPP is the second stage of the cascade on the Dnieper River and wasbuiltin 1963-1972.

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.

During the 1st stage of rehabilitation 2 hydro units were reconstructed.Furthermore,high-voltage circuit breakers and current transformers of 330 kW have been partially reconstructed.  Other 22hydro units and remaining electrical and auxiliary out-dated equipment are being reconstructed 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.
