Hydro power plant "Perućica"

HPP “Perućica” is the oldest large hydropower plant in Montenegro, and was put into operation in 1960. It is named after the well Perućica, which originates in the vicinity of hydroelectric power plant.

 It is located in the municipality of Niksic, in northern Bjelopavlici plain, while small hydro power plants are located in the municipalities of Kolasin, Podgorica, Cetinje and Savnik.

Its installed capacity is 307 MW, and a potential annual production is about 1,300 GWh. For electricity production, HPP “Perucica” uses water catchment of river Gornja Zeta, which is water that flows into Niksic field with favorable decline in the short distance between the Niksic field and Bjelopavlici plains. Useful reservoir is 225 million water cubic meters. Catchment area of HPP “Perucica” is 850 km².

HPP "Perucica" consists of the following facilities:

  • accumulations "Krupac" and "Slano" and retention "Vrtac"
  • The system of channels,
  • Sedimentation,
  • Compensation reservoir,
  • Intake tunnel with the intake structure,
  • Pipeline with three pipes under pressure,
  • Power house for 8 aggregate,
  • Electrical Substations of 110 kV and 220 kV,
  • Supply tunnel 3323.27 m,
  • Pipeline no. 3 with a diameter of 2.65 + 2.5 m.

In the machine building of HPP “Perućica”, seven twin turbine-type "Pelton" generators with the horizontal properties of the total installed capacity of 307 MW were built. Five units have installed capacity of 40 MVA and two of 65 MVA. It is planned that the eighth power generator of 65 MVA to be installed.

Between March 12, 1960 - December 31, 2016, HPP “Perucica” produced 49,008.93 GWh, which is approximately 898.80 GWh of electricity annually. In a record 2010 year, it was produced around 1,434.9 GWh.

HPP "Perucica" has in 2016 produced 938.73 GWh.

EPCG, in year 1992, began with the realization of the modernization process in HPP “Perućica”, which included work on the revitalization and modernization of production, bringing the plant equipment and facilities to a level that will reduce the risk of accidents and ensure safety of workers, and increase operational readiness to guarantee current production. This program, in the first phase, involved the reconstruction and realized hydro machines and electrical equipment to unit 1, 2, 3 and 4 and two home units.

Implementation of priority projects of reconstruction and modernization of hydro-mechanical and electrical equipment in units 5, 6 and 7 has been planned to take place within the second phase, in the period 2018-2022, together with the system of management of such units and integral information system at the plant's level, equipment of the water conveyance system and rehabilitation of super-elevation of the channel Opačica and reconstruction of Moštanica channel. The modern equipment for hydrological and hydraulic measurements will be installed. Afterwards, it is planned to reconstruct and modernize 110 kV switchyard and 220/110 kV transformer station.
