Streams that will be harnessed by this hydropower system pass through the area of the Mt. Mali Sharrit massif and comprise catchment areas of the Lumi Plavë River and its tributaries, among which the most important are the rivers Lumi Brod and Lumi Restelic, and the catchment area of the Lumi Çaljane River with its tributaries. Waters collected in this area are conveyed by common conveyance systems of the rivers Lumi Çaljane, Lumi Restelic and Lumi Brod to the planned reservoirs at the Lumi Plavë River (Plavë Reservoir) and the field Fusha e Llopushnikut (Brezna Reservoir).
The Zhur Hydropower System is divided into the following elements:
• conveyance of streamflows from Mt. Mali Sharrit,
• reservoirs,
• HPP Zhur I – conveyance system and powerhouse, and
• HPP Zhur II – conveyance system and powerhouse.
Conveyance of streamflows from Mt. Mali Sharrit,
• gravity headrace tunnels of a total length of some 13.1 km
• canal sections of a total length of some 7.08 km,
• 13 aqueducts (400 m)
• siphon (150 m).
Reservoirs:
• Plavë Reservoir – formed by rockfill dam 210 meters long, 41 meters high
• Brezna Reservoir – formed by sealing the sinkholes in field Fusha e Llopushnikut
HPP Zhur I
• headrace pressure tunnel 3,100 meters
• steel penstock 1,410 m long,
• HPP Zhur I powerhouse - above-ground type
HPP Zhur II
• closed canal 520 meters
• gravity headrace tunnel 1,835 meters
• open canal about 560 meters
• steel penstock about 152.40 meters
• HPP Zhur II powerhouse - above-ground type

Annual output (average) 342.20 GWh 55.39 GWh
Benefits from the HPP Zhur construction:
• annual power output of approx. 400 GWh produced by renewable inexhaustible resource (water), which does not contaminate abiotic components such as: air, soil and water, has no hazardous effects to human health, and which would consequently improve the annual electricity balance in Kosova,
• tertiary power system reserve
• coverage of the variable part of the daily diagram (peaking),
• ensuring continual sale of electricity along with major financial effects, or increase in value of less valuable energy produced in thermal power plants
• ensuring cold standby with minimum water loss (as necessary) and hot reserves for thermal power plant capacities,
• guaranteed supplies should electrical energy be exported,
• load frequency and power control
• environmental quality assurance and control,
• opening new jobs,
• improvement in conditions for day-trip tourism development,
• improvement in conditions for sports and recreation at the reservoir and in the hinterland,
• improvement in conditions for weekend resort development,
• improvement in conditions for development of angling,
• improvement in hunting conditions,
• possibilities for cage fish farming in the reservoirs.
