Buk Bijela HPP

The Drina River is the right and the biggest tributary of the Sava River and belongs to the Black Sea basin. It is created by the merging of the Tara and Piva rivers at Šćepan Polje. The basic area includes the Southwestern and Western part of the Republic of Serbia, the Northern part of the Republic of Montenegro and the Eastern part of the Republic of Srpska, stretching over an  area of 19 570 km2. The total length of the base is around 500 km, and its average width is 100 km. Annual precipitation in the upper part of the basin is 3000 mm, and the average precipitation in the entire basin is 1100 mm.

Buk Bijela hap is one of the hydro power plants planned in the system of hydro power plants on the upper Drina.

Basic technical data for the Buk Bijela Hydro Power plant

Buk Bijela HPP is a dam storage plant consisting of:

  • Gravitational concrete dam with a machine house,
  • reservoir.

Power N = 93.52 МW,

Production E = 332.34 GWh,

Installed flow Qi = 350 m3/s.

Gravitational concrete dam consists of four parts:

  • gravitational part of the dam with a mounting space on the left bank,
  • gravitational part of the dam on the right bank,
  • machine house with an intake house, discharge water and dividing wall which separates the discharge water from waterfalls,
  • evacuation facilities-spillway and deep discharge with segment dams and waterfall.

The total crown length of the dam is 197.3 m, of which the left gravitational part 68.1 m, the machine house 42 m, part of the dam with the bottom outlet 15.5 m, part of the dam with spillways 38.2 m, and the right gravitational part 33.5 m. The largest construction height is at the part of the machine house and is 57.8 m.

With its construction a reservoir with the normal water surface of 434.00 m above sea level is formed and with the total volume of 15.7 million m3. The useful volume is 11 mil. m3. Total reservoir length is around 11.5 km.

Three Kaplan aggregates are located in the machine house.

Two are dimensioned for the installed flow of 150 m3/s each, and one for water management minimum flow of 50 m3/s.

The amount of total investments is 196.14 million EUR.
