Description for Gibe III (Ethiopia)

The design of this record breaking 250 m high RCC dam has proved to be one of the biggest challenges faced by our engineers to date. The hydropower plant with its full capacity of 1870 MW recently came on-line.

Main Features

  • RCC Gravity Dam (H = 250 m, L_crest = 620 m)
  • Reservoir (V = 14'700 Mm³)
  • Spillway (No. 7 gates, 12 x 17.5 m, Q = 10'600 m³/s)
  • No. 2 Headrace Tunnel (L = 1.0 km, D = 11 m)
  • No. 2 River Diversion Tunnels (L = 1.1 km, D = 14 m)
  • No. 1 River Diversion Tunnel (L = 1.1 km, D = 7 m)
  • Rockfill cofferdam with impervious geo-membrane (H = 50 m, L = 205 m)
  • Outdoor Power House (No. 10 Francis turbines, IP = 1'870 MW)
  • Transmission Lines (L = 3 km, 400 kV)
