KARAKUZ DAM & HYDROELECTRICAL POWER PLANT PROJECT

The Karakuz Dam and Hydroelectric Power Plant Project is located on the Körkün River within the boundaries of the Pozantı and Karaisalı Counties of the Adana Province. The annual energy production of the plant with an installed capacity of 76 MW is 276 GWh. The project consists of intake and outlet structures as well as derivation and energy tunnels, coffer-dams, access roads on either side of the lake, balance tank, penstock, power plant, switchyard and transmission lines.
The dam consists of a concrete body with a crest length of approximately 200 m and a height of 45 m from the foundation. The dam lake area is 29,9 hm² with a total volume of 5.112 hm³ and the access road around the lake is 6,2 km. The 321 m long derivation tunnel has a diameter of 6 m and the 11 km energy tunnel (Two TBMs (Tunnel Boring Machine) were used for the energy tunnel) has an interior diameter of 3,1 m. There are two Pelton type turbins in the power plant. The 154 kV switchyard was connected to the National Power Distribution System by a 32 km long energy transmission line.
