Dam Body and Reservoir
The concrete dam body, with a crest length of approximately 200 metres and a height of 45 metres from the foundation, regulates the Körkün River and creates the reservoir required for hydroelectric generation.

Transforming the hydroelectric potential of the Körkün River into energy through comprehensive engineering structures.
Karakuz Dam and Hydroelectric Power Plant is a comprehensive energy investment with an installed capacity of 76 MW, developed on the Körkün River within the boundaries of the Pozantı and Karaisalı districts of Adana.
Designed to generate 276 GWh of energy annually, the project constitutes an integrated hydroelectric generation system comprising a concrete dam body, diversion and power tunnels, cofferdams, access roads, a surge shaft, penstock, powerhouse, switchyard and power transmission line.
Technical Project Scope
Integrated energy infrastructure extending from the dam to the national grid
For the Karakuz Dam and Hydroelectric Power Plant Project, all principal components of the hydroelectric facility were planned together to regulate the water, convey it to the power plant through an extensive transmission system and generate electricity using a high hydraulic head.
Diversion Structures
To safely divert the river flow during construction, inlet and outlet structures, cofferdams and a diversion tunnel measuring 6 metres in diameter and 321 metres in length were constructed.
Power Tunnel
Water stored in the reservoir is conveyed to the power plant system through an 11-kilometre-long power tunnel with an internal diameter of 3.1 metres, constructed using two tunnel boring machines.
Surge Shaft and Penstock
Located near the outlet of the power tunnel, the surge shaft—56 metres deep and 12 metres in internal diameter—regulates flow variations, while the water is conveyed to the power plant through a 1,580-metre-long penstock.
Powerhouse and Turbine Units
Two Pelton turbines in the powerhouse utilise an approximately 530-metre hydraulic head to convert the high-pressure energy of the water into electricity with a total installed capacity of 76 MW.
Switchyard and Power Transmission
Electricity generated at the power plant is transmitted to the national grid through a 154 kV switchyard and a 32-kilometre power transmission line.
76 MW total installed capacity of the hydroelectric power plant
276 GWh planned annual energy generation of the power plant
11 km power tunnel constructed using two tunnel boring machines
530 m approximate hydraulic head utilised by the Pelton turbines
Engineering Approach
A high-head hydroelectric generation system in challenging terrain
Karakuz Dam and Hydroelectric Power Plant is a large-scale hydroelectric engineering project that harnesses the water potential of the Körkün River through long tunnels, high-pressure conveyance structures and Pelton turbines.
All structures extending from the dam site to the powerhouse and the national electricity grid were designed through an integrated approach, taking into account the terrain’s topographical characteristics and the 530-metre hydraulic head. Approximately 2,000,000 m³ of earthworks and 160,000 m³ of concrete works were completed within the scope of the project.
