Karakaya Dam and Hydroelectric Power Plant was built as a part of the Southeastern Anatolia Project (GAP) on the Euphrates River, 150 km from Diyarbakır, in the Ergani-Çermik-Çüngüş direction of Diyarbakır's Ergani district, 85 km from the Diyarbakır-Elazığ highway. It has a total installed power of 1800 MW with 6 generators, each of which is 300 MW, and its annual production capacity is foreseen as 7.5 billion kWh.
The construction of the Karakaya Dam and Hydroelectric Power Plant, located in the Euphrates Basin, started in 1976 and was put into operation in 1987 after its construction was completed.
The body volume of the dam, which was built as a single curvature concrete arch type, is 2 million m³, its height from the foundation is 173 m, and its crest length is 462 m. The lake volume at the maximum water level is 9.242 hm³ and the lake area is 282.780.500 m².
In the power plant, there are six unit blocks of 300 MW turbine-generator as separated by construction joints, an assembly block on the left side of the coast, and also a right side block on the right side of the coast. Each unit block contains the turbine-generator group, as well as the main transformer and auxiliary machinery electrical equipment.
