Keban Dam and Hydroelectric Power Plant was built in one of the narrowest gorges of the Euphrates, 10 km downstream of the confluence of the Karasu and Murat rivers, located 45 km northwest of Elazig. Keban Dam and Hydroelectric Power Plant, with an installed power of 1330 MW (4x157.5 MW+4x175 MW) and an annual electricity generation capacity of 6.6 billion kWh, is one of Turkey's first giant investments in terms of energy. When it was founded, it alone met 20% of the electricity produced in Turkey.
The preliminary works of the Keban Dam and Hydroelectric Power Plant, which was built on the Euphrates River, is a project that dates back to the 1930s. The foundation of the project, which started in 1963, was laid in 1965. 4 units (Keban-1) of the power plant, the construction of which was completed in 1974, were commissioned in the same year and 4 more units (Keban-2) were added to this in 1982 and started to serve with a total power of 1330 MW.
Keban HEPP undertakes the task of flood control in the region with its dam lake as well as electricity generation. Besides contributing to the development of fisheries, the dam also provides the opportunity for local people to cross the lake by ferry for transportation to Ağın district of Elazığ, Pertek and Çemişgezek districts of Tunceli, and facilitates transportation. The Euphrates River, on which the power plant is built, has different flows at various times of the year.
Keban Dam is a mixed dam consisting of two different types of dams. The body volume of the dam, which was built in concrete weight and rock fill type, is 16,679,000 m³, its body height is 210,86 m, and its crest length is 1,125,72 m. Keban Dam Lake is the second largest artificial lake in Turkey with its 125 km length, 675 km² lake area and 29,408 hm³ volume. When listed together with natural lakes, it is in the 4th place after Van Lake, Salt Lake and Atatürk Dam Lake.
