Beyhan Dam and HEPP
Project’s Overview
The Beyhan Dam, with its hydroelectric power plant, is located on the Murat River, a tributary of the Euphrates in Elazığ province, Türkiye.
The operation has involved the construction of a 1,350,000 m3 Roller-Compacted-Concrete (RCC) gravity dam with an integral water intake, and penstock encasement that have a conventional concrete volume of 101,000 m3. The dam is 97 meters tall from the foundation, and has a crest length of 521 meters, including an ogee spillway with a discharge capacity of 10,500 m3/s. An excess of 214,000 m3 of conventional concrete (CVC) was used to build the 3-bay spillway, which is furnished with 6 Tainter gates, on a solid foundation at the right abutment.
The river diversion works comprised three tunnels with lengths of 535 meters, 572 meters and 582 meters, respectively. They were drilled, using the traditional method, through the left canyon of the river to a diameter of 11 meters. They were each concrete lined to a finished diameter of 9.5 meters.
The construction also involved the foundation, the tailrace excavation, as well as river channel dredging, carried out for the power plant, which is positioned at the base of the dam. Nearly 228,000 m3 of concrete was poured from start-to-finish to erect the powerhouse. The plant houses four (4) vertical axis, Francis- turbine-generator units. While three (3) units are rated at 183.5 MW each, one small unit is rated at 31.6 MW. In unison these four units reach a power capacity of 582.10 MW.
