Oşkan Dam and Hydroelectric Power Plant
Project’s Overview
The Upper Ceyhan Hydropower Project, also referred to as Oşkan Dam, is situated on the lower reaches of the Ceyhan River within the borders of Osmaniye province in the southern part of Türkiye. It is the first phase of a power station executed in the cascade development of two (2) infrastructure projects by a joint venture (JV), led by Özaltın Construction Company with its partner, Nurol Construction Company.
Construction of the Oşkan dam as a composite dam involved a 180,000 m3 earth embankment and a 158,000 m3 concrete structure spanning across the Ceyhan River valley. An overflow gated spillway with a concrete volume of 63,000 m3 is located in the river channel.
The spillway is flanked on one end by an earth embankment that extends to the right abutment. On the other end, the spillway abuts the 95,000 m3 concrete section which stretches to the left abutment and integrates the water intake into the powerhouse. The dam has a combined length of 305 meters and a structural height of 23 meters.
The power plant is located at the base of the dam. It is equipped with 3 pit-type horizontal axis Kaplan turbines, and their associated generators with an installed capacity of 25 MW. All three (3) units were fully commissioned, and officially inaugurated 2010. The hydroelectric project was completed within the time frame set by the contract.
