The Akbaş HPP project is at the downstream of the tandem Akkent-Çalkuyucak HPP along the Büyük Menderes River in Denizli’s Çal district. The project was completed and put into operation on 12.12.2013.

Located close to the Akkent-Çalkuyucak HPP, the project was designed to have a weir, around 3-km tunnel, forebay pool and a penstock (65 m head 1.5 m diameter). The plant is capable of handling 19.6 m³ water per second.

Project construction was undertaken by Kuzey İnşaat Makina A.Ş while electromechanical equipment was supplied by the ANDRITZ Hydro (France) & INDAR consortium.

Proposed annual energy production capacity of the plant is 45.5 million kWh.
