Akdere Hydropower Project is a diversion type hydropower project and located in Marmara Region within Inegol district of Bursa province over the creek of Akdere using the head between 500 m and 360 m.
According to the first feasibility report prepared in 2008, the project was designed such that it is composed of two diversion weirs, transmission channel, forebay, penstock and power plant. After carefully reviewing the project with the support of the office and field studies of Prosem Engineering, it is seen that by eliminating one weir, designing the transmission channel as GRP pipeline and burying it near the stream bed and transmitting the water directly to the turbines through this pipeline, the project would become faster, more economical and feasible. The projects have been changed accordingly and revised feasibility report has been prepared. These modifications reduced the undesirable social and environmental effects as well as cost of expropriations considerably. In order to keep the pressure rises at reasonable levels in GRP pipeline, “Pressure Relief Valves” (PRV) will be installed inside the powerhouse. It will be possible to generate energy at low regimes of flow with two large and one small Francis type turbines installed in the powerhouse.
