Summary

Gözeler – I HEPP, Gözeler – II HEPP and Gözeler – III HEPP are run-of-the river type hydroelectric facilities which will be constructed over the Murat River. They are placed from upstream to downstream as Gözeler – I HEPP, Gözeler – II HEPP and Gözeler – III HEPP respectively and the planning studies are ongoing.

At the upstream of these projects, Lower Kaleköy Dam, Upper Kaleköy Dam, Alpaslan – II Dam and Alpaslan – I Dam are located. From these projects, only Alpaslan – I Dam is in operation. At the downstream of Gözeler Projects, Beyhan – I Dam, Beyhan – II Dam and Keban Dam are located. Keban Dam is in operation.

Although there are several reservoirs in the upstream, because of the excessive flood potential of Murat River, spillway design discharges will be also very big. The fill body of the projects planned in the formerly feasibility report, were changed by Prosem Engineering and designed as RCC (Roller Compacted Concrete) body. By this means the spillway design discharges were reduced from probable maximum flood (9162 m3/s) to Q500 (4200 m3/s). Spillway design discharges were determined according to memorandum of State Hydraulic Works (DSİ).

By taking the advantage of the long axis and the downstream and upstream project belonging to Kalehan Energy also, the spillways of these projects were designed as uncontrolled. Thus, there will be no need of dozens of spillway gates.

Since the low head and high flow characteristics of these projects, Bulb turbines were preferred. The streambed levels at the downstream of the projects have been lowered up to 8 – 10 m resulting in a drop in the tailwater levels. In this way, the amount of agricultural lands laying under water is reduced and the negative social effects and expropriation costs are minimized.
