DEFINITION AND OBJECTIVE OF THE PROJECT Oskan Regulator and Hydroelectric Power Plant is located 14 km to the northwest of Osmaniye Province, within the borders of Duzici District and on the Ceyhan River. The approximate head is 21 m between the upstream Aslanta ş Dam and HEPP and downstream Cevdetiye Irrigation Regulator. This head is planned to be utilized through upstream O şkan HEPP and Berkman HEPP. With an installed power of 3x10 MW, Oskan HEPP will generate 109,93 Gwh/year in total, 49,09 Gwh/year of which is reliable. Turkey is a rich country in terms of hydroelectric energy sources. However, only 11% of annual capacity estimated to be 108,5×10 9 can be used. This is nearly the half of our total annual energy consumption while the rest of it is provided from thermal sources and abroad. Berkman HEPP and upstream O şkan HEPP planned together are two plants which will be established in order to make use of the 21-meter head between Cevdetiye Regulator and Aslanta ş Dam on Ceyhan River. Total annual energy generation of the two regulators, each of which have 10,5 m heads, is 219,86 Gwh. This generation occupies an important place within Ceyhan Basin. Inasmuch as the state sector has to undertake investments of large dams, the authority to establish and operate the facilities bearing the quality of this type of “River type Power Plants” which do not require investment was granted to the private sector on 19/12/1984 with Law No. 3096. Oskan HEPP feasibility works desired to be conducted by benefiting from this law are carried out by TEMELSU Muhendislik Limited Şirketi (TEMELSU Engineering Limited Company). OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 4 BOZAT INC. 1. NON-TECHNICAL REPORT SUMMARY The construction of Oskan Regulator and Hydroelectric Power Plant on Ceyhan River in the Duzici District of the Province of Osmaniye is planned by the “PARTNERSHIP OF ÖZALTIN İNŞAAT T İCARET VE SANAY İ A. Ş-NUROL İNŞAAT VE T İCARET A. Ş.” The closest settlement unit to the project area is Karagedik Village, which is approximately 1,5 km away. Oskan HEPP is a plant which will be established in order to make use of the 21-meter head between Cevdetiye Regulator and Aslanta ş Dam. Construction stage of the project is expected to be completed in 3 years. Area of the facility to be established remains outside the borders of adjacent area. While 100 persons will be employed at the construction stage of the Hydroelectric Power Plant, 5 persons will be employed at the operation stage. Within the scope of the project, general needs such as food, shower, WC etc. of the employees at construction stage will be provided from the prefabricated site building to be set up and the same needs will be met at the power house building at the operation stage. Economic life of the facility is reckoned to be 30 years depending on the changing and advancing technology. With the hydroelectric power plant constructed through this project, energy requirement of the Region that cannot be met will be satisfied to a large extent. With the advancing industrialization, the need for energy, which is already scarce, increases. For this reason, energy requirement of the industrialists and the whole region will be largely met thanks to the HEPP to be constructed.

PROJECT SPECIFICATIONS a) Capacity of the Project and the Area Covered by the Project etc. Oskan Regulator Project area is approximately 14 km to the northwest of Osmaniye Province, upstream of Cevdetiye Dam and around Karagedik Villages. Coordinates of location of Berkman Regulator are 37° 24' north latitude and 36° 57' east longitude. In terms of topographical appearance, the land looks like Çukurova in regions between the sea and slopes that face onto the sea and like typical Central Anatolia in upper parts. Total basin area is 14.775km 2. With an installed power of 3×10 MW, Oskan HEPP will generate 109,93 Gwh/year in total, 49,09 Gwh/year of which is reliable. Properties of Oskan Hydroelectric Power Plant are given in Table-2.a.1. OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 6 BOZAT INC.

Development of these sectors gives rise to new energy and water requirements. Ceyhan River emerges as one of the closest sources to consumption centres. The most significant facilities among the ones that have been put into operation on Ceyhan River is Aslanta ş Dam and HEPP. This facility carries the purpose of irrigation, flood protection and energy and has an installed power of 3x46MW. Its elevation from the base is 95m, elevation from riverbed is 78m and it is an earth fill-type dam. Kartalkaya Dam planned for irrigation is on the Aksu branch of Ceyhan River, is in operation also. This earth-fill type Dam has an elevation of 57 m from the base while it is 56 m from the riverbed. Menzelet Dam, which is in operation, has an elevation of 150,50 m. from the base and it is 130,50 m from riverbed and it is rock fill type. Power plant of Menzelet Dam planned for irrigation and energy purposes, has an installed power of 4x30MW.
