Summary

Manavgat Regulator and HES project whose construction has not started yet, uses the energy potential between the 815.00 – 710.00 m of Manavgat creek.

The project consists of regulator structures, a long penstock and a powerhouse that contains two big and one small  Francis turbines.

One of the project’s main structures is 1500 m long penstock. It is been proved to be more convenient for the project in terms of its feasibility and affordability to have a pipeline that will be based next to the stream bed, embedded to the ground, designed as a pressurised GRP pipe instead of a conventional unpressurised pipeline. By this way, the expropriation price of the project is reduced as well as the negative social and environmental effects. In order to keep the pressure levels in the GRP pipe line at a reasonable level, pressure reducer valves (PRV) will be constructed in the powerhouse. Energy production in low capacities will be able to generated in the powerhouse, which contains two big and one small horizontal Francis turbines.

Summary

Tüfekcikonagi Hydropower Project is located in Marmara Region within the border of Inegol district of Bursa province over the creek of Sacmali. Karaburun, Biçki, Uçuncu and Bogakaya Weirs along the branches of this river, divert water to Tüfekçikonagi HEPP using the head between elevations 962.50 m and 615 m of Saçmalı Creek.

The surroundings of the construction site are very steep and covered by extensive vegetation. This facility, which consists of relatively small hydraulic structures in order to be in compliance with the topography, has a significant production capacity due to the high head it makes use of. The water collected by different branches of the Saçmali Creek by four above mentioned weirs is conveyed to forebay through GRP pipes - 0.50 m and 0.80 m in diameter and 2 680 m in length - and U-PVC pipes- 0.90 m and 1.20 m in diameter and 2 040 m in length. The water transmission line placed under or near the existing roads as much as possible to minimize the negative environmental effects. Due to the fact that it is not practical to store water in the four weirs separately, a forebay as large as the topography allows is designed with a reservoir possessing 16 800 m3 daily storage capacity, thereby making it possible to increase the energy output at peak hours with the help of two Pelton type turbines.

Summary

Aksar Weir and Nazar Hydropower Project are located in Eastern Anatolia Region within the border of Hizan district of Bitlis province over the creek of Sutopu. Aksar Weir has a catchment areaof 1,000.10 km2 along this river and diverts water to Nazar HEPP.

According to the feasibility report that was prepared in 2005, Akşar Weir and Nazar HEPP was composed of two diversion weirs, a conveyance channel having a length of 10.5 km, forebay, penstock and power house.It was determined that construction of the conveyance channel above the ground is inappropriate in terms of economical and environmental aspects considering field observations and office studies that were conducted by Prosem Engineering. Revised feasibility report was prepared by modifying the formulation which minimizes the cost of expropriation as well as negative social and environmental impacts. The new formulation composes of a single weir which has daily reservoir and pressurized tunnel together with surge chamber. The tunnel which has an inner radius of 4.00 m with modified horse-shoe cross-section and a length of 7,500 m is designed as coated due to geological and hydraulic reasons. The thickness of concrete cover and the amount of reinforcement have been determined considering the hydrostatic pressures over the tunnel. Steel coating has been used at the regions where the hydrostatic pressure was not carried by rock mass over the tunnel and at the regions between the surge chamber shaft and the powerhouse. In order to keep the pressure rises at reasonable levels, surge chamber, having an upper tank with a radius of 15 m and a height of 21 m, was designed at the closest location to the power house considering the suitability of the location in terms of geological and topographical aspects. As a result of all the modifications, a storage of 150 000 m³ has been obtained and the energy production has been shifted to peak hours. Two Francis turbines of equal capacity have been erected in powerhouse. Another turbine having 300 kW capacity has been constructed within the weir in order to take the advantage of the energy of the first water flowing into the creek.

Summary

Angutlu I - II Hydropower Projects are cascade hydropower schemes which are located in Black Sea Region within the border of Dereli district of Giresun province over the creek of Aksu. Angutlu–I weir has a catchment area of 722 km2 along this river and diverts water to Angutlu–I HEPP whereas Angutlu–II weir with a catchment area of 782.00 km2 diverts water to Angutlu–II HEPP.

Both projects have a similar formulation in that in both projects the flows taken by water intake structures are conveyed through power tunnels to the power plants that contain two big and a small Francis type turbine. Angutlu-II weir which is located at the downstream of Angutlu-I HEPP and near the city center of Dereli is designed for Q500 flood discharge of 680.94 m3/s by installing five units of 8.0 m width flap gates on the spillway.

In Angutlu I - II Hydropower Projects w rhich are located in close vicinity of the city center where bulding stock has a considerable density, the conveyance lines are planned as pressurized tunnels taking the probable expropriation costs into consideration. Since the flows are transmitted directly to the powerhouse via energy tunnels, there was no more need for constructing a forebay and penstock. Besides, to reduce waterhammer effect “Pressure Relief Valves (PRV)” which ensure savings both from cost and space are installed in the powerhouse instead of building a surge tank. In this manner, the negative environmental effects and construction and expropriation costs are reduced to the least possible extent thereby ensuring the smooth and rapid construction of the project facilities. The transient analysis related with the waterhammer effect and adaptation of the PRVs to the system are also carried out by Prosem Engineering.

Summary

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.

The construction of the project started in September 2010 and the project is in operation since 2012. Kizkayasi Dam and HEPP are going to be constructed at the upstream of Devecikonagi Dam and HEPP project.

RCC Dam

Due to the facts that the body of the dam is RCC (Roller Compacted Concrete) and 40 m high from foundation. The spillway is designed for Q500 flood discharge which is 2,545 m3/s. In order to maximize the energy generation, the highest possible head is achieved by keeping the operating water level same as flood level with a five radial gate-controlled-spillway. Dam reservoir is 660.000 sq.m in area and 6.2 M cu.m in volume at the operating water level, 95 m. The dam has an active storage of 1.9 M cu.m to carry out the daily regulation. The crest length of the body constructed within the scope of the project is 298 m including spillway and the total RCC volume is about 60.000 cu.m.

Semi Indoor Powerhouse

The semi indoor powerhouse located on the toe of the dam contains three Kaplan type turbines; two of them have equal hydraulic capacities of 57.5 m3/s and the other one has 5 m3/s.

Energy from Irrigation Water

Low capacity turbine was designed to supply water needed for Dolluk-Gulluce Irrigation Project constructed by the State Hydraulic Works as well as to generate energy using this water.

Riverbed Excavation

At the tailrace of Devecikonagi Dam, a riverbed excavation is carried out up to 7 m depth to reduce the downstream water level, thereby reducing the amount of inundated agricultural lands which in turn reduces the negative social effects as well as expropriation cost and increases the amount of energy production.

Summary

Kayraktepe Dam & HEPP Project is located at Silifke district of İçel province over Göksu River. Although Kayraktepe Dam & HEPP project remains on the agenda for over 30 years, the construction has never been realized due to several reasons. The most important difficulty is the huge reservoir behind dam body that would cause negative social and environmental impacts as well as high expropriation costs, which necessitates the modification of the project formulation. Kayraktepe Dam is a multi-purpose project of energy irrigation and flood protection. These purposes are carried out by the modified project. In the reformulation; instead of a single large dam, five run of the river type hydroelectric power projects and one middle size dam has been considered. However, reducing the reservoir volume of the project also reduces the efficiency of the dam in flood control. In order to examine the efficiency of the whole project at flood control, Prosem Engineering has performed a detailed basin planning for Goksu River.

Göksu River and Ermenek Creek confluence at the upstream of Kayraktepe Dam, therefore, the effects of Ermenek Dam and Gezende Dam located over Ermenek Creek and Mut Dam planned to be constructed over Göksu River are included in the calculations for basin planning. In the study, the basins of each dam are determined and the flood hydrographs for those as well as for sub basins are estimated. Then, flood routing studies of these dams are carried out and the inflow hydrographs of Kayraktepe Dam are generated. Following, flood routing of Kayraktepe Dam is conducted and the outflow hydrographs of the dam are produced. Using these flow data, water surface elevations in Silifke Plain and Silifke District have been calculated and probable inundated lands have been determined. Consequently, it has been seen by extensive studies that the reformulated design is adequate for flood protection. By using these studies Adana Regional Directorate of State Hydraulic Works published “Kayraktepe Barajı Revize Hidroloji Çalışmaları Raporu” in 2011.
