Demand for energy is constantly growing both in the world and in Turkey. Sustainable development being an important concept, development of small hydro power projects has been popular in recent years. Eastern Black Sea Basin in Turkey has a lot of small hydro power potential because of high amount of precipitation and existence of steep slopes. Since the amount of river runoff is the only parameter that is variable in order to determine the power potential, it is vital to estimate the project discharge in ungauged basins accurately that have hydro power potential. Projects discharges of hydro-power plants in ungauged basins have been calculated using conventional methods up to now. This study aims to introduce a statistical model in linear and multi-variate form using the topographical and morphological parameters derived from GIS and hydro-meteorological variables to estimate the specific flow duration curves of potential small hydro-power locations for the selected study areas in Eastern Black Sea Region namely Solaklı and Karadere basins. As well as developing an annual regression model using the annual values of hydro-meteorological parameters; seasonal regression model (spring season) has also been developed by including the mean seasonal (spring) air temperature variable instead of snow covered area (SCA) in addition to basin parameters. By studying the spring model, effect of different variables from the annual model were tested and discussed with some recommendations for the future studies.

Hydropower is the most important domestic energy source of Turkey. Thus, wise planning and development of the unused hydropower potential of the country is vital. There are many hydroelectric power plants under planning stage in our country. Altıparmak HEPP is one of them. General Directorate of Electrical Power Resources Survey and Development Administration (EİE) and ANC Enerji conducted two separate feasibility studies for Altıparmak HEPP in 2001 and 2009, respectively. Traditionally, the energy income c...

Energy requirement of Turkey increases day by day and hydropower is currently the main renewable energy source of the country. Thus, planning the development of the unused hydropower potential of Turkey is critical. Available water resources have to be developed and managed in a wise manner. Reservoir operation rule curves are fundamental guidelines for long term reservoir operation. Rule curve which results in the maximum energy generation has to be developed for each hydropower plant (HEPP). The goal of t...
Renewable energy planning in Turkey with a focus on hydropower
Gök, Emre; Kentel Erdoğan, Elçin; Department of Civil Engineering (2013)
As a country highly dependent on foreign fossil fuel sources, Turkey experiences many problems due to its increasing energy consumption in parallel with increasing population and rapid economic growth. Foreign fossil fuel dependency adversely affects sustainable development of the country by hindering its economic development. Because of this, renewable energy sources of the country should be evaluated and developed as soon as possible. Prioritization of the development of renewable energy sources to increa...
Balkusan Dam and HEPP : investigation of better alternatives to EİEİ formulation
Çetinkaya, Mehmet Akın; Kentel Erdoğan, Elçin; Department of Civil Engineering (2013)
Due to the economic and social growth of Turkey, there is a rapid increase in energy demand. Turkey does not have sufficient natural gas and petroleum reserves; however, it has large hydropower potential. Hydropower is the most widely used form of renewable energy. To generate electricity between elevations 1500 m and 450 m on Balkusan Creek, General Directorate of Electrical Power Resources Survey and Development Administration (EIEI) conducted a feasibility study for a hydroelectric power plant (HEPP) com...

As a fast growing country, Turkey’s energy demand has been increasing every year and new investments are needed in the renewable energy sector. Turkish government uses the Build-Operate-Transfer (BOT) model to realize urgent investments in the hydroelectric energy sector. Given the government’s purchase guarantee of the generated electricity, hydroelectric power plant (HEPP) projects can be feasible options for investors. However, during the feasibility studies, risk factors stemming from the macro environm...
