Hydroelectricity in Turkey
Hydroelectricity is a critical source of energy in Turkey and substantial amounts of it can be generated due to Turkey's mountainous landscape, abundance of rivers, and its position surrounded by three seas. According to the International Hydropower Association Turkey is the world’s ninth largest producer of hydroelectricity in 2020.[citation needed] The main river basins are the Euphrates (Turkish: Fırat) and the Tigris (Turkish: Dicle) rivers. Many dams have been built throughout the country, and a peak of 28GW of power can be generated by hydroelectric plants[1] with 3% of world capacity and almost 90 TWh generated in 2019 around 30% of the country's electricity.[2] Generation varies by year depending on hydrological conditions. There are many policies that support the usage of hydroelectric energy. A number of dams built are subject to controversy as they have had many negative effects on the environment and the wildlife.[3]
History[]
The first hydroelectric plant in Turkey was constructed in Tarsus, Istanbul in 1911 and opened in 1914 as a result of the Balkan Wars. This plant only produced 60 kW, but nonetheless it alone was able to provide power to all of Istanbul for almost 40 years.[4]
Over the years, more and more hydroelectric projects were constructed, such as the Seyhan Dam, the Sarıyar Dam, the Hirfanlı Dam, the Kesikköprü Dam, the Demirköprü Dam, and the Kemer Dam.
After the State Hydraulic Works (DSI) was established in 1954, projects were better funded and the hydroelectric power produced per year greatly increased.[5]
Projects[]
The most recent project in Turkey is the GAP (short for Southeastern Anatolia Project, Turkish: Güneydoğu Anadolu Projesi), the GAP was planned by the DSI, and includes the construction of 22 dams and 19 hydroelectric power plants, the cost of which is 100 billion lira (US$32 billion, 2017 adjusted price). Most of the project has been completed, with some dams and hydroelectric power plants still under construction.[citation needed] Theoretically, 27 billion kWh/year will be generated from the project.[citation needed]
Impacts on people and the environment[]

There have been both positive and negative environmental effects caused by the dams and hydroelectric power plants. One of the positive effects of hydroelectric power plants has been the decrease of carbon emissions, as the production of hydroelectric energy does not emit any byproduct. Compared to thermal energy, hydroelectric energy is much more environmentally friendly because of emissions. Another positive impact has been the decrease of the importation of energy, since Turkey imports around 90% of its energy.[6]
On the other hand, the hydroelectric power plants have had a negative impact on the local fauna. A large amount of fish are killed in hydroelectric power plants because there are no fish passages, which can be improved.[citation needed] Nevertheless, some species have already gone extinct.[citation needed]
Another issue is salinity of the water. The salinity of the water can cause negative effects on water quality, soil erosion, and plant growth. The salinity caused by dams has decreased the agricultural activity near dams and hydroelectric power plants as well.[citation needed] There has also been a great issue with increased bedrock exposure and erosion.[citation needed]
These projects have also caused an issue of land acquisition and resettlement of people. The Atatürk and Karakaya project of the GAP caused the displacement of 100,000 people.[citation needed] Hundreds of villages have been affected by projects in Turkey to build dams and hydroelectric power plants. Some locals were given land as reparations. On the other hand, some people were admitted back to their own properties after the construction of the dams or power plants, if feasible.[7] However, it cannot be denied that there has been disregard to ancient settlements, such of Assyrian, Greek, Armenian, and many more civilizations, such as the destruction of Hasankeyf.[8]
Hydroelectric potential[]
This section needs to be updated. The reason given is: Is potential less now due to less rainfall?.(April 2019) |
Hydroelectric power is one of the most common sources of renewable energy in the world and it plays a vital role in Turkey's energy production as well. The theoretical viable hydroelectric potential of the country has been estimated at 433 TWh/year, nearly 1% of the total hydropower potential of the world,[9] and the hydroelectric technical potential of Turkey is 58 TWh/year, also around 1% of the hydroelectric energy produced in the world.[10] Due to changes in rainfall generation varies considerably from year to year, for example drought in 2020 caused a generation drop of over 10% compared to the previous year.[11]
Energy storage and dispatchability[]
Hydropower usually peaks in April or May.[12] It might be that in coming years the pumped storage power plant market will also grow or start in Turkey[13] as this could store energy produced by wind and solar power plants. Converting existing dams to pumped storage has been suggested as more feasible than new pumped storage.[14] Although dammed hydro can be dispatched within 3 to 5 minutes[15] it has been reported that such generation instructions from Turkish Electricity Transmission Corporation can be countermanded by the State Hydraulic Works and that this was part of the cause of summer blackouts in 2021.[16]
International rivers[]
Dams on international rivers, such as the Ilisu Dam, can cause water shortages in downstream countries.[17]
Statistics[]
This section needs to be updated.(April 2019) |
In 2015, the total installed capacity of hydropower in Turkey was 25868 MW, and total generated energy in 2015 from hydropower was 66903.2 GWh.[9]
Largest stations[]
Name | Power Output in Megawatt |
---|---|
Atatürk Dam | 2400 MW |
Karakaya Dam | 1800 MW |
Keban Dam | 1330 MW |
Ilisu Dam | 1200 MW |
