Hydroelectricity is electricity produced from hydropower. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was expected to increase about 3.1% each year for the next 25 years.
Batman Dam is one of the 22 dams of the Southeastern Anatolia Project of Turkey, built on the Batman River, north of Batman, in southeastern of Turkey. It was constructed between 1986 and 1999. There is a hydroelectric power plant, established in 1998, at the dam, with a power output of 191.7 MW. The dam is designed to service an irrigation area of 37,744 ha. The Silvan Dam is located upstream.
Dicle Dam is one of the 21 dams of the Southeastern Anatolia Project of Turkey. These facilities are located within the provincial territory of Diyarbakır, at a distance of 50 kilometres to Diyarbakır city centre. More specifically, the dam and the hydroelectric power plant are located at a distance of 800 metres from the point of junction of the streams of Maden Stream and Dibni to form the Tigris, and 22 kilometres downstream of the Kralkızı Dam. Construction works were started in 1986 and the dam was completed in 1997. The dam has an installed hydroelectric capacity of 110 MW and is designed to ultimately irrigate 128,080 hectares. In 2001 a water transmission line and a water treatment plant were commissioned that provided about 85% of the drinking water for the city of Diyarbakir in 2010.
The Ilısu Dam is a concrete-face rock-fill dam on the Tigris near the village of Ilısu and along the border of Mardin and Şırnak Provinces in Turkey. It is one of the 22 dams of the Southeastern Anatolia Project and its purpose is hydroelectric power production, flood control and water storage. When operational, the dam will support a 1,200 MW power station and will form a 10.4 billion m3 reservoir. Construction of the dam began in 2006 and was originally expected to be completed by 2016. As part of the project, the much smaller Cizre Dam is to be constructed downstream for irrigation and power. The dam has drawn international controversy, because it will flood portions of ancient Hasankeyf and necessitate the relocation of people living in the region. Because of this, the dam lost international funding in 2008. Kurdish Kurdistan Workers' Party militants have also attacked infrastructure associated with the dam which led to construction delays.
Longtan Dam is a large roller-compacted concrete (RCC) gravity dam on the Hongshui River in Tian'e County of the Guangxi Zhuang Autonomous Region, China, a tributary of the Xi River and the Pearl River. The dam is 216.2 metres (709.3 ft) high and 849 m (2,785 ft) long; it is the tallest of its type in the world. The dam is intended for hydroelectric power production, flood control and navigation. The dam contains seven surface spillways, two bottom outlets and an underground power station. The Longtan ship lift, part of the dam complex, will be the tallest ship lift system in the world.
The 2009 Ecuador electricity crisis was caused by a severe drought that depleted water levels at hydroelectric plants. Ecuador experienced rolling blackouts for two to six hours per day that lasted from November 2009 until January 2010.
The Torul Dam is a concrete-face rock-fill dam on the Harşit River located 10 km (6 mi) northwest of Torul in Gümüşhane Province, Turkey. The development was backed by the Turkish State Hydraulic Works. Construction on the dam began in 1998 and was completed in 2007. The dam's hydroelectric power plant was commissioned in 2008. Water is diverted through a tunnel and penstock on the river's north side where it reaches the power plant located about 4 km (2 mi) downstream. It has an installed capacity of 121.5 MW.
The Longyangxia Dam is a concrete arch-gravity dam at the entrance of the Longyangxia canyon on the Yellow River in Gonghe County, Qinghai Province, China. The dam is 178 metres (584 ft) tall and was built for the purposes of hydroelectric power generation, irrigation, ice control and flood control. The dam supports a 1,280 MW power station with 4 x 320 MW generators that can operate at a maximum capacity of 1400 MW. Controlling ice, the dam controls downstream releases to reservoirs lower in the river, allowing them to generate more power instead of mitigating ice. Water in the dam's 24.7 billion m3 reservoir provides irrigation water for up to 1,000,000 hectares of land.
The Kirazlık Dam is a gravity dam on the Botan River, 9 km (6 mi) east of Siirt in Siirt Province of southeastern Turkey. The purpose of the dam is to regulate the outflow of the Alkumru Dam upstream and to produce hydroelectric power with a run-of-the-river design. The dam was completed in late 2011 and the power station become operational in 2013. The power plant houses three 15 MW Kaplan turbine-generators.
The Artvin Dam an arch-gravity dam on the Çoruh River in Artvin Province, Turkey. Preliminary construction on the dam began in December 2010 and the river diversion tunnels were complete in July 2012 at which time construction on the dam foundation started. The purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 340 MW when completed. The dam is part of the Çoruh Development Plan and its construction was supervised by Turkey's State Hydraulic Works. The dam began to impound its reservoir in October 2015 and the power station was commissioned beginning in January 2016.
The Arkun Dam an embankment dam on the Çoruh River near İspir in Erzurum Province, Turkey. Construction began in 2011 and the primary purpose of the dam is hydroelectric power generation. It is part of the Çoruh Development Plan and its construction is being supervised by Turkey's State Hydraulic Works. The dam and power plant were completed early, in June 2014. Water from the dam's reservoir supplies two power stations; one at the dam's toe (base) and the other downstream in Artvin Province.
The Güllübağ Dam is a gravity dam near the town of Güllübağ on the Çoruh River in Erzurum Province, Turkey. The primary purpose of the dam is hydroelectric power production.
