The Isar is a river in Austria and in Bavaria, Germany. Its source is in the Karwendel mountain range of the Alps. The Isar river enters Germany near Mittenwald and flows through Bad Tölz, Munich, and Landshut before reaching the Danube near Deggendorf. With 295 km length, it is among the longest rivers in Bavaria. It is Germany's second most important tributary of the Danube.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4,500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
The Sacramento Municipal Utility District (SMUD) is a community-owned electric utility serving Sacramento County and parts of Placer County. It is one of the ten largest publicly owned utilities in the United States, generating the bulk of its power through natural gas and large hydroelectric generation plants. SMUD's green power (renewable) energy output was estimated as 33.8% in 2020.
GandhisagarDam is situated at a distance of 168 km from the District headquarter. The Dam is constructed on the Chambal River.
Lake Qaraoun is an artificial lake or reservoir located in the southern region of the Beqaa Valley, Lebanon. It was created near Qaraoun village in 1959 by building a 61 m-high (200 ft) concrete-faced rockfill dam in the middle reaches of the Litani River. The reservoir has been used for hydropower generation, domestic water supply, and for irrigation of 27,500 ha.
The Reno is a river of Emilia-Romagna, northern Italy. It is the tenth longest river in Italy and the most important of the region apart from the Po.
Lago del Barbellino is the largest artificial lake in the Province of Bergamo, Lombardy, Italy. It is located in Valbondione among the Bergamasque Alps. The reservoir contains 18.5 million cubic metres of water. In 1931 a dam was built to supply hydroelectric power to the Seriana Valley where the textile industry was rapidly developing.
The El Cajón Dam, officially known as Central Hidroeléctrica Francisco Morazán, is a hydroelectric power plant located in Western Honduras. The dam impounds the Comayagua River, which derives its large volume from two large tributaries, the Humuya River and the Sulaco River. El Cajón is a double arch dam, which uses parabolic geometry in horizontal and vertical axises to spread the weight of the impounded water to canyon walls which act as buttresses. Overall, the dam is the fifth highest dam in the Americas and the 15 th highest in the world, as well as the highest arch dam in the western hemisphere, and the sixth highest worldwide.
The Shamkir reservoir is a large reservoir in the Shamkir Rayon of northwestern Azerbaijan. It is the second largest reservoir in the Caucasus after the Mingachevir reservoir.
Techi Dam is a concrete thin arch dam on the Dajia River in Heping District, Taichung, Taiwan. Forming the 454 ha (1,120-acre) Techi Reservoir (德基水庫), the dam is built in the Tachien Gorge in Heping District, providing hydroelectric power, irrigation water, and some flood control, and is operated by the Taiwan Power Company. At 180 m (590 ft), it is the highest dam in Taiwan and one of the tallest dams in the world. The dam was completed in 1974 after five years of construction.
The Daecheong Dam is a combination concrete gravity and embankment dam on the Geum River, 16 km (10 mi) north of Daejeon in South Korea. The multi-purpose dam provides benefits of flood control, water supply and hydroelectric power generation. Construction on the dam began in 1975 and was formally commissioned on 1 December 1980. The 72 m (236 ft) high rock-fill dam has a central clay core and has created a reservoir with storage of 1,490,000,000 m3 (1,207,963 acre⋅ft).
The Kishanganga Hydroelectric Project is a run-of-the-river hydroelectric scheme in Jammu and Kashmir, India. Its dam diverts water from the Kishanganga River to a power plant in the Jhelum River basin. It is located near Dharmahama Village, 5 km (3 mi) north of Bandipore in the Kashmir valley and has an installed capacity of 330 MW.
The Daryan Dam, also spelled Darian, is an embankment dam constructed on the Sirvan River just north of Daryan in Paveh County, Kermanshah Province, Iran. The primary purpose of the dam is to supply up to 1,378,000,000 m3 (1,117,000 acre⋅ft) of water annually to the 48 km (30 mi) long Nowsud Water Conveyance Tunnel where it will irrigate areas of Southwestern Iran. The dam also has a 210 MW hydroelectric power station. Construction on the dam began in 2009 and the dam began to fill its reservoir in late November 2015. The Darian Dam Archaeological Salvage Program (DDASP) was planned by Iranian Center for Archaeological Research before flooding the reservoir. As a result, a number of important archaeological sites were discovered and some were excavated. The power station was commissioned in 2018. The dam's diversion tunnel was completed in June 2011. The dam was designed by Stucky of France and consultation was provided by Mahab Ghodss, International Consulting Engineering Co. In August 2010 Farab Co. won the contract to build the power station. In 2011, workers on the project held a protest against unpaid wages. The dam is also the subject of protest due to the forced relocations and ecological/cultural impact its reservoir will have.
The Upper North Fork Feather River Project is a hydroelectric scheme in the Sierra Nevada of California, within Lassen and Plumas Counties. The project consists of three dams, five power plants, and multiple conduits and tunnels in the headwaters of the North Fork Feather River, a major tributary of the Feather—Sacramento River systems. The total installed capacity is 362.3 megawatts (MW), producing an annual average of 1,171.9 gigawatt hours (GWh). The project is also contracted for the delivery of irrigation water between March 31 and October 31 of each year. The project is owned and operated by Pacific Gas and Electric Company.
Veluthodu dam is a part of Kakkad Hydro Electric Project and is located in Seethathode panchayath of Ranni Taluk in Pathanamthitta District of Kerala, India. Its a Concrete-Gravity dam built across the Veluthodu river, a tributary of Kakkad River which is again a tributary of Pamba River The dam is built primarily for electricity. This diversion dam diverts water to the water conductor system from Moozhiyar reservoir to Kakkad Power Station. This power station utilises the tail race water from Sabarigiri power station and flow received from moozhiyar and velluthode rivers. After power generation, water from Kakkad power station is released to the Kakkad River. Taluks through which release flow are Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally It is operated by Kerala State Electricity Board.
