Wells Dam is a hydroelectric embankment dam located on the Columbia River, downstream from the confluence of the Okanogan River, Methow River, and the Columbia River in Washington state. The dam, associated structures, and machinery make up the Wells Hydroelectric Project. It is owned and operated by Douglas County Public Utility District.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power.
The Balimela Reservoir is located in Malkangiri district, Odisha, India on the river Sileru which is a tributary of the Godavari river. The gross storage capacity of Balimela reservoir is 3610 million cubic meters.
The Conowingo Dam is a large hydroelectric dam in the lower Susquehanna River near the town of Conowingo, Maryland. The medium-height, masonry gravity dam is one of the largest non-federal hydroelectric dams in the U.S., and the largest dam in the state of Maryland.
High Rock Lake is a reservoir located on the Yadkin River in central North Carolina in the counties of Davidson and Rowan. Built in 1926-27 by the Tallassee Power Company, a wholly owned subsidiary of the Aluminum Company of America (Alcoa), the lake is the northernmost of a series of four hydroelectric projects designed at the time to support the company’s Badin Works, a large aluminum smelting operation located 16 miles downstream in the community of Badin. After the permanent closing of the Badin Works in 2007, Alcoa continued to operate its Yadkin hydroelectric facilities until selling them to Cube Hydro Carolinas in 2016.
Holtwood Dam is the oldest of three major dams built across the lower Susquehanna River, and the middle location of the three. It was constructed as the McCalls Ferry Dam between 1905 and 1910 by the Pennsylvania Water & Power (PW&P) Company. The dam was renamed Holtwood in honor of two company executives. PW&P merged with Pennsylvania Power & Light (PPL) in 1955. In 2015 Talen Energy took over PPL's generation and immediately sold the Holtwood plant to Brookfield Renewable Energy Partners to comply with federal antitrust requirements.
Susquehanna State Park is a Pennsylvania state park on 20 acres (8.1 ha) in Williamsport in Lycoming County, Pennsylvania in the United States. The park is on the West Branch Susquehanna River in the western part of Williamsport, and is operated by the Williamsport / Lycoming Chamber of Commerce in cooperation with the Bureau of State Parks of the Pennsylvania Department of Conservation and Natural Resources. Susquehanna State Park offers cruises on a paddlewheeler, boating, fishing, and picnicking.
York Haven Dam is a low head, run-of-the river, dam and hydroelectric plant on the Susquehanna River, United States. The dam is 12 miles (19 km) south of Harrisburg, Pennsylvania, at the Conewago Falls impounding about 8,000 feet (2,400 m) of the river to the west side of Three Mile Island, where the river drops 19 feet (5.8 m) in 1⁄4 mile (0.40 km). When the dam was completed in 1904, it was the third largest in the world.
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture.
This article details a history of Lycoming County, Pennsylvania.
The Assiut Barrage is a dam on the Nile River in the city of Assiut in Upper Egypt. It was completed in 1903.
Low-head hydropower refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge. Using only a low head drop in a river or tidal flows to create electricity may provide a renewable energy source that will have a minimal impact on the environment. Since the generated power is a function of the head these systems are typically classed as small-scale hydropower, which have an installed capacity of less than 5MW.
Richard B. Russell Dam is a concrete-gravity and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Richard B. Russell Lake. The dam was built by the U.S. Army Corps of Engineers between 1974 and 1985 for the purposes of flood control, hydroelectricity, recreation, additional stream flow regulation, water supply, and fish and wildlife management. The concrete structure of the dam spans 1,904 feet (580 m) and rises 210 feet (64 m) above the riverbed, housing a hydro-power plant with an installed 600 megawatts (800,000 hp) capacity. The Richard B. Russell Dam is the final large dam completed by the U.S. Army Corps in the Savannah River Basin and lies 30 miles downstream from the Hartwell Dam (1962) and 37 miles (60 km) upstream from the J. Strom Thurmond Dam (1954).
The Sambor Dam is a proposed dam and hydroelectric power station on the Mekong River south of Sambor village in Prek Kampi District, Kratie Province, Cambodia. If built, it would be the lowest dam of the Mekong's mainstream dams, and largest in Cambodia.
Hydroelectricity is a major source of electricity in Turkey, due to its mountainous landscape and many rivers. The country's main river basins are those of the Euphrates and the Tigris. Over 700 hydropower plants have been built, and hydroelectricity makes up about 30% of the country's electricity generating capacity. Generation can vary greatly from one year to the next, depending on rainfall. In good years, substantial amounts of hydroelectric power can be generated. Government policies have generally supported dam construction, but some dams are controversial in neighbouring countries, while others raise concerns about damage to the environment and wildlife of Turkey.
Patrind Hydropower Plant is a run-of-the-river, high head project of 110 metres (360 ft), located on Kunhar River near Patrind Village right on the border of Abbottabad District of Khyber Pakhtunkhwa Province and Muzaffarabad city of Azad Kashmir, Pakistan. It is approximately 138 kilometres (86 mi) from Rawalpindi and Islamabad and about 76 kilometres (47 mi) from Abbottabad city.
Moore Dam is a major hydroelectric dam on the Upper Connecticut River between Grafton County, New Hampshire and Caledonia County, Vermont in the northeastern United States. The dam is located near Littleton, New Hampshire, and forms the 3,490-acre (1,410 ha) Moore Reservoir. The Moore Station is the largest conventional hydroelectric plant in New England, in terms of installed capacity and average power generation. The dam and reservoir also provide flood control, recreational boating and fishing.
The Moragolla Dam is a planned hydroelectric dam in Moragolla, Sri Lanka. The dam is to be 35 m (115 ft) high and is planned to create the 1,980,000 m3 (70,000,000 cu ft) Moragolla Reservoir with a maximum supply level at 548 m (1,798 ft) MSL. Upon completion, the Moragolla Power Station would have a gross installed capacity of 30 megawatts from two francis turbines, capable of generating approximately 85 GWh annually.
Karura Hydroelectric Power Station, commonly referred to as Karura Power Station, also Karura Dam, is a planned 90 MW hydropower station in Kenya.
