The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It uses 13 generators at an installed capacity of 2,525 MW (3,386,000 hp) with an average annual net generation of 15,897,000 MWh between 2014 and 2023, and a capacity factor of 71.9%.
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, so 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.
Ambuklao Dam is part of a hydroelectric facility in Baragay Ambuclao, Bokod, Benguet province in the Philippines. With a maximum water storage capacity of 327,170,000 cubic metres (265,240 acre⋅ft), the facility, which is located 36 km (22 mi) from Baguio, can produce up to 105 megawatts of electricity for the Luzon grid. The main source of water is the Agno River, which originates from Mount Data. The dam is located in a conservation area known as the Upper Agno River Basin Resource Reserve.
The Pulangi River ;, also spelled Pulangui, is one of the major tributaries of the Rio Grande de Mindanao, an extensive river system in Mindanao, Philippines. With a length of 320 kilometres (199 mi), it is the longest river in Bukidnon and the 5th longest river in the Philippines. It traverses through majority of the cities and municipalities of Bukidnon from its source in Barangay Kalabugao, Impasugong, Bukidnon.
Magat Dam is a large rock-fill dam in the island of Luzon in the Philippines. The dam is located along the Magat River, a major tributary of the Cagayan River. The construction of the dam started in 1975 and was completed in 1982. It is one of the largest dams in the Philippines. It is a multi-purpose dam which is used primarily for irrigating about 85,000 hectares of agricultural lands, flood control, and power generation through the Magat Hydroelectric Power Plant.
Ōhashi Dam (大橋ダム) is a dam built on the Yoshino River in Agawa District, Kōchi Prefecture of Japan. This concrete dam 73.5 m high. It is a hydroelectric dam of the Shikoku Electric Power Company. It supplies water to the company's hydroelectric plant, Ōhashi Power Station, which can produce up to 5,500 kW. It is the lower reservoir for a pumped-storage hydroelectric plant. The upper reservoir being Inamura Dam. Water flowing between these two can produce up to 615MW. It is a public works which The Japan Society of Civil Engineers has recommended as a site of Public Works Heritage.
The Kölnbrein Dam is an arch dam in the Hohe Tauern range within Carinthia, Austria. It was constructed between 1971 and 1979 and at 200 metres (660 ft) high, it is the tallest dam in Austria. The dam's reservoir serves as the primary storage in a three-stage pumped-storage power system that consists of nine dams, four hydroelectric power plants and a series of pipeline and penstocks. The complex is owned by Verbund power company and is referred to as the Malta-Reisseck Power Plant Group. The installed capacity of the group is 1,028.5 MW and its annual generation is 1,216 gigawatt-hours (4,380 TJ).
Lumot River Dam is an embankment dam located between the towns of Cavinti and Lumban, in the province of Laguna, Philippines. The dam was constructed across Lumot River creating a reservoir now known as Lumot Lake or Sierra Lake. Lumot Lake provides additional water through a Bell-mouth spillway and tunnel to Caliraya Lake, which in turn serves as the upper reservoir for the Kalayaan Pumped-Storage Hydroelectric Plant.
Lumot Lake, also known as Sierra Lake, is a man-made water reservoir located in the towns of Cavinti and Lumban of Laguna province, in the Sierra Madre Mountains of the Philippines. The lake was created when Lumot Dam, an embankment dam, was constructed damming the Lumot River, creating an auxiliary water reservoir for Lake Caliraya as part of the Kalayaan Pumped-Storage Hydroelectric Plant. The waters between the two lakes are conveyed by a 2.3 kilometres (1.4 mi) penstock.
The Shin-Takasegawa Pumped Storage Station (新高瀬川発電所) uses the Takase River to operate a pumped storage hydroelectric scheme about 12 kilometres (7.5 mi) west of Ōmachi in Nagano Prefecture, Japan. Part of the system is within Chūbu-Sangaku National Park.
The Salina Pumped Storage Project is a 260-megawatt (350,000 hp) pumped-storage power station near Salina, Oklahoma. It is owned and operated by the Grand River Dam Authority (GRDA). Its construction was in response to growing power demands and a lack of dam sites on the Grand River. The first phase was completed in 1968 and the second in 1971. The upper reservoir for the power station is Lake W. R. Holway which was built on Saline Creek and the lower reservoir is Lake Hudson on the Grand River. During periods of lower power demand, water is pumped from Lake Hudson to Lake Holway and released back down through the pump-generators during periods of high energy demand.
The Pulangi IV Hydroelectric Power Plant, also known as the Pulangi Dam, is located on the Pulangi River near Maramag in Bukidnon province on the island of Mindanao in the Philippines. It uses two reservoirs, produced by damming the Pulangi River, to supply water to a run-of-the-river hydroelectric power plant; the power plant is capable of generating 255 megawatts (342,000 hp) of power. Construction began in 1982; the first two generators became operational in December 1985, with the last generator being commissioned in 1986.
The Helms Pumped Storage Plant is located 50 mi (80 km) east of Fresno, California in the Sierra Nevada Mountain Range's Sierra National Forest. It is a power station that uses Helms Creek canyon on the North Fork of the Kings River for off-river water storage and the pumped-storage hydroelectric method to generate electricity. After being planned in the early 1970s, construction on the plant began in June 1977 and commercial operations began on 30 June 1984. It has an installed capacity of 1,212 MW and is owned by Pacific Gas and Electric Company.
The Edolo Pumped Storage Plant is located along the Oglio River just downstream of Edolo, Brescia Province in the Lombardy region of Italy. Using the pumped-storage hydroelectric method, it has an installed capacity of 1,000 megawatts (1,300,000 hp). Its generators were commissioned between April 1984 and November 1985. Lake Avio was previously completed in 1929 and Lake Benedetto completed in 1940.
The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River system, in the Sierra Nevada of central California. The project is owned and operated by Southern California Edison (SCE). The use and reuse of the waters of the San Joaquin River, its South Fork, and the namesake of the project, Big Creek – over a vertical drop of 6,200 ft (1,900 m) – have over the years inspired a nickname, "The Hardest Working Water in the World".
The Yuba–Bear Hydroelectric Project is a complex hydroelectric scheme in the northern Sierra Nevada in California, tapping the upper Yuba River and Bear River drainage basins. The project area encompasses approximately 400 square miles (1,000 km2) in Nevada, Placer, and Sierra Counties. Owned by the Nevada Irrigation District, it consists of 16 storage dams plus numerous diversion and regulating dams, and four generating stations producing 425 million kilowatt hours of electricity each year. The Yuba–Bear Hydroelectric Project consists of the Bowman development, Dutch Flat No. 2 development, Chicago Park development, and Rollins development.
Seattle Municipal Light and Power Plant, also known as Cedar Falls Historic District, is a public hydroelectric plant near North Bend, Washington operated by Seattle City Light.
