Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
The houses were removed in the 1960s when the dam was retrofitted to allow remote operation of the generating equipment from Rochester. The impoundment created is called Lake Zumbro. This dam spans 904 feet (276 m) and is 66 feet (20 m) high, creating a reservoir with about 55 feet (17 m) of hydraulic head. [2]
Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2] 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 ...
Previous upstream dams and reservoirs were part of the 1980s James Bay Project. There are also small and somewhat-mobile forms of a run-of-the-river power plants. One example is the so-called electricity buoy, a small floating hydroelectric power plant. Like most buoys, it is anchored to the ground, in this case in a river.
The head of the Ukrainian state-owned energy company Ukrhydroenergo, Ihor Syrota , said that the Hydroelectric Power Station-2 (HPS-2), one of the dam's two power stations, was in critical condition after being struck directly by two missiles, damaging crane girders and a support pillar. A trolleybus travelling along the dam's roadway was also ...
Inside the Robert-Bourassa generating station, in northern Quebec, the world's largest underground power station, with an installed capacity of 5,616 MW.. An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods.
A photo showing an older flashboard system of the Holyoke Dam and the Canal System's original gatehouse. The river between Holyoke and South Hadley contained what was known as the "Great Falls" a natural 53-foot (16 m) drop in the river approximately 86 miles upstream of the Atlantic Ocean.
The Yacyretá Dam or Jasyretâ-Apipé Hydroelectric Power Station (from Guaraní jasy retã, "land of the moon") is a dam and hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé in the Paraná River, between the Paraguayan City of Ayolas and the Argentine Province of Corrientes.
