Run-of-the-river Hydroelectric
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. Concept Run-of-the-river, or ROR, hydroelectricity is considered ideal for streams or rivers that can sustain a minimum flow or those regulated by a lake or reservoir upstream. A small dam is usually built to create a headpond ensuring that there is enough water entering the penstock pipes that lead to the turbines, which are at a lower elevation. Projects with pondage, as opposed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chief Joseph Dam
The Chief Joseph Dam is a concrete gravity dam on the Columbia River, upriver from Bridgeport, Washington. The dam is upriver from the mouth of the Columbia at Astoria, Oregon. It is operated by the USACE Chief Joseph Dam Project Office and the electricity is marketed by the Bonneville Power Administration. History The dam was authorized as Foster Creek Dam and Powerhouse for power generation and irrigation by the ''River and Harbor Act of 1946''. The ''River and Harbor Act of 1948'' renamed the project Chief Joseph Dam in honor of the Nez Perce chief who spent his last years in exile on the Colville Indian Reservation. Because of its lack of fish ladders, Chief Joseph Dam completely blocks salmon migration to the upper Columbia River system. Construction began in 1950, with the main dam and intake structure completed in 1955. Installation of the initial generating units was started in 1958 and completed in 1961. Ten additional turbines were installed between 1973 and 1979, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
