Castaic Power Plant Front
Castaic () ( Chumash: ''Kaštiq''; Spanish: ''Castéc'') is an unincorporated community in the northwestern part of Los Angeles County, California. As of the 2010 census it had a population of 19,015. For statistical purposes the Census Bureau has defined Castaic as a census-designated place (CDP). Tens of thousands of motorists pass through Castaic daily as they drive to or from Los Angeles on Interstate 5 (the Golden State Freeway). Castaic Lake is part of the California Water Project and is the site of a hydro-electric power plant. Castaic is northwest of Los Angeles Union Station and northwest of the city of Santa Clarita. The Castaic Range War went on for decades in the late 19th and early 20th centuries resulting in dozens of deaths before hostilities ceased in 1916. Name The name is derived from the Chumash word ''Kaštiq'', meaning "the eye".John R. Johnson, "The Trail to Kashtiq," ''The Journal of California Anthropology,'' vol 5, no 2, pp 188–198SCVHistor ...

Castaic Power Plant
Castaic Power Plant, also known as the Castaic Pumped-Storage Plant, is a seven unit pumped-storage hydroelectric plant, operated by the Los Angeles Department of Water and Power, which provides peak load power from the falling water on the West Branch of the California State Aqueduct. It is a cooperative venture between the LADWP and the Department of Water Resources of the State of California. An agreement between the two organizations was signed on September 2, 1966, for construction of the project. Location The Castaic Power Plant is located about from the northern Los Angeles city limits at the upper end of the West arm of Castaic Lake. Water supply California State Aqueduct water en route to Southern California is pumped up through the Tehachapi Mountains (by the Edmonston Pumping Plant) to the Tehachapi Afterbay. There the aqueduct divides into East and West Branches. The West Branch water is again pumped at the Oso Pumping Plant to Quail Lake, near Highway 138 ...

Water Tunnels In The United States
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers a ...

California Department Of Water Resources
The California Department of Water Resources (DWR) is part of the California Natural Resources Agency and is responsible for the management and regulation of the State of California's water usage. The department was created in 1956 by Governor Goodwin Knight following severe flooding across Northern California in 1955, where they combined the Division of Water Resources of the Department of Public Works with the State Engineer's Office, the Water Project Authority, and the State Water Resources Board. It is headquartered in Sacramento. History 1850-1875 California recognizes many types of water rights. Prior to the Treaty of Guadalupe Hidalgo, signed in 1848, California was part of Mexico. Riparian rights were the most prevalent type of water right. Under riparian rights, which have their origins in Roman law, a landowner can use water flowing by his property for use on his property. When California became part of the United States, the United States agreed to recognize exist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castaic Lake
Castaic Lake ( Chumash: ''Kaštiq'') is a reservoir formed by Castaic Dam on Castaic Creek, in the Sierra Pelona Mountains of northwestern Los Angeles County, California, United States, near the town of Castaic. The California Office of Environmental Health Hazard Assessment has issued a safety advisory for any fish caught in Castaic Lake and Castaic Lagoon due to elevated levels of mercury and PCBs. Description The lake, with a surface elevation of approximately above sea level, is the terminus of the West Branch California Aqueduct, though some comes from the Castaic Creek watershed above the dam. Castaic Lake is bisected by the Elderberry Forebay Dam, which creates the adjacent Elderberry Forebay. The aqueduct water comes from Pyramid Lake through the Angeles Tunnel and is used to power Castaic Power Plant, a pumped-storage hydroelectric facility on the northern end of the forebay. Water is mostly powering the turbines, rather than being pumped by them. Castaic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elderberry Forebay
Elderberry Forebay is a small reservoir in Los Angeles County, California, which serves as the pumping forebay of the Castaic Power Plant. It located at the upper end of the larger Castaic Lake and is separated from the lake by Elderberry Forebay Dam at its southern edge. Entering the northern end of the forebay is the west branch of the California Aqueduct, which connects the forebay to Pyramid Lake through the Angeles Tunnel. A component of the California State Water Project, the reservoir was partitioned from Castaic Lake in 1974 to store water for pumped-storage hydroelectricity Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing.

Peak Demand
Peak demand on an electrical grid is simply the highest electrical power demand that has occurred over a specified time period (Gönen 2008). Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand fluctuations may occur on daily, monthly, seasonal and yearly cycles. For an electric utility company, the actual point of peak demand is a single half-hour or hourly period which represents the highest point of customer consumption of electricity. At this time there is a combination of office, domestic demand and at some times of the year, the fall of darkness. Some utilities will charge customers based on their individual peak demand. The highest demand during each month or even a single 15 to 30 minute period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Tunnel (physical Infrastructure)
Water tunnels are tunnels (below-ground channels) used to transport water to areas with large populations or agriculture. They are frequently part of aqueducts. Some aqueducts, such as the Delaware Aqueduct are single long tunnels. In other cases, such as the San Jacinto tunnel on the Colorado River Aqueduct, water tunnels form parts of far longer aqueducts. In cases where the outflow of a water tunnel is into an existing stream or river flowing to the point of water use, the term aqueduct is less likely to be used, as with the Harold D. Roberts Tunnel from Dillon Reservoir to the North Fork South Platte River. Notable water tunnels, or systems including water tunnels *Alva B.

California Aqueduct
The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California. Named after California Governor Edmund Gerald "Pat" Brown Sr., the over aqueduct is the principal feature of the California State Water Project. The aqueduct begins at the Clifton Court Forebay at the southwestern corner of the Sacramento–San Joaquin River Delta. The aqueduct then heads south, eventually splitting into three branches: the Coastal Branch, ending at Lake Cachuma in Santa Barbara County; the West Branch, conveying water to Castaic Lake in Los Angeles County; and the East Branch, connecting Silverwood Lake in San Bernardino County. The Department of Water Resources (DWR) operates and maintains the California Aqueduct, including one pumped-storage hydroelectric plant, Gianelli Power Plant. Gianelli is located at the base of San Lu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
