Kidston Dam
Kidston Dam also known as Copperfield Dam is a dam in Lyndhurst, Shire of Etheridge, Queensland, Australia. It is approximately north of Hughenden and was built for the Kidston Gold Mine. The mine closed July 2001. The lake created by the dam has a capacity of . History This storage and associated pipeline was built to provide water to the Kidston Goldmine in the early 1980s on the Copperfield River, a tributary of the Einasleigh River in the Gilbert River catchment. The dam was one of the first dams built in Australia using the roller compacted concrete technique. At the closure of the mine in 2001, the dam was handed back to the Queensland Government and is owned/ managed by the Queensland Department of Energy and Water Supply (DEWS). Downstream properties receive water via a pipeline which was built to supply the mine and associated township. There is also a local arrangement to release water (towards the end of winter) to fill downstream waterholes. This allows ripar ...

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, win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams Completed In 2001
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Queensland
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the ...

Redclaw
''Cherax quadricarinatus'' (known by several common names, including Australian red claw crayfish, Queensland red claw, redclaw, tropical blue crayfish, freshwater blueclaw crayfish) is an Australian freshwater crayfish. Distribution and ecology ''C. quadricarinatus'' is native to permanent freshwater streams, billabongs and lakes on the north coast of the Northern Territory, northeastern Queensland, and Papua New Guinea. Through translocation by humans, the range has spread down to southern Queensland and into the far north of Western Australia. ''C. quadricarinatus'' is considered an invasive species, and has established feral populations in South Africa, Mexico, Jamaica, Puerto Rico, Indonesia, Zambia, Malaysia and Singapore. This tropical crustacean is very tolerant of environmental changes, and is primarily a detritivore. Description The colour of ''C. quadricarinatus'' ranges from dark brown to blue-green and adult males have a distinct red patch on the outer ...

Australian Renewable Energy Agency
The Australian Renewable Energy Agency (ARENA) is an independent agency of the Australian federal government, established in 2012 to manage Australia's renewable energy programs, with the objective of increasing supply and competitiveness of Australian renewable energy sources. Background ARENA was established in 2012 as an independent statutory authority to manage the government's renewable energy programs. Legal establishment came with the passing of the Australian Renewable Energy Agency Act 2011 (ARENA Act). The legislation passed parliament in November 2011 with the support of the Australian Greens and the Liberal and National coalition opposition as well as the governing Labor Party. ARENA commenced operations on 1 July 2012. The agency resulted from negotiations within the Australian parliament under the Gillard Government, with the intention of providing more secure funding for renewable energy programs in the context of political changes. While ARENA was created ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Power Purchase Agreement
A power purchase agreement (PPA), or electricity power agreement, is a contract between two parties, one which generates electricity (the seller) and one which is looking to purchase electricity (the buyer). The PPA defines all of the commercial terms for the sale of electricity between the two parties, including when the project will begin commercial operation, schedule for delivery of electricity, penalties for under delivery, payment terms, and termination. A PPA is the principal agreement that defines the revenue and credit quality of a generating project and is thus a key instrument of project finance. There are many forms of PPA in use today and they vary according to the needs of buyer, seller, and financing counter parties. Contractual terms of a PPA may last anywhere between 5 and 20 years, during which time the power purchaser buys energy, and sometimes also capacity and/or ancillary services, from the electricity generator. Such agreements play a key role in the financin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
