Wivenhoe Power Station
The Wivenhoe Power Station is situated between the Splityard Creek Dam and Lake Wivenhoe. The Splityard Creek Dam is situated in hills adjacent to Lake Wivenhoe and is about above it. The Wivenhoe Dam has been built across the Brisbane River about by road from the centre of Brisbane, the capital of the state of Queensland, Australia. The body of water held behind the dam is called Lake Wivenhoe. Operation The pumped storage hydroelectricity power station consists of two circular concrete silos, each of about internal diameter. Each of the silos houses a turbine generator spinning at 120 rpm and pump set, giving a total capacity of . During the pumping phase in the operating cycle the generator operates as a 240MW electric motor driving the pump to lift water from Lake Wivenhoe to the upper storage of the 28,600-megalitre Splityard Creek Dam. When peak demand for electricity occurs the flow of water is reversed, flowing from the upper to the lower storage and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Hydroelectric Power Stations In Australia
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, wind) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In Queensland
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. 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 to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Energy Infrastructure Completed In 1984
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Queensland has a diverse range of power generating types. Coal fired These fossil fuel power stations burn coal to power steam turbines that generate some or all of the electricity they produce. * Gladstone scheduled for closure in 2035. * Tarong scheduled for closure in 2036. * Callide B scheduled for closure in 2028. * Stanwell scheduled for closure in 2046. Gas turbine These gas turbine power stations use gas combustion to generate some or all of the electricity they produce. Combined cycle plants include an Open Cycle Gas Turbine, plus a Heat Recovery Steam Generator that uses waste heat from the gas turbine to make steam to drive a Steam Turbine. Gas (reciprocating) These power stations use gas combustion in reciprocating engines to generate some or all of the electricity they pr ...

Small Hydro
Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), " micro" (<100 kW), "" (<10 kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the at 22,500 megawatts or the vast multiple projects of the |

Queensland Government
The Queensland Government is the democratic administrative authority of the Australian state of Queensland. The Government of Queensland, a parliamentary constitutional monarchy was formed in 1859 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, Queensland has been a State of Australia, with the Constitution of Australia regulating the relationships between all state and territory governments and the Australian Government. Under the Australian Constitution, all states and territories (including Queensland) ceded powers relating to certain matters to the federal government. The government is influenced by the Westminster system and Australia's federal system of government. The Governor of Queensland, as the representative of Charles III, King of Australia, holds nominal executive power, although in practice only performs ceremonial duties. In practice executive power lies with the Premier and Cabinet. The Cabinet of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callide Power Station
Callide Power Station is an electricity generator at Mount Murchison, Queensland, Mount Murchison, Shire of Banana, Queensland, Australia. It is coal powered with eight steam turbines with a combined Electricity generation, generation capacity of 1,720 megawatts (MW) of electricity. Callide A was commissioned in 1965, refurbished in 1998 and decommissioned in 2015/16. As of 2018, generation capacity was 1510 MW. The coal for Callide comes from the nearby Callide Coalfields and water from the Lake Awoonga, Awoonga dam and Stag Creek Pipeline. An explosion and fire at the Callide C power plant in late May 2021 caused a significant power outage that affected over 375,000 premises and raised electricity prices for weeks afterwards. November 2022 all four units at the coal-fired Callide Power Station were not operating after a structural failure at the cooling plant brought the C3 unit offline, and later on the B2 unit tripped during scheduled testing, followed by the last unit, B1, ...
