Heywood Interconnector
The Heywood interconnector is a 275 kV AC overhead electricity transmission line with two circuits connecting the electricity grids in South Australia and Victoria, two states of Australia. Both are part of the National Electricity Market. The nominal capacity of the interconnector is 650 MW since an upgrade in 2016. The interconnector was commissioned in 1988 and was the first connection between the two state electricity grids. Routing The Victorian end of the interconnector is the substation at Heywood. The South Australian end is the South East substation near Mount Gambier. When constructed, the Heywood Interconnector project created the new 275 kV links from South East substation through the Tailem Bend substation to the Para Substation at Gould Creek on the outskirts of Adelaide as Para was the closest 275 kV substation to Heywood at the time. The 2016 upgrade included a new substation named Black Range at Willalooka (half way between the South East and Tailem Bend subs ...

Heywood, Victoria
Heywood is a town on the Fitzroy River in the Australian state of Victoria. It is situated at an elevation of 27 metres amidst rolling green hills in an agricultural, pastoral and timbercutting district. Heywood is west of Melbourne at the intersection of the Princes and Henty Highways and north of Portland. It is on the railway line to Portland, at the junction of the presently-unused branch to Mount Gambier, South Australia. The winner of several past "Tidy Town" awards, it is often referred to as the "Jewel of the Southwest". History Prior to European settlement the area was occupied by the Gunditjmara Aborigines. David Edgar built the Bush Tavern on the townsite in 1842 and a settlement emerged. Formerly known as Fitzroy Crossing it became known as Edgar's. The township was surveyed in 1852 by Lindsay Clarke who named it after Heywood, Wiltshire in England. The first town allotments were sold in 1854 and a Post Office opened on 8 August 1857. Heywood has won many Tidy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Gambier, South Australia
Mount Gambier is the second most populated city in South Australia, with an estimated urban population of 33,233 . The city is located on the slopes of Mount Gambier, a volcano in the south east of the state, about south-east of the capital Adelaide and just from the Victorian border. The traditional owners of the area are the Bungandidj (or Boandik) people. Mount Gambier is the most important settlement in the Limestone Coast region and the seat of government for both the City of Mount Gambier and the District Council of Grant. The city is well known for its geographical features, particularly its volcanic and limestone features, most notably Blue Lake / Warwar, and its parks, gardens, caves and sinkholes. History Before British colonisation of South Australia, the Bungandidj (or Boandik) people were the original Aboriginal inhabitants of the area. They referred to the peak of the volcanic mountain as 'ereng balam' or 'egree belum', meaning 'home of the eagle hawk', but th ...

Tailem Bend, South Australia
Tailem Bend (locally, "Tailem") is a rural town in South Australia, south-east of the state capital of Adelaide. It is located on the lower reaches of the River Murray, near where the river flows into Lake Alexandrina. It is linear in layout since it is constrained by river cliffs on its western side and the Adelaide–Melbourne railway line is dominant on its eastern side. The town grew and consolidated through being a large railway centre between the 1890s and 1990s; now it continues to service regional rural communities. In the , Tailem Bend and the surrounding area had a population of 1,705. History Prior to European settlement the area was inhabited for millennia by the indigenous Ngarrindjeri people, who made bark and reed canoes and lived on fish and animals dependent on the River Murray. Once written as "Tail'em Bend", the town's name is the Ngarrindjeri word "thelim", meaning "bend", referring to the sharp bend that the river makes in this location. An alternative e ...

Gould Creek, South Australia
Gould Creek is an outer northeastern rural suburb of Adelaide, South Australia. Gould Creek is located in the City of Tea Tree Gully and City of Playford local government areas, and is adjacent to Greenwith, Salisbury Heights and Hillbank, as well as the rural districts of Yatala Vale and Upper Hermitage and the town of One Tree Hill. History European settlement Gould Creek is a creek with several fresh water springs which historically flowed into the Little Para River. The first European settlers were James Fisher (eldest son of J. H. Fisher) and Fred Handcock. The bachelor partners, aged twenty-three, first visited this locality in December 1837 when they accompanied Colonel William Light on his exploration to discover the Barossa Valley. In early 1838 they pioneered a pastoral run at the junction of Little Para River and Gould Creek. Their squatters' homestead, with mud chimney and thatched reed roof, known as Fisher and Handcock's Station, was sketched by William ...

ElectraNet
Electranet is a proposed smart electric grid which would allow people to sell electricity into the grid without any artificial caps. It was proposed in an op-ed article Al Gore wrote in a "My Turn" column for ''Newsweek'' in 2006. Like the internet, which widely distributed information, the Electranet would allow homeowners and small businesses to operate small generating power facilities and contribute to local and regional energy needs by selling power into the grid at a rate that is determined by free market forces. Like the internet, which led to a surge of productivity, the Electranet's distributed generation model is hoped to lead to innovative power generation through alternative sources and lowering greenhouse gas emissions. Electranet advocates predict that as more people participate in the Electranet, the cost of electricity will continue to go down until it becomes free. In a 2006 speech to NYU, Al Gore advocated deploying an Electranet as one way to reduce global war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electricity Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same relativ ...

National Electricity Market
The National Electricity Market (NEM) is an arrangement in Australia's electricity sector for the connection of the electricity transmission grids of the eastern and southern Australia states and territories to create a cross-state wholesale electricity market. The Australian Energy Market Commission develops and maintains the Australian National Electricity Rules (NER), which have the force of law in the states and territories participating in NEM. The Rules are enforced by the Australian Energy Regulator. The day-to-day management of NEM is performed by the Australian Energy Market Operator. NEM operations began on 13 December 1998 and currently covers Queensland, New South Wales, Australian Capital Territory, Victoria, Tasmania and South Australia. Western Australia and the Northern Territory are not connected to the NEM. The NEM comprises five regions, with the ACT being in the NSW region. Tasmania joined the NEM in May 2005 and became fully operational on 29 April 2006 when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity Grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and potential ...

Electrical Substation
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
