Hornsdale Wind Farm
The Hornsdale Wind Farm is an electricity generator in the locality of Hornsdale in the south-west of the Narien Range, north of Jamestown, South Australia. It consists of 99 wind turbines with a generation capacity of . The plant is owned and operated by Neoen, a French renewable energy company. The electricity generated by Hornsdale Wind Farm is contracted to be supplied to the Australian Capital Territory. Construction The "Balance of Plant" civil engineering and site works for the wind farm was performed by Catcon for all three stages of construction. The wind turbine generators were imported from Denmark, and the towers from Vietnam. They were commissioned by Siemens Australia. Before the whole wind farm was commissioned, Hornsdale was generating 86 MW immediately prior to the 2016 South Australian blackout in September 2016. Operation The wind farm supplies 1 TWh/year to the 275 kV grid from 3.2 MW direct-drive turbines (no gearbox). The 100 MW Phase 2 tested supp ...

South Australia
South Australia (commonly abbreviated as SA) is a States and territories of Australia, state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria (Australia), ...

Nukunu
Nukunu are an Aboriginal Australian people of South Australia, living around the Spencer Gulf area. In the years after British colonisation of South Australia, the area was developed to contain the cities of Port Pirie and Port Augusta. Name Both the Ngaiawang people of the Lower Murray and the Adelaide region's Kaurna used their variant pronunciation for the Nukuni, ''nokunno'' and ''nokuna'', to signify an assassin, a mythical figure who was given to roaming about at night in search of people to kill. Language Nukunu language, together with Ngadjuri, with which it has a 90% overlap, is broadly classified by Luise Hercus, following the taxonomy of Wilhelm Schmidt, as belonging to the Miru cluster of the Thura-Yura languages. Country According to Norman Tindale's calculations, the Nukunu possessed approximately of tribal land. This lay on the eastern side of Spencer Gulf, from a point just north of the mouth of the Broughton River and the vicinity of Crystal Brook to Po ...

Load Management
Load management, also known as demand-side management (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. This can be achieved by direct intervention of the utility in real time, by the use of frequency sensitive relays triggering the circuit breakers (ripple control), by time clocks, or by using special tariffs to influence consumer behavior. Load management allows utilities to reduce demand for electricity during peak usage times (peak shaving), which can, in turn, reduce costs by eliminating the need for peaking power plants. In addition, some peaking power plants can take more than an hour to bring on-line which makes load management even more critical should a plant go off-line unexpectedly for example. Load management can also help reduce harmful emissions, since peaking plants or backup generators are often dirtier and less efficient than base load pow ...

Electrek
''Electrek'' is an American news website dedicated to electric transportation and sustainable energy. Electrek is known for its extensive, positive coverage of electric transportation in general and Tesla specifically. Their positive coverage of Tesla has been criticized by some automotive journalists. Its main authors have disclosed ownership of Tesla stock, substantial profit from referrals to Tesla, and ownership of Tesla cars. The owner, Seth Weintraub, also disclosed near total divestment from Tesla stock on January 14, 2020.

Rolling Blackout
A rolling blackout, also referred to as rota or rotational load shedding, rota disconnection, feeder rotation, or a rotating outage, is an intentionally engineered electrical power shutdown in which electricity delivery is stopped for non-overlapping periods of time over different parts of the distribution region. Rolling blackouts are a last-resort measure used by an electric utility company to avoid a total blackout of the power system. Rolling blackouts are a measure of demand response if the demand for electricity exceeds the power supply capability of the network. Rolling blackouts may be localised to a specific part of the electricity network, or they may be more widespread and affect entire countries and continents. Rolling blackouts generally result from two causes: insufficient generation capacity or inadequate transmission infrastructure to deliver power to where it is needed. Rolling blackouts are also used as a response strategy to cope with reduced output beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synchronverter
Synchronverters or virtual synchronous generators are inverters which mimic synchronous generators (SG) to provide "synthetic inertia" for ancillary services in electric power systems. Inertia is a property of standard synchronous generators associated with the rotating physical mass of the system spinning at a frequency proportional to the electricity being generated. Inertia has implications towards grid stability as work is required to alter the kinetic energy of the spinning physical mass and therefore opposes changes in grid frequency. Inverter-based generation inherently lacks this property as the waveform is being created artificially via power electronics. Background Standard inverters are very low inertia elements. During transient periods, which are mostly because of faults or sudden changes in load, they follow changes rapidly and may cause a worse condition, but synchronous generators have a notable inertia that can maintain their stability. The grid is design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery use ...

Hornsdale Power Reserve
Hornsdale Power Reserve is a 150 MW (194 MWh) grid-connected energy storage system owned by Neoen co-located with the Hornsdale Wind Farm in the Mid North region of South Australia, also owned by Neoen. The original installation in 2017 was the largest lithium-ion battery in the world at 129 MWh and 100 MW. It was expanded in 2020 to 194 MWh at 150 MW. Despite the expansion, it lost that title in August 2020 to the Gateway Energy Storage in California, USA. The larger Victorian Big Battery began operations in December 2021. During 2017 Tesla, Inc. won the contract and built the Hornsdale Power Reserve, for a capital cost of A$90 million, leading to the colloquial Tesla big battery name. In November 2019, Neoen confirmed that it was increasing capacity by a further 50MW/64.5MWh to a combined 193.5 MWh. The increased storage capacity was installed by March 23, 2020, and the increased power became operational in early September 2020. Construction South Austra ...
