Natural Gas-fired Power Stations In Tasmania
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

2016 Tasmanian Energy Crisis
The 2016 Tasmanian energy crisis was an ongoing energy storage situation in the state of Tasmania, Australia in 2016. Two years of high volumes of energy exported to Victoria via the Basslink HVDC cable, followed by low rainfall, and a fault which rendered the cable inoperable, resulted in record low storage levels in Tasmania's hydro-electric system. This resulted in a number of contingency plans to be enacted by Hydro Tasmania and the Hodgman Government. Background Tasmania's electricity generation is primarily hydro-electric, having been gradually developed since 1914. As a result, the state is highly dependent on rainfall for electricity generation. An energy shortage in the 1960s resulted in the construction of the oil-fired Bell Bay Power Station. However, this station was only used as a contingency - as of 2015, hydro-electricity continued to be the primary generation method. The state was self-reliant until 2005, when the Basslink HVDC interconnector to Victoria was com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-voltage Direct Current
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Security
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to (relatively) cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. International energy relations have contributed to the globalization of the world leading to energy security and energy vulnerability at the same time. Renewable resources exist worldwide across every biome except the North and South Poles (only nuclear (and wind in the winter) is feasible), in contrast to fossil fuels, which are concentrated in a limited number of countries. Nations don't switch from unpredictable fossil fuels to renewables overnight. It is a long, continuous process. Rapid deployment of renewable energy, increased energy efficiency, and diversification of energy sources, energy stores, and types of energy machines can use all ...

Interconnector
An interconnector (also known as a DC tie in the USA) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids. They can be formed of submarine power cables or underground power cables or overhead power lines. The longest interconnection as of July 2022 was the 2,210 km Hami - Zhengzhou delivering 8 GW of high voltage direct current power. The longest proposed connector is the 3,800 km, 3.6 GW Xlinks Morocco-UK Power Project. Economy Interconnectors allow the trading of electricity between territories. For example, the East–West Interconnector allows the trading of electricity between the UK and Ireland. A territory which generates more energy than it requires for its own activities can therefore sell surplus energy to a neighbouring territory. Interconnectors also provide increased resilience.

Basslink
The Basslink () electricity interconnector is a high-voltage direct current (HVDC) cable linking the electricity grids of the states of Victoria and Tasmania in Australia, crossing Bass Strait, connecting the Loy Yang Power Station, Victoria on the Australian mainland to the George Town substation in northern Tasmania. Basslink is bidirectional and enables Hydro Tasmania to supply some of the peak load capacity to the Australian mainland and take some of the excess power from the mainland when the generation on the mainland exceeds the demand. Financial benefits from the Basslink investment included reduced or deferred need to invest in further base load generation facilities, and potential to profit from selling peak load power into a market in which prices are generally higher, and because the cable was also used to supply power to Tasmania in times of drought, as most of Tasmania's electricity generation is hydroelectricity. A government review of Basslink in 2011 found, "Ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alinta
Alinta was an Australian energy infrastructure company. It has grown from a small, Western Australia-based gas distributor and retailer to the largest energy infrastructure company in Australia. It was bought in 2007 by a consortium including Singapore Power and various parties which include the now defunct Babcock & Brown funds. Alinta Limited was known as Westnet Infrastructure Group Limited for a time. In March 2011, due to a deleveraging transaction by the TPG Group, Alinta became Alinta Energy. Alinta Energy was acquired by Hong Kong-based Chow Tai Fook Enterprises in 2017. The successor to the retail gas business is now called Alinta Energy. History In January 1995, the vertical monopolist energy supplier, the State Energy Commission of Western Australia, was dis-aggregated into separate gas and electricity corporations, leading to the formation of AlintaGas. (The word Alinta is derived from the word for flame in a traditional language of the Yorta Yorta nation f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aurora Energy (Tasmania)
Aurora Energy is a Tasmanian Government-owned electricity retailer in Tasmania, Australia. History Aurora was formed on 1 July 1998 under the ''Electricity Companies Act 1997'' by the disaggregation of the Tasmanian Hydro Electric Commission (HEC), and is subject to the ''Corporations Act 2001''. The company is wholly owned by the Government of Tasmania, with its two shareholders being the Minister for Energy (as the Portfolio Minister) and the State Treasurer, representing the State Government on behalf of the Tasmanian community. The disaggregated of the Hydro-Electric Commission resulted in the formation of three separate state-owned companies: Hydro Tasmania, which generates the power; Transend Networks, which transmits it across the state; and Aurora Energy, the retail arm, which sells and distributes it to customers. This was in anticipation of Tasmania joining the National Electricity Market (NEM), which took place in May 2005. A subsidiary company, Aurora Energy (Tam ...

Combined Cycle
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
