Hydroelectric
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.

Meridian Energy
Meridian Energy Limited is a New Zealand electricity generator and retailer. The company generates the largest proportion of New Zealand's electricity, generating 35 percent of the country's electricity in the year ending December 2014, and is the fourth largest retailer, with 14 percent of market share in terms of customers as of December 2015. Meridian was one of three electricity companies formed from the break-up of the Electricity Corporation of New Zealand (ECNZ) in 1998–99, taking over the Waitaki River and the Manapouri hydro schemes. Originally a state-owned enterprise wholly owned by the New Zealand Government, the company was partially privatised in October 2013 by the Fifth National Government, with the government retaining a 51.02% shareholding. Today, Meridian operates seven hydroelectric power stations and one wind farm in the South Island of New Zealand, four wind farms in the North Island, and two wind farms in southern Australia – one in South Australia a ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Twizel
Twizel () is the largest town in the Mackenzie District, in the Canterbury Region of the South Island of New Zealand. The town was founded in 1968 to house construction workers on the Upper Waitaki Hydroelectric Scheme. Today, Twizel is a service and tourist town for visitors to the area. It has a resident population of during the summer, holidaymakers nearly triple the town's population. Nearby Lake Ruataniwha supports rowing, sailing and water skiing. Twizel is 37 km (29 minutes drive) east of Lake Ōhau village, 30 km (20 minutes drive) north of Omarama and 60 km (42 minutes drive) south of Lake Tekapo. History Hydro town The present town was built in 1968 by the Ministry of Works and Development as a greenfields project to house workers constructing the Upper Waitaki hydroelectricity scheme. The name comes from the nearby Twizel River, in turn named for Twizel Bridge in Northumberland by John Turnbull Thomson, Chief Surveyor of Otago in the mid-19th c ...

Lake Ruataniwha
Lake Ruataniwha is an artificial lake in the Mackenzie Basin in the South Island of New Zealand. It was formed in 1977–1981 as part of the Waitaki hydroelectric project. It lies on the traditional boundary of the Canterbury and Otago provinces, with the town of Twizel two kilometres to the north. The lake takes its name from the Ruataniwha Station, a large sheep-station in the area, part of which the NZ Electricity Department purchased as the site for the township of Twizel (founded in 1968). Ruataniwha was a Māori chief who drowned when the canoe Arai-te-uru sank near Moeraki in the 12th century CE. Features The lake is approximately 4.5 km in length and covers 3.4 square km. It was formed by the New Zealand Ministry of Works as part of the Upper Waitaki Power Project between 1977 and 1981 in a gorge created by the Ōhau River. The gorge was blocked by the building of the Ruataniwha Dam whose crest carries State Highway 8 between Twizel and Omarama. Lake Ruata ...

Lake Benmore
Lake Benmore is New Zealand's largest artificial lake. Located in the South Island of New Zealand and part of the Waitaki River, it was created in the 1960s by construction of Benmore Dam. Characteristics The lake has an area of about 75 km² and a maximum depth of 90 meters. The lake consists of two arms: the Haldon arm, fed mainly by the Tekapo, Pukaki and Twizel rivers, and the Ohau Canal; and the Ahuriri Arm, fed mainly by the Ahuriri River. Immediately downstream is Lake Aviemore. As of 2020, Land Air Water Aotearoa described the water quality as "good" and the quality of ecological conditions as "high". The lake is split between the Mackenzie, Waimate, and Waitaki districts, within the southern portion of the Canterbury Region. Construction The lake is the reservoir of Benmore Dam, New Zealand's largest earth dam, which was created as part of the Waitaki hydroelectricity power scheme. Construction of Benmore Dam was approved in 1957 and the lake was filled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Power Stations In New Zealand
This is a list of power stations in New Zealand. The list is not exhaustive – only power stations over 0.5 MW and significant power stations below 0.5 MW are listed. Power plants in New Zealand have different generating roles – for baseload, intermediate or peaking. Baseload generators are those that run continuously (except for maintenance), and include all geothermal and run-of-the-river hydroelectric plants, which must 'use it or lose it'. Intermediate generators are load-following power plants. Peaking power plants generate only for minutes or hours at a time, during the sharpest peaks in electricity demand.

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 ...
