Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Roxburgh
Roxburgh () is a civil parish and formerly a royal burgh, in the historic county of Roxburghshire in the Scottish Borders, Scotland. It was an important trading burgh in High Medieval to early modern Scotland. In the Middle Ages it had at least as much importance as Edinburgh, Stirling, Perth, or Berwick-upon-Tweed, for a time acting as ''de facto'' capital (as royal residence of David I). History Its significance lay in its position in the centre of some of Lowland Scotland's most agriculturally fertile areas, and its position upon the River Tweed, which allowed river transport of goods via the main seaport of Berwick-upon-Tweed. Its position also acted as a barrier to English invasion. Standing on a defensible peninsula between the rivers Tweed and Teviot, with Roxburgh Castle guarding the narrow neck of the peninsula, it was a settlement of some importance during the reign of David I who conferred Royal Burgh status upon the town. At its zenith, between the reigns of Willi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roxburgh Dam
The Roxburgh Dam is the earliest of the large hydroelectricity, hydroelectric projects in the lower half of the South Island of New Zealand. It lies across the Clutha River, Clutha River / Mata-Au, some from Dunedin, some to the north of the town of Roxburgh, New Zealand, Roxburgh. The settlement of Lake Roxburgh Village is close to the western edge of the dam. History Development In 1944 the State Hydro Department estimated that even with the power stations currently under construction they would only be able to meet projected South Island load up until 1950 or 1951 and that a new large power station was required. Detailed investigations by the Public Works Department identified two alternatives, Black Jack's Point on the Waitaki River (where eventually Benmore Power Station would be built) and Roxburgh Gorge on the Clutha River. A power station at Roxburgh had the advantage of being less remote, requiring less geological investigation, half the materials for the same power ...

Wairakei
Wairakei is a small settlement, and geothermal area a few kilometres north of Taupō, in the centre of the North Island of New Zealand, on the Waikato River. It is part of the Taupō Volcanic Zone and features several natural geysers, hot pools. boiling mud pools, and the Wairakei Power Station, a major geothermal electric power generating station. The station was the second large-scale geothermal facility worldwide, and was commissioned in 1958. It was listed in the book ''70 Wonders Of The Modern World'' published in 2000 by Reader's Digest to record ''The Eventful 20th Century''. The settlement, referred to as Wairakei Village, was constructed to house the workers of both the power station and the neighbouring Aratiatia hydro power station. From 31 October 2022 it had buses to Taupō, Mondays to Fridays. Demographics Statistics New Zealand describes Wairakei Village as a rural settlement, which covers . The settlement is part of the larger Wairakei-Broadlands statistical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poihipi Power Station
The Poihipi Power Station is a geothermal power station owned and operated by Contact Energy. It is located on Poihipi Road near Taupo in New Zealand. The plant produces around 350 GWh pa, utilising geothermal steam from the Wairakei field, and is operated as part of the Wairakei geothermal system. Development The station has had an extraordinarily contentious history. In the beginning, Alistair McLachlan and his wife Ava Marie ran a sheep farm for their Waituruturu trust, but also a greenhouse to grow roses and orchids in "artificial monsoon" conditions enabled by geothermal heat: approximately two square kilometres of their land overlay the Wairakei geothermal field. Their Waituruturu trust joined with Mercury Network (wholly owned subsidiary of Mercury Energy) to form a joint venture, Mercury Geotherm Limited, (33% owned by the McLauchlans, or 49% according to the N.Z. Herald, 11 January 2005) and Poihipi Land Limited, wholly owned by MGL. Some land was for the power stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohaaki Power Station
The Ohaaki Power Station is a geothermal power station owned and operated by Contact Energy. A distinctive feature of this power station is the 105 m high natural draft cooling tower, the only one of its kind in New Zealand. Although initially constructed to generate 104 MW, decline in the steamfield has meant maximum net capacity is about 65 MW with an annual output of around 400 GWh pa. There are currently three turbines in operation. One smaller turbine runs off high pressure steam which then backfeeds into the main intermediate pressure system that feeds the two main units. Condensers on the back end of the main turbines are fed cooled water from the cooling tower to condense the steam back into water. Additional condensate gained in this process is reinjected back into the ground. In 2013, the Waikato Regional Council granted resource consents for a term of 35 years and for a take of 40,000 tonnes per day of geothermal fluid. Ohaaki Marae The plant is located adjacent to ...

Clyde, New Zealand
Clyde, formerly Dunstan, is a small town in Central Otago, New Zealand with a population of in It is located on the Clutha River, between Cromwell and Alexandra. Clyde grew up around the former settlement of Dunstan during the Central Otago goldrush of the 1860s. The town could once claim to be the most populous in New Zealand during the height of gold fever. The town's post office (and thus the town) was officially renamed from Dunstan to Clyde on 22 May 1865, after Lord Clyde. More recently the town has been known for the Clyde Dam, a giant hydroelectric dam at the north end of the town, behind which lies Lake Dunstan. The Clutha River is the swiftest river (per volume) in the southern hemisphere. The river then runs to the Roxburgh Dam before finally meeting the sea at Balclutha. The town is a popular holiday spot. It lies at the western end of the Otago Central Rail Trail. The Otago Central Branch Railway originally terminated at Cromwell, but this section of the rai ...

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.

Clyde Dam
The Clyde Dam, New Zealand's third-largest hydroelectric dam, is built on the Clutha River / Mata-Au near the town of Clyde. It is owned and operated by Contact Energy. History There was considerable controversy when the dam was planned because it would flood many houses and orchards upstream at Cromwell, as well as the scenic Cromwell Gorge, which was a highlight of the then young but growing New Zealand tourism industry. Construction also required replacement of a stretch of highway and the closure of the Otago Central Railway beyond Clyde, though materials for the dam would provide significant traffic for the rest of the line which was experiencing a drop in freight tonnage. To mitigate these problems, the Kirk Labour government decided a low dam should be built at Clyde. This decision was overturned by the following National government, who preferred a high dam. There was also debate about whether the dam was needed. National's support for a controversial aluminium smelter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
