Hydroelectric Power In New Zealand
Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island. Early schemes such as the Waipori scheme commissioned in 1903 and the Lake Coleridge power station commissioned in 1914 established New Zealand's use of renewable hydro energy. By the early 1950s, over of installed capacity was from hydro energy. By the early 1960s, most North Island hydro sites had been developed while the South Island still had many potential sites. The commissioning of the HVDC Inter-Island link in 1965 made it possible to send large amounts of electricity between the two islands, and from that time hydro capacity in the South Island increased rapidly. Major developments included the 540 MW Benmore Power Station (1966), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roaring Meg Power Station Otago Aug 2007
A roar is a type of animal vocalization that is loud, deep and resonating. Many mammals have evolved to produce roars and other roar-like vocals for purposes such as long-distance communication and intimidation. These include various species of big cats, bears, pinnipeds, bovids, deer, elephants and simians. The anatomical basis for the ability to roar often involves modifications to the larynx and hyoid bone and enlarged internal air spaces for low-frequency vocal resonation. While roaring, animals may stretch out their necks and elevate their heads to increase the space for resonance. Definition The definition of "roar" has varied between species. However Weissengruber et al. (2002) has given a more general description of roars as consisting of both a low pitch and low formant. They have used the roars of lions and red deer as quintessential examples of the sound. Other researchers have mentioned similar "roar-like" vocalizations where either the pitch or formant is still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Tekapo
Lake Tekapo () is the second-largest of three roughly parallel lakes running north–south along the northern edge of the Mackenzie Basin in the South Island of New Zealand (the others are Lake Pukaki and Lake Ōhau). It covers an area of and is at an altitude of above sea level. In Māori culture "Tekapo" is a misspelling of , the name of the lake in the Māori language. means "to leave in haste at night". In 2021, the Mackenzie District Council announced that it will start using the dual names of Tekapo and Takapō when referring to Lake Tekapo. According to Ngāi Tahu mythology, Lake Tekapo being one of the lakes dug by the Waitaha (South Island iwi), Waitaha explorer Rākaihautū using his Polynesian digging stick, which was called Tūwhakaroria. After arriving in the Uruao waka (canoe), waka at Nelson, Rākaihautū divided his people into two groups.

MacKenzie Basin
The Mackenzie Basin (), popularly and traditionally known as the Mackenzie Country, is an elliptical intermontane river basin, basin located in the Mackenzie District, Mackenzie and Waitaki Districts, near the centre of the South Island of New Zealand. It is the largest such basin in New Zealand. Historically famous mainly for sheep farming, the sparsely populated area is now also a popular tourism destination. The basin was named in the 1850s by and after James Mckenzie (outlaw), James Mckenzie, a shepherd and would-be farmer of Scottish origin. Mckenzie was captured for allegedly stealing sheep; he herded his flocks in what was then an area almost totally empty of any human habitation, though Māori people, Māori previously lived there intermittently. After his capture, the area was soon divided up amongst new sheep pasture stations in 1857. Geography The basin extends approximately north to south, and east to west. The Southern Alps constitute its western edge. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roxburgh Dam
The Roxburgh Dam is the earliest of the large hydroelectric projects in the lower half of the South Island of New Zealand. It lies across the Clutha River / Mata-Au, some from Dunedin, some to the north of the town of 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 output and a better climate in which to undertake co ...

Clutha River
The Clutha River (, officially gazetted as Clutha River / ) is the second longest river in New Zealand and the longest in the South Island. It flows south-southeast through Central and South Otago from Lake Wānaka in the Southern Alps to the Pacific Ocean, south west of Dunedin. Gold is in abundance in the Clutha River and its surrounding areas. It is the highest volume river in New Zealand, and has a discharging mean flow of . The Clutha River played a prominent role in both the Māori and European history of the area. Rivers and valleys were the main transport system used by local Māori to access the interior of the South Island. The 1860s Otago gold rush resulted in the production of approximately 240 tonnes of gold, which was found in the Clutha catchment. It has the biggest catchment and outflow in New Zealand. About 6% of all water in the South Island is discharged by the Clutha River alone. It has a mean discharge of approximately and a catchment area of around ...

Waikato River
The Waikato River is the longest river in New Zealand, running for through the North Island. It rises on the eastern slopes of Mount Ruapehu, joining the Tongariro River system and flowing through Lake Taupō, New Zealand's largest lake. It then drains Taupō at the lake's northeastern edge, creates the Huka Falls, and flows northwest through the Waikato Plains. It empties into the Tasman Sea south of Auckland, at Port Waikato. It gives its name to the Waikato region that surrounds the Waikato Plains. The present course of the river was largely formed about 17,000 years ago. Contributing factors were climate warming, forest being reestablished in the river headwaters and the deepening, rather than widening, of the existing river channel. The channel was gradually eroded as far up river as Piarere, leaving the old Hinuera channel through the Hinuera Gap high and dry. The remains of the old course are seen clearly at Hinuera, where the cliffs mark the ancient river edges. The Wai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
