Atiamuri Power Station
Ātiamuri Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It is the third of eight hydroelectric power stations on the Waikato River. The station can easily be seen from State Highway 1 between Taupō and Tokoroa. Ātiamuri Power Station is downstream of Ōhakuri Power Station, and takes water directly from the larger upstream station. The relatively small storage of Lake Ātiamuri means the timing of Ātiamuri's generation production is critical, particularly if Ōhakuri is generating at full capacity. Ātiamuri, like all of the hydroelectric power stations on the Waikato River, is operated by state-owned electricity generator Mercury Energy. History Ātiamuri was the fifth hydroelectric power station on the Waikato River to be built. Construction of the station, as well as Ōhakuri and Waipāpa, was approved by the Government, and construction of the dam and power station began in November 1953. The Government engag ...

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] |
Mangakino
Mangakino is a small town on the banks of the Waikato River in the North Island of New Zealand. It is located close to the hydroelectric power station at Lake Maraetai, southeast of Hamilton. The town and its infrastructure are administered as the Mangakino Pouakani ward by the Taupō District Council. History and culture In 1896, (after 40 years of resistance) the British Crown acquired the Wairarapa Lakes from Ngāti Kahungunu and in 1915, gave in return land in middle North Island, land known as part of the Pouakani Block. At that time the land where Mangakino lies today was described as native bush and pumice wastelands, barren, unoccupied and unfarmed. In 1946, as the Karapiro Dam neared completion, workers were to transfer to the next dam construction site – 'Maraetai I', near Mangakino. The Crown, under the Public Works Act, reacquired a portion of the unoccupied Pouakani Block alongside the Waikato River to build a "hydroelectric station" and a temporary township, ...

Energy Infrastructure Completed In 1958
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bay Of Plenty
The Bay of Plenty ( mi, Te Moana-a-Toi) is a region of New Zealand, situated around a bight of the same name in the northern coast of the North Island. The bight stretches 260 km from the Coromandel Peninsula in the west to Cape Runaway in the east. The Bay of Plenty Region, governed by the Bay of Plenty Regional Council, incorporates several large islands in the bay, in addition to the mainland area. Called ''Te Moana-a-Toi'' (the Sea of Toi) in the Māori language after Toi, an early ancestor, the name 'Bay of Plenty' was bestowed by James Cook in 1769 when he noticed the abundant food supplies at several Māori villages there, in stark contrast to observations he had made earlier in Poverty Bay. History According to local Māori traditions, the Bay of Plenty was the landing point of several migration canoes that brought Māori settlers to New Zealand. These include the ''Mātaatua'', ''Nukutere'', ''Tākitimu'', '' Arawa'' and ''Tainui'' canoes. Many of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whakamaru
Whakamaru is a town in the central region of the North Island of New Zealand. The Maori words 'whaka' and 'maru' literally mean to give shelter to, or safeguard. History The Whakamaru supervolcano eruption (dated to 320–340,000 years ago) is the largest known eruption from the area known as the Taupo Volcanic Zone (TVZ) and means the town is located in the historic Whakamaru caldera. The name is a shortened version of Te Whakamarumarutanga o Kahukeke ("The Shelter of Kahukeke"). According to Waikato Tainui oral traditions, Kahukeke, the Māori healer and explorer, who had arrived in New Zealand on the ''Tainui'' migratory canoe fell ill at the spot and the area was named for the shelter where she recovered. In some versions the shelter was built by her husband Rakatāura / Hape, the tohunga of the ''Tainui''. The town of Whakamaru was originally established as accommodation for the Whakamaru Power Station in New Zealand. The Whakamaru switching station, adjacent to ...

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...
