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.

NZ Electricity Generation Capacity
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 signed the Tre ...

Arapuni Power Station
Arapuni Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It is owned and operated by Mercury Energy, and is the seventh and penultimate hydroelectric power station on the Waikato River. It is also the oldest currently generating, the first government-built, and the largest capacity single hydroelectric power station on the Waikato River. The two power houses that make up the Maraetai Power Station have a larger combined capacity however. Arapuni, due to its proximity to Hamilton, plays an important part in voltage support and frequency keeping in the city and the wider Waikato region. Even though it is 80 years old, continuous improvement and refurbishment of the station's generation equipment ensures Arapuni remains efficient. The powerhouse and dam at Arapuni are under protection of the Historic Places Trust, becoming Category I Historic Places in November 1987 and August 1991 respectively.

Aniwhenua Power Station
The Aniwhenua power station is a hydroelectric power facility in Bay of Plenty in New Zealand located on the Rangitaiki River upstream of the Matahina Power Station. Water is drawn from behind a dam above the Aniwhenua Falls and diverted through a canal and a headpond to the power station before being discharged back into the river. The power station is named after the falls which are adjacent to the power station. History Development In the late 19th century and early 20th century, numerous small local power generation stations were built by both private and local authorities. From the 1920s onward as the state electricity system expanded and the national grid was developed, development of small local power stations declined as the centralisation of electricity supply under state control increased. The 1973–74 oil shock, nation-wide electricity shortages during the winters of 1973 and 1974, a renewed policy emphasis on regional development by central government, and in ...

Wairakei Power Station
The Wairakei Power Station is a geothermal power station near the Wairakei Geothermal Field in New Zealand. Wairakei lies in the Taupo Volcanic Zone. History The power station was built in 1958, the first of its type (wet steam) in the world, and it is currently owned and operated by Contact Energy. A binary cycle power plant was constructed in 2005 to use lower-temperature steam that had already gone through the main plant. This increased the total capacity of the power station to 181MW. The Wairakei power station is due to be phased out from 2013, replaced by the Te Mihi geothermal power station. The Poihipi Power Station was built in 1996 at a nearby site in the same field. Units Wairakei A station * Unit 1 – 11.2 MW intermediate pressure * Unit 4 – 11.2 MW intermediate pressure * Unit 7 – 11.2 MW low pressure * Unit 8 – 11.2 MW low pressure * Unit 9 – 11.2 MW low pressure * Unit 10 – 11.2 MW low pressure Units 2, 3, 5 and 6 were ...

Te Mihi Power Station
The Te Mihi Power Station is a 166 MW geothermal power station owned and operated by Contact Energy, located north of Taupo in New Zealand. The resource consent for the power station was "called in" by the Minister for the Environment Trevor Mallard under the terms of the Resource Management Act. The appointed Board of Enquiry granted the consent with a set of stipulated conditions. Te Mihi Power Station uses geothermal energy from the Wairakei geothermal field, which lies in the Taupo Volcanic Zone. It is part of a plan to gradually replace the Wairakei Power Station which will be phased out of production. With Te Mihi in operation, output from Wairakei is decreased by approximately 45 MW, resulting in a net increase of about 114 MW. The project was designed and constructed by a joint venture of McConnell Dowell, SNC-Lavalin and Parsons Brinckerhoff. The plant includes two 83 MW steam turbines supplied by Toshiba. The project cost $623 million and was officially opened in ... [...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 ...
