North Bank Tunnel
The North Bank tunnel concept was a hydroelectric scheme being developed by Meridian Energy on the Waitaki River in Canterbury, New Zealand. The $993 million project was expected to produce an additional per annum, and take up to of water from Lake Waitaki. The project would have resulted in a per annum reduction in output from the Waitaki hydro station. Discovery of geological faultlines prompted a rethink of the project, including consideration of using a canal instead of a tunnel. Work on the project was suspended in January 2013 due to a forecast of flat demand for electricity for the next five years. Resource consents for the scheme lapsed in 2016. This project is at a similar location to Project Aqua, a hydroelectric power proposal abandoned by Meridian in 2004. Resource consent process In December 2008, Environment Canterbury granted water use consents for this project. Appeals against this decision were made by Ngāi Tahu, Ngāi Tahu Fishers People Inc, the Lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...

Waitaki River
The Waitaki River is a large braided river that drains the Mackenzie Basin and runs some south-east to enter the Pacific Ocean between Timaru and Oamaru on the east coast of the South Island of New Zealand. It starts at the confluence of the Ōhau and Tekapo rivers, now at the head of the artificial Lake Benmore, these rivers being fed by three large glacial lakes, Pukaki, Tekapo, and Ōhau at the base of the Southern Alps. The Waitaki flows through Lake Benmore, Lake Aviemore and Lake Waitaki, these lakes being contained by hydroelectric dams, Benmore Dam, Aviemore Dam and Waitaki Dam. The Waitaki has several tributaries, notably the Ahuriri River and the Hakataramea River. It passes Kurow and Glenavy before entering the Pacific Ocean. The River lends its name the Waitaki District on the south side of the river bank. The river's flow is normally low in winter, with flows increasing in spring when the snow cloaking the Southern Alps begins to melt, with flows throughout t ...

Project Aqua
Project Aqua was a hydroelectric scheme proposed for the lower Waitaki River in New Zealand. Although the scheme had considerable support from some locals, it met with opposition from many other groups, and Meridian Energy decided in March 2004 not to go ahead with the project. The plan The plan was to divert river water at the rate of up to 280 cubic metres per second into a separate canal for six power stations. This was on top of the three dams already in the upper Waitaki. The scheme would have produced approximately 520MW of power — enough to supply a city the size of Christchurch. Objections The objections to the scheme included land issues, the disruption during construction, and concerns about the sustainability of the river. Meridian was working on a large scale mitigation process, whereby issues could be identified and mitigated, when the scheme was finally canceled. Abandonment and impact On 29 March 2004, Meridian announced that they would not continue with Project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environment Court Of New Zealand
The Environment Court of New Zealand ( mi, Te Kōti Taiao o Aotearoa) is a specialist court for plans, resource consents and environmental issues. It mainly deals with issues arising under the Resource Management Act, meaning that it covers a wide range of potential future effects of planning applications, which can include such areas as traffic congestion, noise/pollution emissions and social and commercial consequences, rather than just the 'ecological' aspects that could be implied by the 'environmental' term. History The history of independent appeal courts addressing environmental matters began with the establishment of Appeal Boards under the Town and Country Planning Act 1953. The first planning appeals were heard in February 1955. The Appeal Boards were replaced by the Planning Tribunal following the passing of the Town and Country Planning Act 1977. The Environment Court replaced the Planning Tribunal as a result of the Resource Management Amendment Act 1996. Jurisdic ... [...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.
