Cobb Power Station
The Cobb Power Station is a hydroelectric facility on the Cobb River, northwest of Nelson, New Zealand. Since 2003, it has been owned and operated by Trustpower. Annual generation is approximately . It is fed by the Cobb Reservoir and has a head of , the highest of any power station in New Zealand. From the reservoir, a long tunnel leads through the Cobb Range to the penstocks. The water flow is channelled via two long penstocks and the height difference between the intake and the power station results in a high pressure water flow of 7.25 m³/s to feed the six Pelton turbines. Cobb Power Station can be reached from Upper Tākaka via a sealed but winding and narrow road along Tākaka River. The power station building is situated at the edge of Kahurangi National Park, with the reservoir located entirely within the national park, another further up an unsealed steep and winding road.

Tasman, New Zealand
Tasman District () is a local government district in the northwest of the South Island of New Zealand. It borders the Canterbury Region, West Coast Region, Marlborough Region and Nelson City. It is administered by the Tasman District Council, a unitary authority, which sits at Richmond, with community boards serving outlying communities in Motueka and Golden Bay / Mohua. The city of Nelson has its own unitary authority separate from Tasman District, and together they comprise a single region in some contexts, but not for local government functions or resource management (planning) functions. Name Tasman Bay, the largest indentation in the north coast of the South Island, was named after Dutch seafarer, explorer and merchant Abel Tasman. He was the first European to discover New Zealand on 13 December 1642 while on an expedition for the Dutch East India Company. Tasman Bay passed the name on to the adjoining district, which was formed in 1989 largely from the merger of Waimea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelton Wheel
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled overland to take part in the California Gold Rush ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 1956
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] |
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.

Electricity Sector In New Zealand
The electricity sector in New Zealand uses mainly renewable energy, such as hydropower, geothermal power and increasingly wind energy. , 82% of electricity is generated from renewable sources, making New Zealand one of the countries with the lowest carbon dioxide emissions from electricity generation. Electricity demand grew by an average of 2.1% per year from 1974 to 2010 but decreased by 1.2% from 2010 to 2013. The electricity market is regulated by the Electricity Authority. Electricity lines businesses, including Transpower and the distribution lines companies, are regulated by the Commerce Commission. Control is also exerted by the minister of energy in the New Zealand Cabinet, though the minister for state-owned enterprises and the minister for climate change also have some powers by virtue of their positions and policy influence in the government. History In New Zealand electricity was first generated within factories for internal use. The first generation plant where ...

Kahurangi National Park
Kahurangi National Park in the northwest of the South Island of New Zealand is the second largest of the thirteen national parks of New Zealand. It was gazetted in 1996 and covers , ranging to near Golden Bay in the north. Much of what was the North-west Nelson Forest Park formed the basis of the new park. Kahurangi Point, regarded as the boundary between the West Coast and Tasman Regions, is located in the park, as is Mount Owen. The main tramping tracks in the park are the Heaphy Track and the Wangapeka Track. The park is administered by the Department of Conservation. Tramping, rafting and caving are popular activities in the park. After being prohibited for several years, mountainbiking was allowed on the Heaphy Track on a trial basis for the winters of 2011, 2012 and 2013. The effect of the cyclists on trampers and the wildlife were to determine whether the trial continued or not. Endangered takahē were reintroduced to the park in 2018, which was 100 years after ...

Department Of Conservation (New Zealand)
The Department of Conservation (DOC; Māori: ''Te Papa Atawhai'') is the public service department of New Zealand charged with the conservation of New Zealand's natural and historical heritage. An advisory body, the New Zealand Conservation Authority (NZCA) is provided to advise DOC and its ministers. In addition there are 15 conservation boards for different areas around the country that provide for interaction between DOC and the public. Function Overview The department was formed on 1 April 1987, as one of several reforms of the public service, when the ''Conservation Act 1987'' was passed to integrate some functions of the Department of Lands and Survey, the Forest Service and the Wildlife Service. This act also set out the majority of the department's responsibilities and roles. As a consequence of Conservation Act all Crown land in New Zealand designated for conservation and protection became managed by the Department of Conservation. This is about 30% of New Z ...

The dam that forms the reservoir was built from 1949 to 1954, replacing a smaller structure built about ten years earlier. It is an earth dam high by long. The geology of the area precluded the construction of a concrete dam. A narrow winding road leads over Cobb Ridge to Cobb Reservoir and along the lake's shore, providing access to tramping tracks in the area surrounding the valley. The road was built in the 1940s and remains unsea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
