National Grid (New Zealand)
The National Grid is the nationwide system of electric power transmission in New Zealand. The grid is owned, operated and maintained by Transpower New Zealand, a state-owned enterprise, although some lines are owned by local distribution companies and leased to Transpower. In total, the national grid contains of high-voltage lines and 178 substations. Much of New Zealand’s electricity generation is hydroelectric, the majority of which is from power stations on lakes and rivers in the lower half of the South Island, while most of the electricity demand is in the North Island, in particular, the Auckland region. Consequently, large amounts of electricity need to be transmitted long distances from power stations to electricity users, including transmission across Cook Strait through the HVDC Inter-Island link. Investments in new transmission are regulated by the Electricity Commission and the Commerce Commission. In a news release in January 2012, the Commerce Commission report ...

Bullendale
Bullendale is an abandoned mining settlement in Otago, New Zealand. It is the site of New Zealand's first industrial hydro-electric power plant. Located in rugged and remote countryside, it has survived to become of historical significance, and several archaeological surveys have been conducted there. Phoenix Mine, Battery and Power Plant The 20 stamp battery was originally powered mechanically by a water turbine fed from a miners water race. However the lack of water during dry weather prompted the call for power to be provided from an electric generating plant using water from the nearby Skippers Creek, a tributary of the Shotover River.Martin, p. 19-21 The battery was upgraded to 30 stamps in anticipation of the increased power supplied by the electric system. Electricity generation began in 1886 with two dynamos, giving a maximum combined capacity of . There was a two mile long transmission line from the generating station to the stamping battery. However, this early system p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Addington, New Zealand
Addington is a major suburb of Christchurch, New Zealand. It is sited south-west of the city centre. As an inner city suburb, Addington has a mix of residential, retail and light industrial properties. History 19th century For the first decade after the founding of Christchurch in 1850, Addington was farmland, consisting of large rural sections. In the early 1860s, the railway was surveyed through the area and subdivision of the larger sections began. Factories moved in; wool and grain sheds opened; and with the industry came working class residential settlement. Development continued throughout the 19th century: the city's sale yards opened in 1874 and the railway workshops were moved to Addington in 1880. By the time the show grounds were opened in 1887, Addington had become an important suburb in the industrial and social life of Christchurch. In 1874 the Addington Prison was built in Lincoln Road; it closed in 1999 and the Mountfort cell block and remaining perimeter w ...

Coleridge Power Station
The Coleridge Power Station is a hydroelectric facility at Lake Coleridge on the Rakaia River in Canterbury, New Zealand. The power station is owned and operated by TrustPower. History Coleridge was New Zealand's first major power station in which the state was involved. It was constructed mainly to supply electricity to Christchurch, with construction beginning in 1911 and completed with three generating units in 1914. For the most part it was built by hand, with some heavier work done by steam shovels. Following its initial construction, the twin 66 kV transmission lines connecting the power station with Christchurch's Addington substation were the highest voltage in New Zealand, and the longest at over long. In the early years of the station, demand for electricity in Christchurch grew rapidly and the transmission system extended to reach Rangiora in the north and Oamaru in the south. The limited capacity at Coleridge resulted in regular interruptions to supply. To remedy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waikino
Waikino is a small settlement at the eastern end of a gorge in the North Island of New Zealand alongside the Ohinemuri River, between Waihi and the Karangahake Gorge. The Waikino district lies at the base of the ecologically sensitive Coromandel Peninsula with its subtropical rainforests, steep ravines and fast moving rivers and streams.

Horahora Power Station
Horahora Power Station was an early hydroelectric power station on the Waikato River in New Zealand. It was the country’s first large-scale power station, completed in 1913. Initially built to service a gold mine, the power station was expanded to supply a significant part of the North Island. The power station remained in use until was submerged by Lake Karapiro, which was formed to supply the larger Karapiro Power Station. History Horahora power station was built by the Waihi gold mining company to provide power for mining operations at Waihi, about 80 km away. Construction began in 1910 and took three years, continuing through the Waihi miners' strike despite attempts to involve the Horahora construction workers in the strike action. When the power station opened in October 1913 it was the largest generating plant in the country with a capacity of . The power was put to use throughout the mine and stamping mills, however under the mining company’s ownership the pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okere Falls Power Station
Okere Falls Power Station is a hydroelectric power station that came into production in May 1901, bringing electricity to Rotorua. At the time, Rotorua was only the fourth town in New Zealand to have electricity. The power station was the first power station built by the New Zealand government, and it remained in operation until 1936. History With Rotorua's expanding tourism industry in the 19th century, demand grew for having electrical lighting. In 1897, land was secured at Okere Falls for a powerhouse, followed by a tender in 1899 to build a hydro-electric power plant.Information contained on "Power for People" information panel at the viewing platform over Okere Falls. Rotorua's demand for electricity grew rapidly and by 1907 could not be met by the existing turbine anymore. In 1908, a new wing dam out from the head gates into the river was completed, bringing in enough water to run a second turbine, doubling the station's output to .

Overhead Power Line
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electrical cables (commonly multiples of three for three-phase power) suspended by towers or poles. Since most of the insulation is provided by the surrounding air, overhead power lines are generally the least costly method of power transmission for large quantities of electric energy. Construction Towers for support of the lines are made of wood either grown or laminated, steel or aluminum (either lattice structures or tubular poles), concrete, and occasionally reinforced plastics. The bare wire conductors on the line are generally made of aluminum (either plain or reinforced with steel or composite materials such as carbon and glass fiber), though some copper wires are used in medium-voltage distribution and low-voltage connections to customer premises. A major goal of overhead power line d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
