Huntly, New Zealand
Huntly ( mi, Rahui-Pōkeka) (population ) is a town in the Waikato district and region of the North Island of New Zealand. It was on State Highway 1 (until Huntly bypass opened in March 2020), south of Auckland and north of Hamilton. It is situated on the North Island Main Trunk (NIMT) railway (served by Te Huia since 6 April 2021 at a rebuilt Raahui Pookeka-Huntly Station) and straddles the Waikato River. Huntly is within the Waikato District which is in the northern part of the Waikato region local government area. History and culture Originally settled by Māori, European migrants arrived in the area some time in the 1850s. The Huntly name was adopted in the 1870s when the postmaster named it after Huntly, Aberdeenshire in Scotland. He used an old 'Huntley Lodge' stamp to stamp mail from the early European settlement. The ''Lodge'' was later dropped and the spelling changed to also drop the additional 'e'. The railway from Auckland reached Huntly in 1877, when the ...

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rel ...

Electrical Substation
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Cooling Tower
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of ''dry cooling towers'', rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to tall and in diameter, or rec ...

Resource Management Act 1991
The Resource Management Act (RMA) passed in 1991 in New Zealand is a significant, and at times, controversial Act of Parliament. The RMA promotes the sustainable management of natural and physical resources such as land, air and water. New Zealand's Ministry for the Environment describes the RMA as New Zealand's principal legislation for environmental management. The RMA and the decisions made under it by district and regional councils and in courts affect both individuals and businesses in large numbers, and often in very tangible ways. The Act has variously been attacked for being ineffective in managing adverse environmental effects, or overly time-consuming and expensive and concerned with bureaucratic restrictions on legitimate economic activities. In February 2021, the Government confirmed that the RMA is to be replaced by three separate acts. These will be the Natural and Built Environment Bill (NBA), the Strategic Planning Bill (SPA), and the Climate Change Adaptat ...
