New Plymouth Power Station
The New Plymouth Power Station (NPPS) was a 600 MW thermal power station at New Plymouth, New Zealand. Located at Port Taranaki, it was dual fuelled on natural gas and fuel oil. Constructed at a time of major hydro and HV transmission developments, it was New Zealand's first big thermal power station planned for continuous base load operation. The plant has been owned and operated (in turn) by NZED, NZE, ECNZ and Contact Energy. In 2013, the site was sold to Port Taranaki and Methanex. History The power station project commenced in the 1960s, to meet rising electricity demand in New Zealand. Initially, fuel for this power station was to be coal, barged up from the West Coast, and the Port Taranaki site was chosen ahead of one at Wanganui. During early stages of the project, the Maui gas field was discovered off Taranaki. The plant design was changed to be dual fuel on either natural gas or heavy fuel oil. The first unit was commissioned in February 1974, with the fif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Taranaki
Port Taranaki is a port complex located in New Plymouth, New Zealand 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 count .... It is the only deep water port on the west coast of New Zealand, and is owned by the Taranaki Regional Council. The port handles a wide range of coastal and international cargoes, mostly relating to the farming, engineering and petrochemical industries. Adjacent features include the city of New Plymouth, the New Plymouth Power Station and the Sugar Loaf Islands Marine Protected Area (SLIMPA). History The port was established in 1875, and construction of the main breakwater began in 1881 with Frederic Carrington ceremoniously laying the first stone.

Maui Gas Field
The Maui natural gas field is the largest gas, natural gas condensate and oil field in New Zealand, producing nearly three-quarters of the country's hydrocarbons, as well as providing energy for electricity generation. It is located in the Tasman Sea, 35 km off the coast of Taranaki and to the southwest of New Plymouth. It covers an area of 157 square kilometres and is located in 110 metres of water. The gas field was discovered in 1969 by a joint venture of Royal Dutch/Shell, British Petroleum and Todd Petroleum. It was considered a "giant" field at the time of discovery. Government investment led to a government organisation later called Petrocorp taking a 50% interest. This was later bought out by Fletcher Challenge Energy. By the end of the Maui gas contract in 2009, the Maui Mining Companies were made up of Shell (83.75%), OMV New Zealand (10%), and Todd Energy (6.25%). OMV New Zealand owns and operates the Maui gas field having acquired the 83.75% share from Shell Explor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In New Plymouth
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas-fired Power Stations In New Zealand
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Electricity Sector In New Zealand
The electricity sector in New Zealand uses mainly renewable energy, such as Hydroelectricity, hydropower, geothermal energy, 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 New Zealand electricity market, electricity market is regulated by the Electricity Authority (New Zealand), Electricity Authority. Electricity lines businesses, including Transpower New Zealand, 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 governme ...

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.

Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

Combined Cycle
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otahuhu Power Station
The Otahuhu power station was a power station site located in Otara, Auckland, New Zealand. Two plants operated on the site: Otahuhu A (initially open cycle gas turbines, then synchronous compensation) and Otahuhu B (a 404 MW combined cycle). A proposed third station, Otahuhu C, was never built. The stations were owned by Contact Energy. The site was sold by Contact in 2016. Otahuhu A (OTG) The first generating units at Otahuhu were open cycle gas turbine Stal-Laval units, commissioned in 1968. The plant comprised four 45 MW gas turbine units. In 1978, a further two generating units were added, twin pack units using Rolls-Royce Olympus gas turbines. The Otahuhu A gas turbines were retired from electricity generation in the late 1990s, however they remained in continuous service providing reactive power to Transpower NZ, owner of the national grid. In November 2013, the generators were retired from service and decommissioned. Otahuhu B (OTC) The combined cycle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kapuni
Kapuni is an onshore natural gas-condensate field located in the Taranaki Basin, a ~100,000 km2 partially-inverted rift basin on the Taranaki Peninsula in the North Island, New Zealand. Discovered in 1959 and brought into production in 1970, Kapuni remained New Zealand's only producing gas-condensate field until the offshore Maui gas field began production in 1979. Geology Geologic history During the Lower Cretaceous (~150–100 Ma) Rangitata Orogeny, an accretionary wedge accumulated and was uplifted on the margin of Gondwana in present-day New Zealand. The resulting topography was eroded throughout the Cretaceous. After the Rangitata Orogeny, seafloor spreading commenced during the Middle Cretaceous. This resulted in the formation of the Tasman Sea as New Zealand separated from Australia. Normal faults, including the Manaia Fault, formed as the Taranaki Basin developed during seafloor spreading. Rifting continued until the Eocene (~56 Ma), when the Taranaki Basin under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
