Orion New Zealand Limited
Orion New Zealand Limited (Orion) is an electricity distribution company, based in Christchurch, New Zealand. The company was formed under its current name in December 1998. Orion is owned by Christchurch City Council (89.3%) and Selwyn District Council (10.7%). In 2013, Orion posted a $49m profit, with $32m in dividends going to the shareholding councils. Its last CEO was Roger Sutton, who resigned to become CEO of the Canterbury Earthquake Recovery Authority on 13 June 2011. Orion is responsible for electricity distribution in Christchurch and the Selwyn District, bounded to the north and south by the Waimakariri and Rakaia Rivers and to the east and west by the Southern Alps and the Pacific Ocean respectively. Within this region, it delivers 3,165 gigawatt-hours of electricity per year to 190,000 customers. History Prior to 1989, electricity distribution and retailing in Christchurch and Selwyn was the responsibility of four entities: the Christchurch City Council Munici ...

Christchurch
Christchurch ( ; mi, Ōtautahi) is the largest city in the South Island of New Zealand and the seat of the Canterbury Region. Christchurch lies on the South Island's east coast, just north of Banks Peninsula on Pegasus Bay. The Avon River / Ōtākaro flows through the centre of the city, with an urban park along its banks. The city's territorial authority population is people, and includes a number of smaller urban areas as well as rural areas. The population of the urban area is people. Christchurch is the second-largest city by urban area population in New Zealand, after Auckland. It is the major urban area of an emerging sub-region known informally as Greater Christchurch. Notable smaller urban areas within this sub-region include Rangiora and Kaiapoi in Waimakariri District, north of the Waimakariri River, and Rolleston and Lincoln in Selwyn District to the south. The first inhabitants migrated to the area sometime between 1000 and 1250 AD. They hunted moa, which ...

Single Wire Earth Return
Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. Its distinguishing feature is that the earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or ''neutral wire'') to act as a return path. Single-wire earth return is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps. It is also used for high-voltage direct current over submarine power cables. Electric single-phase railway traction, such as light rail, uses a very similar system. It uses resistors to earth to reduce hazards from rail voltages, but the primary return currents are through the rails. History Lloyd Mandeno, OBE (1888–1973) fully developed SWER in New Zealand around 1925 for rural electrification. Although he termed it "Earth Working Single Wir ...

Energy Companies Established In 1998
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 m ...

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 ...
