In the electricity sector in the United Kingdom the National Grid is the high-voltage electric power transmission network serving Great Britain, connecting power stations and major substations and ensuring that electricity generated anywhere on it can be used to satisfy demand elsewhere. The network covers the great majority of Great Britain and several of the surrounding islands. It does not cover Northern Ireland, which is part of a single electricity market with the Republic of Ireland.
Rural electrification is the process of bringing electrical power to rural and remote areas. Rural communities are suffering from colossal market failures as the national grids fall short of their demand for electricity. As of 2017, over 1 billion people worldwide lack household electric power – 14% of the global population. Electrification typically begins in cities and towns and gradually extends to rural areas, however, this process often runs into obstacles in developing nations. Expanding the national grid is expensive and countries consistently lack the capital to grow their current infrastructure. Additionally, amortizing capital costs to reduce the unit cost of each hook-up is harder to do in lightly populated areas. If countries are able to overcome these obstacles and reach nationwide electrification, rural communities will be able to reap considerable amounts of economic and social development.
National Grid plc is a multinational electricity and gas utility company headquartered in London, England. Its principal activities are in the United Kingdom, where it owns and operates electricity and natural gas transmission networks, and in the Northeastern United States, where as well as operating transmission networks, the company produces and supplies electricity and gas, providing both to customers in New York, Massachusetts, and Rhode Island.
The East–West Interconnector is a 500 MW high-voltage direct current submarine and subsoil power cable which connects the Irish and British electricity markets. The project was developed by the Irish national grid operator EirGrid.
Country Energy, an Australian energy retail subsidiary of Origin Energy, provides natural gas and electricity to retail customers in New South Wales, Victoria, Queensland, South Australia and the Australian Capital Territory.. Since its establishment in 2001 and until 28 February 2011, Country Energy was owned by the Government of New South Wales.
Guthega Power Station is located in the Snowy Mountains region of New South Wales, Australia. The power station's purpose is for the generation of electricity. It is the first to be completed and smallest of the initial seven hydroelectric power stations that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.
Solar power represented a very small part of electricity production in the United Kingdom (UK) until the 2010s when it increased rapidly, thanks to feed-in tariff (FIT) subsidies and the falling cost of photovoltaic (PV) panels.
Chichester Dam is a minor concrete gravity dam across the Chichester and Wangat rivers, upstream of Dungog, in the Hunter Region of New South Wales, Australia. The dam's main purpose is water supply for the Lower Hunter region. A mini hydro-electric power station operates at times of peak flow and is connected to the national grid. The impounded reservoir is Lake Chichester.
The Electricity Commission of New South Wales, sometimes called Elcom, was a statutory authority responsible for electricity generation and its bulk transmission throughout New South Wales, Australia. The Commission was established on 22 May 1950 by the Electricity Commission Act 1950 to take control of power generation in the State. The Commission acquired the power stations and main transmission lines of the four major supply authorities: Southern Electricity Supply, Sydney County Council, the Department of Railways and the Electric Light and Power Supply Corporation Ltd, known as the Balmain Electric Light Company, to acquire the Balmain Power Station. The Commission was responsible for the centralised co-ordination of electricity generation and transmission in the State, and some local councils continued to be distributors of electricity only.
TransGrid is the manager and operator of the high voltage electricity transmission network in New South Wales and the Australian Capital Territory, Australia, and is part of the National Electricity Market (NEM). The company's offices are located in Sydney, Newcastle, Orange, Tamworth, Wagga, and Yass.
A super grid or supergrid is a wide-area transmission network, generally trans-continental or multinational, that is intended to make possible the trade of high volumes of electricity across great distances. It is sometimes also referred to as a "mega grid". Super grids typically are proposed to use high-voltage direct current (HVDC) to transmit electricity long distances. The latest generation of HVDC power lines can transmit energy with losses of only 1.6% per 1,000 km.
New Electricity Trading Arrangements (NETA) is the system of market trading arrangements under which electricity is traded in the United Kingdom's wholesale electricity market as of 27 March 2001. The arrangements provided that parties could trade off their imbalances close to real time.
Power System Operation Corporation Limited (POSOCO) is a division of Power Grid Corporation of India which is under the jurisdiction of Ministry of Power, Government of India. It is responsible to monitor and ensure round the clock integrated operation of Indian Power System in a reliable, efficient and secure manner thus serving a mission critical activity. It consists of 5 Regional Load Despatch Centres (RLDCs) and the National Load Despatch Centre (NLDC).
The United Kingdom has a National Grid that covers most of mainland Great Britain and several of the surrounding islands, as well as some connectivity to other countries. In 2020 the electricity sector's grid supply came from 55% low-carbon power, 36.1% fossil fuelled power, and 8.4% imports. Renewable power is showing strong growth, while fossil fuel generator use in general and coal use in particular is shrinking, with historically dominant coal generators now mainly being run in winter due to pollution and costs, and contributed just 1.6% of the supply in 2020.
Rèinigeadal is a small settlement in Harris, in the Western Isles in Scotland. It is situated on the east coast of Harris 8 kilometres east of Tarbert, at the western side of the entrance to Loch Seaforth. Rèinigeadal is situated within the parish of Harris. Rèinigeadal had no road access until 1990; the only route in was 5 kilometres along a hill path, or by boat. The road now links to the A859.
As of 2018, hydroelectric power stations in the United Kingdom accounted for 1.87 GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.
Powerlink Queensland is an electricity transmission system operator owned by the Government of Queensland which operates the high-voltage electricity transmission infrastructure in Queensland.
The Energy Networks Association (ENA) is the industry body funded by UK gas and electricity transmission and distribution licence holders.
The electricity sector in Australia is historically dominated by coal-fired power stations, but renewables are forming a rapidly growing fraction of supply.
