The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry. The commercial distribution of electric power started in 1882 when electricity was produced for electric lighting. In the 1880s and 1890s, growing economic and safety concerns lead to the regulation of the industry. What was once an expensive novelty limited to the most densely populated areas, reliable and economical electric power has become an essential aspect for normal operation of all elements of developed economies.
India is the third largest producer of electricity in the world. The national electric grid in India has an installed capacity of 393.389 GW as of 31 December 2021. Renewable power plants, which also include large hydroelectric plants, constitute 37% of India's total installed capacity. During the fiscal year (FY) 2019-20, the gross electricity generated by utilities in India was 1,383.5 TWh and the total electricity generation in the country was 1,598 TWh. The gross electricity consumption in FY2019 was 1,208 kWh per capita. In FY2015, electric energy consumption in agriculture was recorded as being the highest (17.89%) worldwide. The per capita electricity consumption is low compared to most other countries despite India having a low electricity tariff.
The electricity sector in Canada has played a significant role in the economic and political life of the country since the late 19th century. The sector is organized along provincial and territorial lines. In a majority of provinces, large government-owned integrated public utilities play a leading role in the generation, transmission, and distribution of electricity. Ontario and Alberta have created electricity markets in the last decade in order to increase investment and competition in this sector of the economy.
Power Grid Corporation of India Limited is an Indian statutory corporation under the jurisdiction of Ministry of Power, Government of India and is headquartered in Gurugram, India and engaged mainly in transmission of bulk power across different states of India. Power Grid transmits about 50% of the total power generated in India on its transmission network. It is also certified for PAS 99:.
The Tanzania Electric Supply Company Limited (TANESCO) is a Tanzanian parastatal organisation established in 1964. It is wholly owned by the government of Tanzania. The Ministry of Energy and Minerals regulates the operations of TANESCO.
Kerala State Electricity Board Ltd (KSEBLtd) is a public sector undertaking under the Government of Kerala, India, that generates, transmits and distributes electricity in the state. Established in 1957, the agency comes under the authority of the Department of Power. It has been registered under Indian companies act during January 2011.
The Central Electricity Authority of India (CEA) advises the government on policy matters and formulates plans for the development of electricity systems. It is a statutory organisation constituted under section 3(1) of Electricity Supply Act 1948, which has been superseded by section 70(1) of the Electricity Act 2003.
The electricity sector in Honduras has been shaped by the dominance of a vertically integrated utility ; an incomplete attempt in the early 1990s to reform the sector; the increasing share of thermal generation over the past two decades; the poor financial health of the state utility Empresa Nacional de Energía Eléctrica (ENEE); the high technical and commercial losses in transmission and distribution; and the low electric coverage in rural areas.
The electricity sector in Colombia is dominated by large hydropower generation (65%) and thermal generation (35%). Despite the country's large potential in new renewable energy technologies, this potential has been barely tapped. A 2001 law designed to promote alternative energies lacks certain key provisions to achieve this objective, such as feed-in tariffs, and has had little impact so far. Large hydropower and thermal plants dominate the current expansion plans. The construction of a transmission line with Panama, which will link Colombia with Central America, is underway.
As of August 2020 Chile had diverse sources of electric power: for the National Electric System, providing over 99% of the county's electric power, hydropower represented around 26.7% of its installed capacity, biomass 1.8%, wind power 8.8%, solar 12.1%, geothermal 0.2%, natural gas 18.9%, coal 20.3%, and petroleum-based capacity 11.3%. Prior to that time, faced with natural gas shortages, Chile began in 2007 to build its first liquefied natural gas terminal and re-gasification plant at Quintero near the capital city of Santiago to secure supply for its existing and upcoming gas-fired thermal plants. In addition, it had engaged in the construction of several new hydropower and coal-fired thermal plants. But by July 2020 91% of the new capacity under construction was of renewable power, 46.8% of the total solar and 25.6% wind, with most of the remainder hydro.
As required by the Constitution, the electricity sector is federally owned, with the Federal Electricity Commission essentially controlling the whole sector; private participation and foreign companies are allowed to operate in the country only through specific service contracts. Attempts to reform the sector have traditionally faced strong political and social resistance in Mexico, where subsidies for residential consumers absorb substantial fiscal resources.
Nicaragua is the country in Central America with the lowest electricity generation, as well as the lowest percentage of population with access to electricity. The unbundling and privatization process of the 1990s did not achieve the expected objectives, resulting in very little generation capacity added to the system. This, together with its high dependence on oil for electricity generation, led to an energy crisis in 2006 from which the country has not fully recovered yet.
The power sector in the Dominican Republic has traditionally been, and still is, a bottleneck to the country's economic growth. A prolonged electricity crisis and ineffective remedial measures have led to a vicious cycle of regular blackouts, high operating costs of the distribution companies, large losses including electricity theft through illegal connections, high retail tariffs to cover these inefficiencies, low bill collection rates, a significant fiscal burden for the government through direct and indirect subsidies, and very high costs for consumers as many of them have to rely on expensive alternative self-generated electricity. According to the World Bank, the revitalization of the Dominican economy depends greatly on a sound reform of the sector.
Availability Based Tariff (ABT) is a frequency based pricing mechanism applicable in India for unscheduled electric power transactions. The ABT falls under electricity market mechanisms to charge and regulate power to achieve short term and long term network stability as well as incentives and dis-incentives to grid participants against deviations in committed supplies as the case may be.
Delhi Transco Limited (DTL), formerly Delhi Power Supply Company Limited (DPSCL) is the State Transmission Utility for the National Capital Territory of Delhi. It is responsible for the transmission of power at 220 kV and 400 kV level and for upgrading, operating and maintaining the high voltage network.
The National Grid is the nationwide system of electric power transmission in New Zealand. The national electricity transmission grid is owned, operated, and maintained by state-owned enterprise Transpower New Zealand, although some lines are owned by local distribution companies and leased to Transpower. In total, the national grid contains 11,803 kilometres (7,334 mi) of high-voltage lines and 178 substations.
The electricity sector of the United States includes a large array of stakeholders that provide services through electricity generation, transmission, distribution and marketing for industrial, commercial, public and residential customers. It also includes many public institutions that regulate the sector. In 1996, there were 3,195 electric utilities in the United States, of which fewer than 1,000 were engaged in power generation. This leaves a large number of mostly smaller utilities engaged only in power distribution. There were also 65 power marketers. Of all utilities, 2,020 were publicly owned, 932 were rural electric cooperatives, and 243 were investor-owned utilities. The electricity transmission network is controlled by Independent System Operators or Regional Transmission Organizations, which are not-for-profit organizations that are obliged to provide indiscriminate access to various suppliers in order to promote competition.
Central Electricity Regulatory Commission (CERC), a key regulator of power sector in India, is a statutory body functioning with quasi-judicial status under sec – 76 of the Electricity Act 2003. CERC was initially constituted on 24 July 1998 under the Ministry of Power's Electricity Regulatory Commissions Act, 1998 for rationalization of electricity tariffs, transparent policies regarding subsidies, promotion of efficient and environmentally benign policies, and for matters connected Electricity Tariff regulation. CERC was instituted primarily to regulate the tariff of Power Generating companies owned or controlled by the government of India, and any other generating company which has a composite scheme for power generation and interstate transmission of energy, including tariffs of generating companies.
Russia is the fourth largest generator and consumer of electricity in the world. Its 440 power stations have a combined installed generation capacity of 220 GW.
The Electricity Act 1989 provided for the privatisation of the electricity supply industry in Great Britain, by replacing the Central Electricity Generating Board in England and Wales and by restructuring the South of Scotland Electricity Board and the North of Scotland Hydro-Electric Board. The Act also established a licensing regime and a regulator for the industry called the Office of Electricity Regulation (OFFER), which has since become the Office of Gas and Electricity Markets (OFGEM).
