Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage.
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.
Puget Sound Energy (PSE) is an energy utility company based in the U.S. state of Washington that provides electrical power and natural gas to the Puget Sound region. The utility serves electricity to more than 1.1 million customers in Island, King, Kitsap, Kittitas, Pierce, Skagit, Thurston, and Whatcom counties, and provides natural gas to 750,000 customers in King, Kittitas, Lewis, Pierce, Snohomish and Thurston counties. The company's electric and natural gas service area spans 6,000 square miles (16,000 km2).
India is the third largest producer of electricity in the world. During the fiscal year (FY) 2021–22, the total electricity generation in the country was 1,719 TWh, of which 1,484 TWh was generated by utilities.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.
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 to increase investment and competition in this sector of the economy.
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production.
The energy policy of India is to increase the locally produced energy in India and reduce energy poverty, with more focus on developing alternative sources of energy, particularly nuclear, solar and wind energy. Net energy import dependency was 40.9% in 2021-22.
Brazil is the 10th largest energy consumer in the world and the largest in South America. At the same time, it is an important oil and gas producer in the region and the world's second largest ethanol fuel producer. The government agencies responsible for energy policy are the Ministry of Mines and Energy (MME), the National Council for Energy Policy (CNPE), the National Agency of Petroleum, Natural Gas and Biofuels (ANP) and the National Agency of Electricity (ANEEL). State-owned companies Petrobras and Eletrobras are the major players in Brazil's energy sector, as well as Latin America's.
Chile's total primary energy supply (TPES) was 36.10 Mtoe in 2014. Energy in Chile is dominated by fossil fuels, with coal, oil and gas accounting for 73.4% of the total primary energy. Biofuels and waste account for another 20.5% of primary energy supply, with the rest sourced from hydro and other renewables.
According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. In 2014, Canada consumed the equivalent of 85.7 megatonnes worth of oil of hydroelectricity, 9.8% of worldwide hydroelectric consumption. Furthermore, hydroelectricity accounted for 25.7% of Canada's total energy consumption. It is the third-most consumed energy in Canada behind oil and natural gas.
Romania is the 38th largest energy consumer in the world and the largest in South Eastern Europe as well as an important producer of natural gas, oil and coal in Europe.
As of April 2020, the energy sector in Senegal has an installed capacity of 1431 megawatts (MW). Energy is produced by private operators and sold to the Senelec energy corporation. According to a 2020 report by the International Energy Agency, Senegal had nearly 70% of the country connected to the national grid. Current government strategies for electrification include investments in off-grid solar and connection to the grid.
Energy in Armenia is mostly from natural gas. Armenia has no proven reserves of oil or natural gas and currently imports most of its gas from Russia. The Iran-Armenia Natural Gas Pipeline has the capacity to equal imports from Russia.
China's electric power industry is the world's largest electricity producer, passing the United States in 2011 after rapid growth since the early 1990s. In 2019, China produced more electricity than the next three countries—U.S., India, and Russia—combined.
The electricity sector in Sri Lanka has a national grid which is primarily powered by hydroelectric power and thermal power, with sources such as photovoltaics and wind power in early stages of deployment. Although potential sites are being identified, other power sources such as geothermal, nuclear, solar thermal and wave power are not used in the power generation process for the national grid.
NTPC Limited, formerly known as National Thermal Power Corporation, is an Indian central Public Sector Undertaking under the ownership of the Ministry of Power, Government of India which is engaged in generation of electricity and allied activities. The headquarters of the PSU are situated at New Delhi. NTPC's core function is the generation and distribution of electricity to State Electricity Boards in India. The body also undertakes consultancy and turnkey project contracts that involve engineering, project management, construction management, and operation and management of power plants.
