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, using for example, the pumped-storage method.
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.
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand.
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, the sun or hydro-electric installations. 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.
Hybrid power are combinations between different technologies to produce power.
A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost, cost of electricity and capacity factor.
The production of renewable energy in Scotland is a topic that came to the fore in technical, economic, and political terms during the opening years of the 21st century. The natural resource base for renewable energy is high by European, and even global standards, with the most important potential sources being wind, wave, and tide. Renewables generate almost all of Scotland's electricity, mostly from the country's wind power.
Renewable energy in Australia is based mainly on biomass, solar, wind, and hydro generation technologies. Over a third of all electricity generated in Australia is renewable energy, a proportion that is increasing in line with global trends, with a target to phase out coal power before 2040. In 2021 Australia overtook China in terms of renewable energy proportion, and as of 2024 has almost caught up with the European Union, but is still far behind Germany who overtook Australia in 2004. Wind and rooftop solar energy in particular have grown since 2010.
Wind power has a history in Canada dating back many decades, particularly on prairie farms. As of December 2021, wind power generating capacity was approximately 14,304 megawatts (MW). Combined with 2,399 MW of solar power generating capacity, this provided about 6.5% of Canada's electricity demand as of 2020. The Canadian Wind Energy Association (CanWEA) has outlined a future strategy for wind energy that would reach a capacity of 55 GW by 2025, meeting 20% of the country's energy needs.
Musselroe Wind Farm is a wind farm at Cape Portland, Tasmania, Australia. It was the third wind farm built in the state, following the Bluff Point and Studland Bay Wind Farms.
Policy makers often debate the constraints and opportunities of renewable energy.
Energy in Jordan describes energy and electricity production, consumption and import in Jordan. Jordan is among the highest in the world in dependency on foreign energy sources, with 92.3% of the country's energy supply being imported.
Variable renewable energy (VRE) or intermittent renewable energy sources (IRES) are renewable energy sources that are not dispatchable due to their fluctuating nature, such as wind power and solar power, as opposed to controllable renewable energy sources, such as dammed hydroelectricity or bioenergy, or relatively constant sources, such as geothermal power.
Solar power in Mexico has the potential to produce vast amounts of energy. 70% of the country has an insolation of greater than 4.5 kWh/m2/day. Using 15% efficient photovoltaics, a square 25 km (16 mi) on each side in the state of Chihuahua or the Sonoran Desert could supply all of Mexico's electricity.
Renewable energy in Taiwan contributed to 8.7% of national electricity generation as of end of 2013. The total installed capacity of renewable energy in Taiwan by the end of 2013 was 3.76 GW.
Energy in the Faroe Islands is produced primarily from imported fossil fuels, with further contributions from hydro and wind power. Oil products are the main energy source, mainly consumed by fishing vessels and sea transport. Electricity is produced by oil, hydropower and wind farms, mainly by SEV, which is owned by all the municipalities of the Faroe Islands. The Faroe Islands are not connected by power lines with continental Europe, and thus the archipelago cannot import or export electricity.
Guernsey Electricity Limited (GE) is the sole commercial electricity supplier on the island of Guernsey. GE has been operating for over 100 years, moving from local generation of power from coal, and later oil, to investing in cables to connect into the grids in Jersey and France through the Channel Islands Electricity Grid.
ACEN Corporation, formerly AC Energy, is the energy firm under the Ayala Group. The company has over 4,000 MW of attributable capacity in the Philippines, Vietnam, Indonesia, India, and Australia, with a renewable share of 98% which is among the highest in the region.
Tasmania, as an advanced economy with a globally high standard of living, uses a great deal of energy. Distinctive features of energy use in Tasmania include the high fraction of hydroelectricity usage, the absence of coal-fired electrical generation, relatively light usage of natural gas, particularly for domestic use, and a wide use of domestic wood-burning stoves. Energy production through hydroelectricity has been politically contentious, and conflicts over Tasmanian hydroelectric projects were integral to the formation of Green parties in Australia and across the world.
Romblon Wind Farm is a wind farm in Romblon, Romblon, Philippines. The wind farm uses three units of 41.5-meter (136 ft) high Komaihaltec KWT300 wind turbines erected on the hills of Barangays Agnay, Bagacay and Lonos in Romblon, Romblon. The wind farm is a project of Romblon Electric Cooperative (ROMELCO) and was made possible through a funding grant from Japanese companies Komaihaltec Inc. and Honda Motor Co. Ltd. The wind turbines were erected in 2018 and began operation in 2019. Under the contract between ROMELCO, Komaihaltec Inc., and Honda Motor Co. Ltd., the wind farm will be turned over to ROMELCO in 2023 after a four-year demonstration period.
