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.
In electricity generation, a generator is a device that converts motive power into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids.
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.
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power.
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.
Kruonis Pumped Storage Plant is located near Kruonis, Lithuania, 34 km (21 mi) east of Kaunas. Its main purpose is to provide grid energy storage. It operates in conjunction with the Kaunas Hydroelectric Power Plant. During periods of low demand, usually at night, Kruonis PSHP raises water from the lower Kaunas reservoir to the upper one using cheap surplus energy. The station is designed to have an installed capacity of 1,600 MW but only four 225 MW generators are currently operational. With a fully filled upper reservoir the plant can generate 900 MW for about 12 hours.
Lar Dam is a dam located at the foot of Mount Damavand in Amol county, Mazandaran, Iran. The dam is located within the protected Lar National Park and situated just 70 kilometers northeast of the capital and the most populous city of the country, Tehran. The primary purpose of the dam is municipal water supply to Tehran but prior to the water reaching the city filtration plant, it is used to power the Kalan and Lavarak Hydroelectric Power Stations, with a combined installed capacity of 162.5 MW.
Tenom Pangi Dam is the hydroelectric plant in Tenom, Sabah, Malaysia. It is located 120 km (75 mi) south of Kota Kinabalu on the Padas River. The project is a run-of-river hydroelectric power plant. Tenom Pangi Dam is the only major hydroelectric dam in Sabah.
The Silahtarağa Power Station was a coal-fired generating station located in Istanbul Turkey. The Ottoman Empire's first power plant, it was in use from 1914 to 1983. The site has since been converted into a university campus for the Istanbul Bilgi University and houses two museums and several facilities. It was refurbished and renamed SantralIstanbul in 2007.
Jaruga Hydroelectric Power Plant is a hydroelectric power plant on river Krka, located in Šibenik-Knin County, in central Dalmatia, Croatia.
Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity in the United States. In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity.
The Naghlu Dam is a gravity dam on the Kabul River in Surobi District of Kabul Province in Afghanistan. It is located 40 km (25 mi) east of the nation's capital Kabul. The primary purpose of the dam is hydroelectricity production. The dam supports a power station with a design capacity of 100 MW of electricity. It is connected to the national grid of Afghanistan, and is currently the largest power plant in the country. It provides electricity to about 100,000 households in the Kabul region.
The Lanark Hydro Electric Scheme refers to two hydroelectric plants in the Clydesdale area of South Lanarkshire, Scotland. They take in water from the Falls of Clyde.
Hydroelectricity is a major source of electricity in Turkey, due to its mountainous landscape and many rivers. The country's main river basins are those of the Euphrates and the Tigris. Over 700 hydropower plants have been built, and hydroelectricity makes up about 30% of the country's electricity generating capacity. Generation can vary greatly from one year to the next, depending on rainfall. In good years, substantial amounts of hydroelectric power can be generated. Government policies have generally supported dam construction, but some dams are controversial in neighbouring countries, while others raise concerns about damage to the environment and wildlife of Turkey.
The Uganda Electricity Generation Company Limited (UEGCL) is a parastatal company whose primary purpose is to generate electric power for use in Uganda and for sale to neighboring countries. As of December 2017, UEGL's generation capacity was 380 megawatts, with that capacity planned to increase to over 1,300 megawatts, by 2023.
Okere Falls Power Station is a hydroelectric power station that came into production in May 1901, bringing electricity to Rotorua. At the time, Rotorua was only the fourth town in New Zealand to have electricity. The power station was the first power station built by the New Zealand government, and it remained in operation until 1936.
Renewable energy in Turkey is mostly hydroelectricity, geothermal energy and solar energy. Although sun and wind could supply plenty of energy in Turkey, hydropower is the only renewable energy which is fully exploited, averaging about a fifth of national electricity supply. However in drought years much less electricity is generated by hydro. Over half of capacity is renewables, and it is estimated that over half of generation could be from renewables by 2026 but Turkey has invested less in solar and wind power than similar Mediterranean countries. Turkey lacks a renewable energy plan beyond 2023 which includes transport, industry, heating and cooling as well as electricity generation. More renewable energy could be used to reduce the nation's greenhouse gas emissions and thus avoid paying other countries' carbon tariffs. The country is a net exporter of wind power equipment, but a net importer of solar power equipment. Total non-hydro renewables overtook hydro in 2021.
Turkey uses more electricity per person than the global average, but less than the European average, with demand peaking in summer due to air conditioning. Most electricity is generated from coal, gas and hydropower, with hydroelectricity from the east transmitted to big cities in the west. Electricity prices are state-controlled, but wholesale prices are heavily influenced by the cost of imported gas.
Kadıncık 1 hydroelectric plant, is a privately owned hydroelectric power station located in Mersin Province, Turkey.
