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.
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. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time.
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).
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.
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.
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.
Iran has the fourth largest oil reserves and the 2nd largest natural gas reserves in the world. The nation is a member of OPEC, and generates approximately 50% of state revenue through oil exports.
Energy consumption across Russia in 2020 was 7,863 TWh. Russia is a leading global exporter of oil and natural gas and is the fourth highest greenhouse emitter in the world. As of September 2019, Russia adopted the Paris Agreement In 2020, CO2 emissions per capita were 11.2 tCO2.
The Chalk Point Generating Station is an electricity-generating plant, comprising oil and natural gas fired units, owned by NRG Energy, located near the town of Eagle Harbor, Maryland, United States, on the Patuxent River.
Through the 1996 Electric Utilities Act the Alberta's deregulated electricity market began.
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.
As a modern European nation, nuclear energy is used in Slovenia for many peaceful civilian purposes including electricity production, medicine, and research.
Total primary energy supply (TPES) in Slovenia was 6.80 Mtoe in 2019. In the same year, electricity production was 16.1 TWh, consumption was 14.9 TWh.
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 biomass, or relatively constant sources, such as geothermal power.
Iru Power Plant is a co-generation power plant in Iru village, Maardu, Estonia. It is owned by Enefit Green, a subsidiary of Eesti Energia. The plant has a heating capacity of 698 MWt.
The Šoštanj Power Plant, also known as the Sostanj Thermal Power Plant, is a lignite, heating oil and natural gas fueled power station on the bank of the Paka River near Šoštanj, Slovenia. Termoelektrarna Šoštanj is the owner and operator of the plant; TEŠ is fully owned by Holding Slovenske Elektrarne (HSE), which is 100% held by the Republic of Slovenia.
World energy supply and consumption is global production and preparation of fuel, generation of electricity, energy transport, and energy consumption. It is a basic part of economic activity. It includes heat, but not energy from food.
