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.
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs.
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.
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.
District heating is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants.
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.
Micro combined heat and power, micro-CHP, µCHP or mCHP is an extension of the idea of cogeneration to the single/multi family home or small office building in the range of up to 50 kW. Usual technologies for the production of heat and power in one common process are e.g. internal combustion engines, micro gas turbines, stirling engines or fuel cells.
A gas engine is an internal combustion engine that runs on a fuel gas, such as coal gas, producer gas, biogas, landfill gas, natural gas or hydrogen. In the United Kingdom and British English-speaking countries, the term is unambiguous. In the United States, due to the widespread use of "gas" as an abbreviation for gasoline (petrol), such an engine is sometimes called by a clarifying term, such as gaseous-fueled engine or natural gas engine.
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.
The electricity policy of Ontario refers to plans, legislation, incentives, guidelines, and policy processes put in place by the Government of the Province of Ontario, Canada, to address issues of electricity production, distribution, and consumption. Policymaking in the electricity sector involves economic, social, and environmental considerations. Ontario's electricity supply outlook is projected to deteriorate in the near future due to increasing demand, aging electricity supply infrastructure, and political commitments, particularly the phase-out of coal-fired generation. Policymakers are presented with a range of policy choices in addressing the situation, both in terms of overall system design and structure, and specific electricity generating technologies.
The Directive on the promotion of cogeneration based on a useful heat demand in the internal energy market and amending Directive 92/42/EEC, officially Directive 2004/8/EC, is a European Union directive for promoting the use of cogeneration, popularly better known as the 'Combined Heat and Power (CHP) Directive'.
Downtown Markham is the main central business district of Markham, Ontario, Canada. Currently under development, it is located within Markham Centre near the historic Unionville district and is proposed to serve as the heart of Markham. Businesses in the district are expected to employ up to 16,000 individuals, and it may house as many as 10,000 residents. The development plans will have a high density of residential, retail, commercial and mixed-use structures. The community is being developed, built and wholly financed by The Remington Group Inc.
Great Yarmouth Power Station is combined cycle gas turbine power station on South Denes Road in Great Yarmouth in Norfolk, England, with a maximum output of 420 MW electricity, opened in 2001. It is built on the site of an oil-fired power station, built in 1958 and closed and demolished in the 1990s. A coal-fired power station was built in Great Yarmouth in 1894 and operated until 1961. The station is operated by RWE.
Enel Russia is a Russian power generation company created by the reorganization of RAO UES, a former united power company of Russia. The company is registered in Yekaterinburg and its headquarters are in Moscow. The Italian Enel Group owns a majority stake of the company (56%).
The Avedøre Power Station is a combined heat and power station, located in Avedøre, Denmark, just south of Copenhagen, and is owned by Ørsted A/S. Avedøre Power Plant is a high-technology facility and one of the world's most efficient of its kind, being able to utilize as much as 94% of the energy in the fuel and convert 49% of the fuel energy into electricity. Apart from using petroleum (oil) and natural gas, the plant runs on a wide variety of biomass fuels such as straw and wood pellets. The plant consists of two units with a total capacity of 793 MW of electricity and 918 MW of heat. The combination of producing electricity and heat for district heating at the same time is widely used in Denmark and the rest of Scandinavia, due to the need of domestic heating together with the Danish energy companies putting a big effort into optimising the energy plants.
The T2 Energy Centre is a biomass-fuelled combined heating and power (CHP) station at Heathrow Airport in London which opened in December 2012. It provides heat to half of the active terminals: Terminal 2 and Terminal 5 and electricity into the local grid, similar to some of the airport's operations demands.
The main power supply for Shetland is provided by Lerwick Power Station, located in Gremista, 2 kilometres (1.2 mi) northwest of Lerwick town centre. This is the principal source of electrical energy for Shetland, however currently about 20 MWe is provided by the Sullom Voe Terminal power station which comprises 4 x 23 MWe Gas Turbines, the future of which is uncertain. Opened on 27 May 1953 the station is diesel-fuelled and generates a total of 66 MW of power.
Denmark is a leading country in renewable energy production and usage. Renewable energy sources collectively produced 75% of Denmark's electricity generation in 2022, and are expected to provide 100% of national electric power production from 2030. Including energy use in the heating/cooling and transport sectors, Denmark is expected to reach 100% renewable energy in 2050, up from the 34% recorded in 2021.
Blackburn power stations are a series of electricity generating stations that have provided electric power to the town of Blackburn and the wider area from 1895 to the present. The first station in Jubilee Street, Blackburn began operating in 1895. A new larger station known as Blackburn East or Whitebirk power station was commissioned in 1921 and was rebuilt in stages over the period 1942 to 1955. Whitebirk station closed in 1976. The 60 MW Blackburn Mill Combined Cycle Gas Turbine (CCGT) power station has generated electricity since 2002. The Blackburn energy from waste (EfW) plant is currently (2020) being planned.
