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, which is a kind of gas-fired power 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.

Vasilikos Power Station is the newest power plant of Electricity Authority of Cyprus. Located between Larnaca and Limassol and with an installed capacity of 640 MW, it was still under development prior to the Evangelos Florakis Naval Base explosion of 11 July 2011.
The Littlebrook Power Station were a series of four oil and coal-fired power stations situated on the south bank of the River Thames, next to the Queen Elizabeth 2 Bridge and the Dartford Tunnel in Dartford, Kent. The final power station, Littlebrook D, ceased operating in March 2015, and has now been demolished.
The Tilbury power stations were two thermal power stations on the north bank of the River Thames at Tilbury in Essex. The 360 MW dual coal- and oil-fired Tilbury A Power Station operated from 1956 until 1981 when it was mothballed, prior to demolition in 1999. The 1,428 MW Tilbury B Power Station operated between 1968 and 2013 and was fueled by coal, as well as co-firing with oil and, from 2011, biomass. Tilbury B was demolished in 2016–19. Since 2013 three other power stations have been proposed or constructed in Tilbury.
Carrington Power Station is a combined cycle gas turbine power station, which was completed in Autumn 2016 and began commercial operation on 18 September 2016. It is located on the site of a former coal-fired power station, close to the villages of Carrington and Partington in the Greater Manchester Area and 12 km (7.5 mi) southwest of Manchester City Centre. The Manchester Ship Canal and the River Mersey run alongside the site, in Trafford, Greater Manchester, in North West England.
The Ceylon Electricity Board - CEB, is the largest electricity company in Sri Lanka. With a market share of nearly 100%, it controls all major functions of electricity generation, transmission, distribution and retailing in Sri Lanka. It is one of the only two on-grid electricity companies in the country; the other being Lanka Electricity Company (LECO). The company earned approximately Rs 204.7 billion in 2014, with a total of nearly 5.42 million consumer accounts. It is a government-owned and controlled utility of Sri Lanka that takes care of the general energy facilities of the island. The Ministry of Power and Energy is the responsible ministry above the CEB. Ceylon Electricity Board (CEB), established by the CEB Act No. 17 of 1969, is under the legal obligation to develop and maintain an efficient, coordinated and economical system of electricity supply in accordance with any licenses issued.
The Lakvijaya Power Station is the largest power station in Sri Lanka.
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.
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering.
The Mampuri Wind Farms are a set of three wind farms located near the Lakvijaya Power Station, on the Kalpitiya peninsula, in Mampuri, Puttalam District, Sri Lanka. The wind farms, referred to as Mampuri-I, Mampuri-II, and Mampuri-III, was built successively, and consists of eighteen Suzlon wind turbines ranging from 1.25 MW to 2.10 MW. Mampuri-I was commissioned on 22 March 2010, and was the first wind farm in the country to reach the 10 MW installed capacity threshold. As the government only allows projects up to 10 MW, the three wind farms are registered under three different company names, namely Senok Wind Power, Senok Wind Energy, and Senok Wind Resource.
The Broadlands Dam is a 35 MW run-of-the-river hydroelectric complex currently under construction in Kitulgala, Sri Lanka. The project is expected to be completed in 2020, and will consist of two dams, and a power station downstream.
The Yugadanavi Power Station is a large oil-fired power station in Sri Lanka. The 300 MW power station is located in Kerawalapitiya, in the Western Province of Sri Lanka.
The Kankesanthurai Power Station was a fuel oil-run thermal power station which was commissioned as part of the urgent plan by the Ceylon Electricity Board to overcome the 1990s power crisis. Construction of the power station began in August 1998, and the power station was commissioned three months later on 4 November 1998 in Kankesanthurai, in the Jaffna Peninsula of Sri Lanka. It was the biggest power station in the Jaffna region, at that time.
The Sojitz Kelanitissa Power Station, is privately owned 172 MW diesel-fired combined cycle power station located in Kelanitissa, in the city of Colombo, Sri Lanka. It is owned by Sojitz Kelanitissa Private Limited, a subsidiary of Sojitz Corporation. The power station is located adjacent to the Kelanitissa Power Station, which is a separate government-owned power station.
The Thornhill power station generated and supplied electricity to the town of Dewsbury and the wider regional area from 1902 to 1982, and again from 1998. The first generating station on the site was owned and operated by the Yorkshire Electric Power Company. Following nationalisation of the British electricity supply industry in 1948 Thornhill power station was operated by a succession of state owned bodies. The power station was redeveloped with new plant in 1915, 1925, 1932–37 and 1950–54. The coal-fired steam station was decommissioned in 1982, and was subsequently demolished. A gas turbine power station on the site was commissioned in 1998.
Vallibel Power Erathna PLC is a renewable energy company in Sri Lanka. The company operates three small hydropower projects.
