The Coleridge Power Station is a hydroelectric facility at Lake Coleridge on the Rakaia River in Canterbury, New Zealand.
 The power station is owned and operated by TrustPower.
 As of 2012, the station generates 39 MW of electricity, and annual generation averages 270 GWh , following redesign of the station's turbines using Computational Fluid Dynamic modelling.
Oi Power Station (大井火力発電所 , Ōi karyokuhatsudensho ) is a large thermal power station in Shinagawa, Tokyo, Japan.
 The power station generates electricity utilizing three units of 350 MW, which run on crude oil, with a total installed capacity of 1,050 MW.
 The first unit went online in August 1971, followed by Unit 2 in February 1972, and Unit 3 in December 1973.
 The facility is located on a 190 km2 site.
The Bad Creek Hydroelectric Station is a pumped-storage hydroelectric power station located 8 mi north of Salem in Oconee County, South Carolina.
 The 1065 MW power plant is owned by Duke Energy and its last generator was commissioned in 1991.
 The power station generates electricity by shifting water between an upper and lower reservoir.
 The upper Bad Creek Reservoir was created by damming Bad Creek and West Bad Creek while Lake Jocassee serves as the lower reservoir.
 During periods of low energy demand, the four 266 MW Francis pump turbines pump water from Lake Jocassee which lies at an elevation of 1110 ft to the Bad Creek Reservoir at an elevation of 2310 ft through a 1 mi tunnel.
 When energy demand is high, water is released back from Bad Creek Reservoir back down to the pump turbines which then operate as generators.
 After electricity is produced, the water is returned to Lake Jocassee.
 The process is repeated as needed, primarily with the facility serving as a peaking power plant.
The Guodian Beilun Power Station () is a coal-fired power station in Beilun District, Ningbo, Zhejiang, China.
 With an installed capacity of 5,000 MW , it is the fourth largest coal-fired power station in the world.
 The station generates energy by five 600 MW and two 1,000 MW units, which is fuelled by coal.
Kilroot power station is a coal and oil power station on the north shore of Belfast Lough at Kilroot near Carrickfergus in Northern Ireland, UK.
 The station generates 520 megawatts (MW) of electricity from dual coal and oil fuelled generators, along with approximately 140 megawatts (MW) from four Gas Turbines and 10 MW of battery energy storage from the Kilroot Advancion Energy Storage Array.
 Since the privatisation of Northern Ireland Electricity in 1992, the power station has been owned by the AES Corporation.
 It is the only coal-fired power station operating in Northern Ireland, and produces one third of the country's electricity.
 It is also one of County Antrim's top 100 employers.
The Lough Ree Power Station is a large peat-fired power station in Lanesborough, in the Republic of Ireland.
 The station generates up 100 MWe of power, ranking as the Third largest peat-fired power station in the country, after West Offaly Power Station at 150 MWe .
 and Edenderry Power Station at 120 MWe .
 The power station was constructed as a replacement to the ageing 85 MWe Lanesborough power station.
The Markersbach Pumped Storage Power Plant is a hydroelectric power station utilizing pumped-storage technology in Markersbach, Germany.
 Planning for the power plant began in 1961, construction began in 1970 and the generators were commissioned in 1979.
 The power station generates electricity by moving water between an upper and lower reservoir.
 During periods of low energy demand, water is pumped from the lower reservoir at an elevation of 563 m to an upper reservoir at 850 m .
 When energy demand is high, the water is released back down towards the lower reservoir and fed through six 174.25 MW reversible Francis pump turbines, the same machines that pumped the water to the upper reservoir.
 The installed capacity of the power plant is 1,045 MW.
Pinjarra Power Station is a natural gas-fired power station in Western Australia.
 It is a 280 MW base load cogeneration power station located in Alcoa's Pinjarra Alumina Refinery, near the town of Pinjarra, approximately 80 km south of Perth, Western Australia.
 Generated electricity is sold by Alinta Energy to contracted customers or into the WA Wholesale Energy Market.
 In addition to electricity, the power station supplies steam to Alcoa's refinery.
The Heimifeng Pumped Storage Power Station () is located at the hills of Heimifeng, Qiaoyi town, Wangcheng district, 25 km north of Changsha in Hunan province, China.
 It was constructed between 2005 and 2009 with the generators being commissioned in 2009 and 2010.
 The station generates power by transferring water between an upper and lower reservoir.
 When energy demand is high, water from the upper reservoir is released and used to generate electricity before being discharged into the lower reservoir.
 During times of low demand, water from the lower reservoir is then pumped back up to replenish upper reservoir.
 This process allows the station to meet peak energy demand and it can go from standstill to operational in three minutes.
Alinta Energy is an Australian generation, electricity and gas retailing private company that is owned by Hong Kong-based Chow Tai Fook Enterprises.
 Alinta Energy has an owned and contracted generation portfolio of up to 1,957 MW, approximately 800,000 combined electricity and gas retail customers and around 450 employees across Australia and New Zealand.
