Context paragraphs:
Cockburn Power Station: Cockburn Power Station (CKB) is a power station in Cockburn, Western Australia.  The station was commissioned in 2003.  It has a 160 MW natural gas powered gas turbine which provides steam to an 80 MW steam turbine that together generate a total 240 MW of electricity.

Condamine Power Station: Condamine Power Station is a 140 MW combined cycle power station near Miles on the western Darling Downs in Queensland, Australia.  The station is located 8 km east of Miles on the south side of the Warrego Highway.  The Condamine Power Station is owned by QGC Limited, a subsidiary of BG Group.  It has been claimed to be the world’s first combined-cycle power station entirely fired by untreated coal seam gas and Australia's first steam turbine condenser cooled by coal seam methane waste water.  However, the Townsville Power Station at Yabulu, which was converted from a peak load power station to burn only coal seam gas in a combined cycle configuration, was commissioned much earlier, in February 2005.

Lünen Power Station: Lünen Power Station is a coal-fired power station in Germany.  It's located in Lünen in the district Unna.  It has an output capacity of 500 megawatts.  The first power station in Lünen was commissioned in 1938.  The power station produces traction current since 1984 also.  The power station has also been producing long-distance heating since late 2003.  Annual coal consumption amounts to 960,000 tons.  The operator of the power station is Evonik Industries.  The power station's chimney is 250 m high.

Fengning Pumped Storage Power Station: The Fengning Pumped Storage Power Station is a pumped-storage hydroelectric power station currently under construction about 145 km northwest of Chengde in Fengning Manchu Autonomous County of Hebei Province, China.  Construction on the power station began in June 2013 and the first generator is expected to be commissioned in 2019, the last in 2021.  Project cost is US$1.87 billion.  On 1 April 2014 Gezhouba Group was awarded the main contract to build the power station.  It will be constructed in two 1,800 MW phases.  When complete, it will be the largest pumped-storage power station in the world with an installed capacity of 3,600 MW.  The power station will operate by shifting water between an upper and lower reservoir to generate electricity.  During periods of low energy demand, such as at night, water will be pumped from Fengning Lower Reservoir up to the upper reservoir.  When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity.  The process is repeated as necessary and the plant will serve as a peaking power plant.

Yixing Pumped Storage Power Station: The Yixing Pumped Storage Power Station is a pumped-storage hydroelectric power station located Yixing city of Jiangsu Province, China.  Construction on the power station began in 2003 and the first unit was commissioned in 2007, the last in 2008.  The entire project cost US$490 million, of which US$145 million was provided by the World Bank.  The power station operates by shifting water between an upper and lower reservoir to generate electricity.  The lower reservoir was formed with the existing Huiwu Dam at the foot of Mount Tongguan.  The Yixing Upper Reservoir is located atop Mount Tongguan which peaks at 530 m above sea level.  During periods of low energy demand, such as at night, water is pumped from Huiwu Lower Reservoir up to the upper reservoir.  When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity.  Water from the nearby Huangtong River can also be pumped into the lower reservoir to augment storage.  The process is repeated as necessary and the plant serves as a peaking power plant.  The power station is operated by East China Yixing Pumped Storage Co Ltd.

Mettur Thermal Power Station: The Mettur Thermal Power Station is a coal-fired electric power station located in Salem district of Tamil Nadu.  It is operated by Tamil Nadu Generation and Distribution Corporation Limited.  The power station was commissioned during various periods from 1987 and this is the first inland thermal Power Station of TANGEDCO. The coal from Mahanadi Coalfields Limited (Talcher and Ib Valley) and Eastern Coalfields Limited (Raniganj and Mugma) are transported to the load ports of Paradip (Orissa), Vizag (Andhra Pradesh) and Haldia (West Bengal).  Thereafter the coal is transported to the discharge ports of Ennore and Tuticorin by ships.  From Ennore Port the coal is transported again through rail to Ennore Thermal Power Station and Mettur Thermal Power Station.

Barron Gorge Hydroelectric Power Station: The Barron Gorge Hydroelectric Power Station (or Barron Gorge Hydro) in Queensland, Australia is an electricity power station commissioned in 1963 with a maximum capacity of 66 MW .  It is located in the Wet Tropics World Heritage Area 20 km north-west of Cairns.  It replaced an earlier station which was the first underground power station in the country and the first hydroelectric station in Queensland.  The power station was refurbished in 2006.

Jablanica Dam: The Jablanica Dam is an arch-gravity dam on the Neretva River about 4 km northeast of Jablanica in the Herzegovina-Neretva Canton of Bosnia and Herzegovina.  The dam was constructed between 1947 and 1955 with the primary purpose of hydroelectric power production.  The power station was commissioned in two stages, from 1955 until 1958.  The first generator was commissioned in February 1955.  An upgrade in 2008 increased the installed capacity of the power station from 150 MW to 180 MW.  The dam's power station is located about 4.4 km to the southeast near Jablanica and discharges back into the Neretva River.  It contains six 30 MW Francis turbine-generators for an installed capacity of 180 MW.  The difference in elevation between the reservoir and power station afford a hydraulic head (water drop) of 111 m .  The dam is 85 m tall and creates Jablanica lake.  The dam and power station are owned and operated by Elektroprivreda Bosne i Hercegovine.

Western Australia: Western Australia (abbreviated as WA ) is a state occupying the entire western third of Australia.  It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Southern Ocean to the south, the Northern Territory to the north-east and South Australia to the south-east.  Western Australia is Australia's largest state with a total land area of 2,529,875 square kilometres (976,790 sq mi), and the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic – however, a significant part of it is sparsely populated.  The state has about 2.6 million inhabitants, around 11% of the national total.  Ninety-two per cent of the population lives in the south-west corner of the state.

Uthuru Janani Power Station: The Uthuru Janani Power Station (also sometimes called the New Chunnakam Power Station, as it is the successor of the former Chunnakam Power Station) is a 24-megawatt thermal power station commissioned on 1 January 2013, in Chunnakam, Sri Lanka.  The power station consists of three diesel-run generating units with a capacity of 8 MW each, producing 176 GWh annually.  Built and operated by the Ceylon Electricity Board for Rs.  3.5 billion , the power station costs Rs. 17.86 to generate one unit (1 KWh) of electricity.
