Question: Who owns the power station for which the Myuna Colliery was developed to provide coal  ?
Context: Tarong North Power Station is a 443 megawatt coal fired power station on the same site as Tarong Power Station in the South Burnett.  The Queensland Government commissioned the construction of the power station in November 1999.  Construction work began in 2000.  The power station was initially owned by a 50/50 joint venture between Tarong Energy and TM Energy.  Full ownership of the power station by Tarong Energy was obtained in November 2009. 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. Lamma Power Station (), informally known as Lamma Island Power Station, is a coal and gas-fired power station in Po Lo Tsui, Lamma Island, Islands District, Hong Kong.  With the installed capacity of 3,736 MW, the power station is the second largest coal-fired power station in Hong Kong after Castle Peak Power Station. Chain Valley Colliery is a coal mine located at Mannering Park, New South Wales, Australia.  The colliery was developed to provide coal for the Vales Point Power Station, adjacent to the mine.  The mine started in August 1960, with coal production commencing in 1961.  The Great Northern and Fassifern coal seams have been mined using bord and pillar mining methods.  Coal is transported to the Vales Power Station by an overland conveyor system, while excess coal is trucked to domestic customers and also to the Port of Newcastle for export. The Morupule Colliery is a coal mine located in Palapye, Botswana, and owned and operated by Debswana, a partnership between the government of Botswana and De Beers.  Founded in 1973 to supply the Bamangwato Concessions, Ltd copper and nickel mine, operations have expanded considerably since then to supply regional power plants and industries, especially the nearby Morupule Power Station.  A small wash plant, with a production capability of 120 tonnes per hour, was commissioned in January 2008 to supply a higher quality coal to local and regional consumers.  This project was supported by the Botswana government as a means of stimulating the local economy, producing a less polluting form of coal than the run-of-mine coal, and to provide an alternative to the unsustainable use of wood for cooking and heating. 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. Westside Mine is a coal mine located at Wakefield, New South Wales, Australia.  The open cut mine was developed to provide coal for the Eraring Power Station.  The mine started in 1992.  The mine is proposed to be closed in 2012. Myuna Colliery is a coal mine at Wangi Wangi, New South Wales, Australia.  The colliery was developed to provide coal for the Eraring Power Station, 5 kilometres to the west.  The mine started in August 1979, with coal production commencing in 1982.  The Wallarah, Great Northern and Fassifern coal seams have been mined using bord and pillar mining methods.  Coal is transported to the Eraring Power Station by an overland conveyor system. 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. Eraring Power Station is a coal fired electricity power station with four 720 MW Toshiba steam driven turbo-alternators for a combined capacity of 2,880 MW.  The station is located near the township of Dora Creek, on the western shore of Lake Macquarie, New South Wales, Australia and is owned and operated by Origin Energy.  It is Australia's largest power station.
