Question: Who operate the power station whose part was replaced by Barker Inlet Power Station?

full_context: Document 1: Barker Inlet: The Barker Inlet is a tidal inlet of the Gulf St Vincent in Adelaide, South Australia, named after Captain Collet Barker who first sighted it in 1831. It contains one of the southernmost mangrove forests in the world, a dolphin sanctuary, seagrass meadows and is an important fish and shellfish breeding ground. The inlet separates Torrens Island and Garden Island from the mainland to the East and is characterized by a network of tidal creeks, artificially deepened channels, and wide mudflats. The extensive belt of mangroves are bordered by samphire saltmarsh flats and low-lying sand dunes, there are two boardwalks (at Garden Island and St Kilda), and ships graveyards in Broad Creek, Angas Inlet and the North Arm.
Document 2: Torrens Island Conservation Park: Torrens Island Conservation Park is a protected area located on Torrens Island in South Australia about 3.9 km north-northeast of Port Adelaide. The conservation park covers the majority of Torrens Island down to low water with exception to the land associated with the former quarantine station and the Torrens Island Power Station. The east side of the conservation park immediately adjoins the Barker Inlet-St Kilda Aquatic Reserve. The conservation park is reported as protecting ‘areas of mangrove forest, samphire shrubland and sand dune systems home to vulnerable and threatened species such as the Australasian bittern, the fairy tern and the white-bellied sea eagle’. The conservation park is classified as an IUCN Category III protected area.
Document 3: Barker Inlet Power Station: Barker Inlet Power Station is a proposed power station in South Australia. It was announced on 7 June 2017 by AGL Energy to replace part of its aging Torrens Island Power Station and would be built alongside the existing station on Torrens Island in the northwestern suburbs of Adelaide. Construction was expected to start in the third quarter of 2017, with commissioning in the first quarter of 2019.
Document 4: Teesside power station: Teesside Power Station is a former gas-fired power station, in Redcar & Cleveland, England. Situated near the Wilton chemical complex, the station had combined cycle gas turbines (CCGTs) and open cycle gas turbines (OCGTs), however in 2011 the operation of the CCGT part of the station was suspended, and in 2013 the owners announced its closure and plans to demolish it. Prior to the suspension, the station had a generating capacity of 1875 megawatts (MW), making it the largest of any CCGT power station in Europe. The station could meet almost 3% of the electricity demand for England, Wales and Scotland. Opened in 1993, the station was initially operated by Enron, but after the Enron scandal of 2001, when the station moved into the hands of PX Ltd, before being bought by Gaz de France and Suez in 2008. The station also worked as a cogeneration plant, providing steam for the Wilton complex.
Document 5: Warrick Power Plant: Warrick Generating Station is a 755-MWe coal-fired electricity-generating station, located southeast of Newburgh in Warrick County. It sits on the north bank of Ohio River, downstream of the F. B. Culley Generating Station. The plant has four coal-fired, steam-powered turbines with a combined generating capacity of 791 MWe. Alcoa owns three of the four generating stations, which were placed into service in the early 1960s. The largest unit, known as Unit 4, is 323-MWe unit jointly owned by Alcoa and Vectren. This larger unit was placed in operation in 1970.
Document 6: Battersea Power Station: Battersea Power Station is a decommissioned coal-fired power station located on the south bank of the River Thames, in Nine Elms, Battersea, an inner-city district of South West London. It comprises two individual power stations, built in two stages in the form of a single building. Battersea A Power Station was built in the 1930s, with Battersea B Power Station to the east in the 1950s. The two stations were built to a nearly identical design, providing the long-recognized four-chimney layout. The station ceased generating electricity in 1983, but over the past 50 years it has become one of the best known landmarks in London and is Grade II* listed. The station's celebrity owes much to numerous popular culture references, which include the cover art of Pink Floyd's 1977 album "Animals" and its appearance in the 1965 Beatles' film "Help!"
Document 7: Torrens Island Power Station: Torrens Island Power Station is located on Torrens Island, near Adelaide, South Australia and is operated by AGL Energy. It burns natural gas in eight steam turbines to generate up to 1,280 MW of electricity. The gas is supplied via the SEAGas pipeline from Victoria, and the Moomba Adelaide Pipeline System (MAPS) from Moomba in the Cooper Basin. The station is capable of burning either natural gas or fuel oil. It is the largest power station in South Australia and was formerly the largest single power station user of natural gas in Australia.
Document 8: Barry Power Station: Barry Power Station is a 230MWe gas-fired power station on "Sully Moors Road" in Sully in the Vale of Glamorgan, Wales. It is eight miles west of Cardiff and is next to a large Ineos Vinyls chemicals works that makes PVC and a Hexion Chemicals plant.
Document 9: 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.
Document 10: Bayswater Power Station: Bayswater Power Station is a bituminous (black) coal-powered thermal power station with four 660 MW Tokyo Shibaura Electric (Japan) steam driven turbo alternators for a combined capacity of 2,640 MW . Commissioned between 1985 and 1986, the station is located 16 km from Muswellbrook, and 28 km from Singleton in the Hunter Region of New South Wales, Australia.
Document 11: Quarantine Power Station: Quarantine Power Station is a gas-powered electricity generation facility near the northern end of Torrens Island in the northwestern suburbs of Adelaide, South Australia. It is at the opposite end of Torrens Island from AGL Energy's Torrens Island and Barker Inlet power stations. It gets its name from the Torrens Island Quarantine Station which was nearby.
Document 12: Dunston Power Station: Dunston Power Station refers to a pair of adjacent coal-fired power stations in the North East of England, now demolished. They were built on the south bank of the River Tyne, in the western outskirts of Dunston in Gateshead. The two stations were built on a site which is now occupied by the MetroCentre. The first power station built on the site was known as Dunston A Power Station, and the second, which gradually replaced it between 1933 and 1950, was known as Dunston B Power Station. The A Station was, in its time, one of the largest in the country, and as well as burning coal had early open cycle gas turbine units. The B Station was the first of a new power station design, and stood as a landmark in the Tyne for over 50 years. From the A Station's opening in 1910 until the B Station's demolition in 1986, they collectively operated from the early days of electricity generation in the United Kingdom, through the industry's nationalisation, and until a decade before its privatisation.
Document 13: Tarong North Power Station: 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.
Document 14: Aberthaw power stations: Aberthaw Power Station is a series of two coal-fired power stations on the coast of South Wales, near Barry in the Vale of Glamorgan. It is located at Limpert Bay, near the villages of Gileston and West Aberthaw. The current power station on the site, Aberthaw B Power Station, co-fires biomass and as of 2008 has a generating capacity of 1560 megawatts (MW).
Document 15: Reeves Plains Power Station: Reeves Plains Power Station is a proposal from Alinta Energy to build a gas-fired power station at Reeves Plains between Gawler and Mallala in South Australia. The proposed site borders both the Moomba-Adelaide gas pipe and an electricity transmission line. The power station is proposed to use six gas turbines to produce up to 300 MW of electricity. It is expected to be operated at a peaking plant rather than running full time. The primary source of fuel will be the gas pipeline, however the plant will also be able to operate on diesel fuel, and will have diesel storage on site. Stage 1 is expected to only be two or three of the turbines, generating 100 to 150 MW of electricity. The power station is expected to take 12 months to build, and be commissioned in January 2019.
