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. HistoryConstruction began in January 1997 and it was opened on 7 September 1998, being owned by the AES Corporation but trading as AES Barry Ltd. Until 2000 it ran as a base load station. It was bought by Centrica on 24 July 2003 for £39.7m. AES sold the plant because of the low price of electricity at that time. The closure of the plant was proposed in Centrica's accounts in February 2012, but the following month a contract was signed to use it to supply peak power.[1] This required a reconfiguration to allow full load to be reached more quickly, and redundancy for a third of the workforce.[1] It is now run in an open-cycle mode, halving operating costs, with the option of switching to combined-cycle mode after an hour.[2] SpecificationIt is a CCGT-type power station. There is one 160 MWe Siemens [https://web.archive.org/web/20080918095214/http://www.ansaldoenergia.com/GasTurbines_Features.htm V94.2] gas turbine (built by Ansaldo Energia in Genoa and now called the SGT5-2000E) that feeds exhaust gas at 544 °C to a heat recovery steam generator. Steam from this enters a 75 MWe steam turbine running, like the gas turbine, at 3000 rpm. Exhaust steam is passed through an air-cooled condenser and returned to the system as de-aerated feedwater for the HRSG. It connects to the Western Power Distribution section of the National Grid via a substation at 132 kV. The generator on the gas turbine is rated at 180 MVA and has a terminal voltage of 15 kV; the steam turbine's is 11 kV. The plant is 44% thermally efficient. The chimney is 60 m high.
