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.
History
Construction began in January 1997, and it was opened on September 7, 1998, being owned by the AES Corporation, but trading as AES Barry Ltd. Until 2000, it ran as a baseload station. It was bought by Centrica on July 24, 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]
Specification
It is a CCGT-type power station. There is one 160 MWe Siemens V94.2 gas turbine (built by Ansaldo Energia in Genoa and now called the SGT5-2000E) that feeds exhaust gas at 544C to a heat recovery steam generator. Steam from this enters a 75MWe 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 132kV. The generator on the gas turbine is rated at 180MVA and has a terminal voltage of 15kV; the steam turbine's is 11kV.
The plant is 44% thermally efficient. The chimney is 60m high.
