Pembroke Power Station
Encyclopedia
Pembroke B Power Station is a 2,000 MWe natural gas
-fired power station currently under construction near Pembroke
in Wales
. The new power station is being built on the site of the former oil-fired power station which closed in 1997 and demolished in 2000.
It will be a CCGT
-type power station that uses natural gas. Gas will come from the liquefied natural gas
(LNG) terminal at Milford Haven
and not directly from a gas field. There will be five 400 MW modules, each with a 288 MWe Alstom
gas turbine
, heat recovery steam generator and steam turbine
. It is expected to be fully operational by the end of 2012.
2,000 MW oil-fired power station
on the site from 1968 until 1996, when it was mothballed by National Power. In 1996, the company proposed to use the controversial fuel Orimulsion
but changed its mind in September 1997. National Power put the site up for sale in July 2000, and it was demolished from 2000 to 2003. National Power first proposed a CCGT power plant on the site in 1997, and this plan lasted until the price of electricity plummeted five years later. The German company, RWE
(former National Power
), decided in 2007 to build a £800 million power station on the site, after initially cancelling the plan when it chose Staythorpe
instead. The construction will be the largest power station built in the UK since Drax was completed in 1986, and will provide enough power for 3 million homes. The EPC
contractor is Alstom. Construction began in 2008 and will last until 2012, and it will employ around one hundred people. The old power station employed around 300 people.
