King's Lynn Power Station refers to acombined cycle natural gas power station nearKing's Lynn inNorfolk, commissioned in 1997, and now owned by RWE, and to a coal fired power in King's Lynn in operation from 1899 to 1960. The CCGT station was mothballed on 1 April 2012. It can generate 325 MW of electricity and employed 40 people. The site was reopened on 19 November 2019.[1]
Construction of this power station began in October 1994 and was completed and started producing electricity in December 1997.[2] The owners of the plant,TXU sold the plant toCentrica in October 2001.
The plant was mothballed on 1 April 2012 as older, less efficient, plants such as King's Lynn had become uneconomic due to high gas prices.[3]
In December 2019 RWE purchased the plant from Centrica. The plant joins the UK gas portfolio which is the largest and most efficient fleet in the UK.[4]
TheCombined cycle gas turbine power station is located on Willows Business Park, Saddlebow, King's Lynn and uses gas fromNational Grid's National Transmission System.
The station was built with one single shaft 237 MWSiemens V94.3Gas driven Turbine with electricalgenerator running at 3,000 rpm. The terminal voltage is 21 kV. There is a vertical type triple pressureheat recovery steam generator designed by CMI SA (Belgium)and supplied by CMI SA andInternational Combustion (since 1997 known asABB Combustion Services Ltd. The plant has onesteam turbine that is coupled to the generator via a self synchronizingclutch. The plant was built with one air cooledcondenser which compromises of 61 cooling modules of fins, tubes and fan arranged in four by four configuration, connected to the 132 kV electrical distribution system. The original output of the station was 325 MWe. The power station employs around forty-one staff.
In 2006 it generated 900 GWh and emitted the following pollutants:-[2]
Centrica has an option to build about 1,000 MW of gas generation capacity near the present site, but has yet to decide if this will go ahead.[3][5] In 2013National Grid obtained consent to build a new 400 kV grid connection, but a decision on proceeding is awaited.[6][7]
King’s Lynn power station also refers to a small 5 MW coal fired power station in Kettlewell Lane in the town centre which operated from 1899 to 1960.
The King’s Lynn Corporation had been granted a Provisional Order under the Electricity Acts to supply electricity to the town in 1896. Supplies of electricity started on 19 August 1899.[8]
By 1921 the plant at the station comprised a 1 MWsteam turbine plus two 200 kW and one 400 kW reciprocating engine generators. The station supplied 3-phase 50 Hz AC at 230 and 400 Volts, and 200 and 400 Volt DC.[9] By 1959 the plant comprised one 2.5 MW, one 1.5 MW and one 1.25 MWturbo-alternator sets. Only alternating current was supplied. The station drew its cooling water from the River Gaywood.[10]
The electricity supplied by the station was:[11][8][9][10]
