Fawley Power Station was an oil-fired power station located on the western side of Southampton Water, between the villages of Fawley and Calshot in Hampshire, England. Its 198-metre (650 ft) chimney was a prominent (and navigationally useful) landmark, but it was not, as is sometimes claimed, the highest point in Hampshire (which is Pilot Hill).

Overview

The station, which in its final years was owned and operated by Npower, was oil-fired, powered by heavy fuel oil. Pipelines connected the station to the nearby Fawley oil refinery. There were two 10-inch (25 cm) diameter, 3.2-kilometre (2.0 mi) long, pipelines which discharged into storage tanks with a capacity of 24,000 tonnes.[3] Due to oil being more expensive than other fuels such as coal and natural gas, Fawley did not operate continuously, but came on line at times of high demand.

It was also connected to the National Grid with circuits going to Nursling and a tunnel under Southampton Water to Chilling then to Lovedean with a local substation at Botley Wood.

A dock was included in the construction, to allow for the delivery of oil by sea; however, after one ship delivery (essentially a trial) this facility remained disused.

History

Fawley was built by

CEGB between 1965[5] and 1969.[6] It was commissioned in 1971 as a 2,000-megawatt
(MW) power station, with four 500 MW generating units, each consisting of a boiler supplying steam to a turbine that powers an associated generator.

The boilers were capable of delivering 1,788.0 kg/s of steam at 158.6 bar and 538 °C.[7] The cooling pumps were Britain's largest with a flow of 210,000 GPM. One was driven by an experimental super-conducting electric motor.

In 1978/79 Fawley was presented with the Hinton Cup, the

CEGB's "good house keeping trophy". The award was commissioned by Sir Christopher Hinton, the first chairman of the C.E.G.B. It was the first time that a C.E.G.B region (South West) had won both the Hinton Trophy and Hinton Cup. The cup going to the Solent transmission district.[8]
