CENTRICA, which owns Scottish Gas, has said the development of the giant Cygnus gas field off eastern England will generate £323 million for the Scottish economy and secure 1,450 jobs in the country.

The utility said the estimate, based on research by Oxford Economics, highlighted the contribution the project will make during its five-year construction period.

Oxford Economics reckons the project will add £1.29 billion to the UK economy and support more than 4,820 skilled jobs during the construction phase.

Research by the consultancy found 19,000 tonnes of offshore infrastructure will be built at yards in Fife, the Highlands and Hartepool to produce gas from the field, which is operated by GDF Suez.

One platform and the bases for all four platforms are being built by Burntisland Fabrication at facilities in Methil and Burntisland in Fife and Arnish on the Isle of Lewis.

Colette Cohen, senior vice-president for the UK and the Netherlands at Centrica Energy, said: "This report underlines how significant an impact the Cygnus project is having across the UK both in terms of investment and jobs, as well as strengthening our security of gas supply."

Centrica, which has a 48.75% stake in Cygnus, said the field will produce enough gas to meet the demand of 1.5 million UK homes.

GDF Suez expects production to peak in 2016. The French utility has a 38.75% interest in Cygnus. Germany's Bayerngas has 12.5%.
