French energy regulator CRE has given the go-ahead for a second interconnector with Great Britain.

The “IFA2” electricity cable will link Chilling near Southampton to Tourbe near Caen.

The 1GW interconnector is expected to cost €750 million (£640m).

The new cable is expected to begin operating in 2020.

Unaffected by Brexit

CRE said: “The various promoters believe that the economic fundamentals of the projects remain the same whether the UK is in the European Union or not, and the consequences of Brexit on the project remain very limited.”

French grid operator RTE, which is developing the link with National Grid, will take its final investment decision before the end of 2018.

Great Britain and France are already linked by the 2GW IFA interconnector, which began operating in 1986.
