Repairs to the anchor-damaged UK-France interconnector will be complete at the end of March, at a cost of £30-40m, according to French grid operator RTE.

The UK’s biggest energy interconnector was damaged by Storm Angus in November.

The National Grid had confirmed that the Interconnexion France-Angleterre (IFA) interconnector with France was to run at 50 per cent of its capacity initially until the end of February after investigations revealed four of its eight subsea cable were severed during the storm.

“We experienced a trip of the IFA interconnector on the morning of Sunday 20 November,” National Grid said in a statement. “After further investigation, the fault has been identified and we can confirm that four of IFA’s eight cables have been damaged. This will result in a reduction of IFA’s maximum capacity to 1000MW until the end of February 2017.
