It comes as the UK has been hit with record energy prices after a global gas market surge raised the cost of running gas power plants, which has been compounded by a string of outages and low wind speeds. Whilst repairs were undertaken there was considerable down time on the circuit resulting in a loss of trading. The blaze at the Sellindge converter station in Kent forced a shutdown of the high-voltage cable that brings electricity from France to the UK last month as energy markets rocketed to all-time. The continued size and duration of the flows are open to some doubt, given the growth in demand in continental Europe for clean electricity, and increasing electricity demand within France.[17]. s{\e5a`XXb6Nn=3LUk+2=_Z*b3WE{Z4k 6t^UxYlaM In order to return the site safely to service, the Grid says that "extensive work" must be carried out. Cables are laid in pairs in four trenches so that the magnetic fields generated by the two conductors are largely cancelled.
