A fire at a National Grid site has shut down a power cable linking electricity supplies between the UK and France. A fire occurred in the early hours of Wednesday 15th September 2021 at our UK Sellindge site resulting in the cables capacity being reduced to 0MW. The onshore converter station will convert the electricity generated by the wind farm to 400 kV, before it enters the national grid. [12] [13] National Grid initially announced that half of the link capacity would be restored within a fortnight, with full capacity being restored in March 2022. Although each station includes an earth electrode, this is used only to provide a neutral reference, and only one of the two electrodes is connected at a given time so that there can be no current flow between them. 0000018925 00000 n 0000012629 00000 n You can also sign up to our website and comment on our stories by pressing here and signing in. 0000015608 00000 n 0000058162 00000 n The Sellindge converter station was built by GEC[6] and the Les Mandarins converter station was built by CGE Alstom. 49 0 obj <> endobj xref 49 54 0000000016 00000 n However, most HVDC converters are connected as twelve-pulse bridges. accelerate the energy transition.
