National Grid restored IFA1 to full commercial service (the full 2 GW capacity) on 27 January 2023 following the rebuild and commissioning work to recover equipment damaged by the 2021 converter‑hall fire. The return to full service reinstated the interconnector’s full transmission capability between Sellindge (GB) and Les Mandarins (FR), increasing overall GB interconnector capacity.
