28 Jan 2021: From 13th July 2020 until 31th July 2020 there was a reduction in export cable transmission as Gwynt y Môr OFTO plc undertook a pre-emptive repair of the cable sealing ends (CSE). Independent technical analysis determined that the root cause of the event was the result of low oil pressure and leakage caused by a failure of the tape within the terminations of the CSEs and a flat on the O ring within the CSE. Gwynt y Môr OFTO plc submitted an Exceptional Event claim to Ofgem on 23rd September 2020. Gwynt y Môr OFTO plc claim that there was "no routine maintenance intervention that the OFTO could have undertaken to avoid this event occurring". On 28th January 2021 Ofgem approved the Exceptional Event claim. Given the technical analysis and explanation provided, Ofgem agree that routine maintenance could not have prevented such faults and is satisfied that the root cause of this event did in fact occur before asset transfer and was beyond the reasonable control of Gwynt y Môr OFTO plc.
