Following the Stage 3 repair on subsea export cable 3 (SSEC3), Gwynt y Môr OFTO plc carried out system testing before returning the circuit to service. On 29 August 2024 senior authorised persons transferred control to the offshore substation, signed the GYM Equipment Acceptance Certificate and initiated a soak test of the repaired cable section, which ran for about 21.5 hours until 21:00 on 30 August 2024, after which the circuit was made available and re‑energised with a 90 MW export cap. Cable testing and associated jointing at the transition joint bay were completed as part of this testing phase.
