The first HVDC bipole outage was carried out on 18 January as planned. We are currently in a 2 week period until 1 Feb where the HVDC is in monopole (Pole 3 only) and the HVDC electrode is on an outage. The next HVDC bipole outage is scheduled for 1 February. We have previously carried out analysis for this period which can be found on our website here. We do not currently foresee any risk to security of supply.
