Nautilus project materials from National Grid Ventures and National Grid ESO describe that ESO completed an appraisal of Nautilus’s grid connection request and identified the Leiston / Sizewell area in East Suffolk as the preferred connection zone. By 2020–2021, National Grid documentation refers to Nautilus already having a connection agreement in the Leiston area, which indicates that the ESO appraisal and offer acceptance were concluded earlier. Considering the CEF 2019 PCI action for Nautilus early‑stage development and the presence of an agreed connection location by 2020–2021, it is reasonable to place the ESO grid offer appraisal and acceptance around 2019.
