Concept notes

  • Pipeline laid in the consented Rampion 2 onshore cable trench between Climping landfall and the Bolney substation area, avoiding new corridor consenting.
  • High-level reservoir on Bignor Hill (~225 m AOD) provides gross head; an in-pipe Francis or Pelton turbine sits inland of the landfall.
  • Power export reuses the Rampion 2 onshore substation and existing 400 kV grid connection — no new grid infrastructure required.
  • All coordinates, distances and elevations are indicative for visualisation only; not based on Ordnance Survey vector data.
