Latest event on Rampion

Similar damage was identified within the western cable as that found in the eastern marine export cable. As this will compromise its performance, E.ON plan to replace this cable which runs between the offshore substation and landfall at Brooklands, during the summer. The project remains on schedule to be complete and fully operational later this year. Read more

Project Details for Rampion
General Information Name Rampion correct
Other names Hastings, Zone 6 correct
Country name United Kingdom correct
Region England, South East correct
Comments The maximum number of turbines was reduced from 195 to mitigate visual impacts.

E.ON has opted for "Generator Build" option for the offshore transmission assets. E.ON will employ a multicontract approach rather than turnkey/EPC. Approx 20 ‘main’ Tier 1 contracts, but in practice could be 200+ other ancillary contracts over course of the project construction and operation.

July 2014 The Crown Estate invited all Round 3 developers to revise the terms of their agreement as the projects transition from zone appraisals to project development. This could mean that zone development agreements are replaced with project specific contractural agreements.

Rampion will be part of Ofgem's Tender Round 5, expected to launch later in 2016, with regards to the sale of its offshore transmission assets once constructed.
