3.3 Onshore 35.


There are a number of key changes which may affect onshore receptors. The cable ducts being installed during the construction of East Anglia ONE removes the need for HDD or open trenching and substantially limits the amount of construction work necessary and the associated levels of disruption. The potential implications of this are set out within section 2.2 of this report.


36. As a result of the feedback from the local community and local authorities and consideration of constraints, the number of accesses has been refined down from 59 to 38.


37.


With either the Single Phase or Two Phased approach the number of jointing bays is reduced to one per pair of ducts. This reduces the number of pits required (as previously there was one pit per duct per location), however changes in the design of the jointing pits mean that there will be more material required overall with either electrical solution. In addition the number of kiosks (by which the cable joints are accessed) is increased from 122 to 248. See Tables 2.2 and 2.3 for a summary of the differences in infrastructure required when compared to the PEIR.


38.


With either the Single Phase or Two Phased approach the size of the substation compound increases slightly; to 2.85ha for the HVDC solution and 3.04ha for the LFAC solution.
