Parameter Compound dimensions


Maximum height of external electrical equipment (e.g. lightning rods)


Height of proposed mounds (from East Anglia ONE)


Heights of tree growth (from East Anglia ONE)


Orientation of buildings HGV Traffic movements 10m Approximately5m above ground level


Approximately 300mmper year following planting


The electrical conversion process and its relationship to the National Grid substation define orientation of the buildings.


Peak daily two-way HGV movements 26 HVDC


Phase IIa and Phase IIb Consultation Single Phase 1200MW (Scenario 1, 2014)


Phase III Consultation


Single-Phased 1200MW solution.


15m No change No change No change No change
