How will the power be transferred to the national grid, underground or via pylons?
The substation will be located within the Installation boundary, from where cabling will run underground to the base of the quarry void (circa 104m in length), prior to overhead cable (circa 74m in length) to the existing electricity pylon as shown on the drawing below. The substation is shown as the purple block. Underground cabling is the dashed purple line, above ground is solid purple. The nominal voltage is 33kV. No new pylons are proposed.
