Network Constraints

Constraint Details
  • Upstream constrained
  • Upgrade of 3 275/132kV SGTs required as per current Modification Application. Modification Application in progress to assess capacity at Iver 132kV Establish a new 132kV busbar and 132kV rated Denham BSP including 2 x 90MVA BSP transformers fed from Iver 132, this will shift the existing Denham Avenue and Gerrards Cross Primaries away from Denham 22kV (Jan 2029)
  • Moderate proximity to fault rating.
