Constraint Details
  • Upstream constrained
  • Alton & Fernhurst BSP group to be split (Sept 2025) Replace the AIS switchboad at Alton with a GIS switchboard (Jun 2028) A new 132kV switching station is to be established between Fleet GSP, Alton BSP and Fernhurst BSP to supply Alton and Fernhurst from Nursling under N-2 conditions (Aug 2028) Fleet & Bramley GSP group to be split and a new 132kV switchboard installed at Bramley (Jul 2030)
  • Limited flexible headroom on the 132 kV circuits from Fleet. Fleet GSP 132kV switchgear saturated for fault level capacity. 132kV fault level reinforcement required at Fleet GSP
Upstream TX Queue N/A
contracted generationat upstream GSP

High queue indicates significant generation already contracted at this connection point.
