Constraint Details

Upstream constrained
Subject to Mod App outcome Reinforce the 33kV circuit between Chippenham BSP and Yatton Keynell (Mar 2027) Replace the 33kV switchgear at Chippenham BSP (Aug 2027) Reinforce the 132kV circuits between Melksham GSP and Chippenham (Aug 2027) Add a 3rd 90MVA BSP transformer at Chippenham (Oct 2027) Add a new 33kV circuit between Yatton Keynell and Alterton (Jun 2028)
Distribution constrained
Replace the existing transformers with 7.5MVA units
Constrained due to upstream thermal limitations on Chippenham BSP TX under N-1
Upstream queue: 515.5MW
