TWNC
New circuit between Wymondley and Waltham Cross and increase operating voltage of the network within the area |
Type: Develop new circuits
Status: Scoping
Boundaries: B9; LE1;
Region: South Wales and South England |
To upgrade Wymondley, Waltham Cross and Tilbury from 275 kV to 400 kV, create new double circuit from Wymondley to Waltham Cross, and upgrade Waltham Cross to Tilbury 275 kV route to 400 kV. This would help move flow west to east during periods of interconnector export on the south coast coincident with high wind output further north.
