AENC
A new 400 kV double circuit in north East Anglia |
Type: Develop new circuits
Status: Design/development and consenting
Boundaries: EC5E; EC5I; LE1; SC1Rev
Region: East England |
Construct a new 400 kV double circuit in north East Anglia to facilitate power transfer requirements across the relevant boundaries. Substation works are required to accommodate the new circuits.

NOA 2021/22 Refresh Recommendation: HND essential option |
ATNC
A new 400 kV double circuit in south East Anglia |
Type: Develop new circuits
Status: Design/development and consenting
Boundaries: EC5E; EC5I; LE1; SC1Rev
Region: East England |
Construct a new 400 kV double circuit in south East Anglia to facilitate power transfer requirements across the relevant boundaries. Substation works are required to accommodate the new circuits, including a new substation to facilitate customer connections.

NOA 2021/22 Refresh Recommendation: HND essential option |
BBNC
Beauly to Blackhillock 400 kV double circuit addition |
Type: Develop new circuits
Status: Planning/consenting
Boundaries: B1aF; B2F; B4F;
Region: Scotland |
Construct a new 400 kV double circuit between Beauly and Blackhillock. At both sites extend the 400 kV busbar arrangements to allow for the connection of two additional bays.

BDUP
Uprate the Beauly to Denny 275 kV circuit to 400 kV |
Type: Voltage and stability constraints
Status: Planning/consenting
Boundaries: B1aE; B1aF; B1aI; B2E; B2F; B2I; B4E; B4F; B4I; B5; B6SPT
Region: Scotland |
Uprating of the 275 kV side of the existing Beauly-Denny circuit to 400 kV operation between SHE Transmission and SPT. Substation works will be required at Beauly, Fasnakyle, Fort Augustus, Kinardochy, Braco West and Denny North. The Errochty I/T scheme (implemented under ECU2) shall be amended to trip the 400/132 kV supergrid transformer (SGTs) at Kinardochy under loss of the 400 kV double circuit south of Kinardochy.
