A new 400 kV double circuit between Blackhillock and Peterhead |
Type: Develop new circuits
Status: Planning/consenting
Boundaries: B1aE; B1aF; B1aI; B2E; B2F; B2I; B4E; B4F; B4I
Region: Scotland |
Establish a new 400 kV double circuit overhead line from Blackhillock to Peterhead via New Deer. Peterhead and Blackhillock substations will require extension to accomodate termination of the new double circuit. This reinforcement is required as onshore works to faciliate the 2nd Eastern HVDC Link from Peterhead (NOA option reference E4L5)

NOA 2021/22 Refresh Recommendation: HND essential option |
BPRE
Reconductor the newly formed second Bramford to Braintree to Rayleigh Main circuit |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: EC5E; EC5I
Region: East England |
Replace the conductors of the newly formed Bramford to Braintree to Rayleigh Main circuit that have not already been reconductored with higher-rated conductors. Replace the conductors on the newly formed Bramford to Twinstead Green to Pelham circuit (Twinstead Tee to Pelham) with higher-rated conductors. This would increase the circuit's thermal rating following the new 400 kV double circuit between Bramford and Twinstead

BRRE
Reconductor remainder of Bramford to Braintree to Rayleigh route |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: EC5E; EC5I; LE1; SC1Rev
Region: |
Replace the conductors in the limiting sections of the existing Bramford to Braintree to Bulls Lodge and Bulls Lodge to Rayleigh Main overhead line that have not already been reconductored with higher-rated conductors, to increase the circuits overall thermal rating.

BTNO
A new 400 kV double circuit between Bramford and Twinstead |
Type: Develop new circuits
Status: Planning/consenting
Boundaries: EC5E; EC5I; LE1; SC1Rev
Region: East England |
Construct a new 400 kV double circuit between Bramford substation and Twinstead tee point to create double circuits that run between Bramford to Pelham and Bramford to Braintree to Rayleigh Main. Construct a new Grid Supply Point at Twinstead Green to allow UKPN's 132kV overhead line to be decomissioned and removed to allow space for the new overhad line. Construct four new shunt reactors, two at Bramford substation and two at Rayleigh substation. It would increase power export capability from East Anglia into the rest of the transmission system.

BTR2
Upgrade the existing circuits between Brinsworth and Thorpe Marsh to allow for more capacity |
Type: Upgrade existing circuits
Status: Scoping
Boundaries: B8;
Region: North England |
This project is also currently required to enable the development of a robust and reliable offshore network connection and will be reappraised in the detailed design stage
|
NOA 2021/22 Refresh Recommendation: Hold |
BWRE
Reconductor Barking to West Ham double circuit |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: LE1
Region: South Wales and South England |
Replace the conductors in the Barking to West Ham single circuit with higher-rated conductors.
|
NOA 2021/22 Refresh Recommendation: Hold |
CDHW
Cellarhead to Drakelow circuits thermal uprating |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: B7aE; B7aI; B8
Region: North Wales and West Midlands |
Thermal upgrade of both Cellarhead to Drakelow 400 kV circuits to allow them to operate at higher temperature and rating.
|
NOA 2021/22 Refresh Recommendation: Proceed - Critical |
CDP1
Power control device along Cellarhead to Drakelow |
Type: Control power flow
Status: Strategic Optioneering
Boundaries: B8
Region: North Wales and West Midlands |
Install a power control device along the Cellarhead to Drakelow 400 kV overhead line route. This would improve the capability to control the power flows from north to south of the transmission network.

CDP3
Additional alternative power control devices along Cellarhead to Drakelow |
Type: Control power flow
Status: Strategic Optioneering
Boundaries: B7aE; B7aI; B8
Region: North Wales and West Midlands |
Install additional alternative power control devices along the Cellarhead to Drakelow 400 kV overhead line route. This would improve the capability to control the power flows from north to south of the transmission network.
