LWUP
Kincardine 400 kV reinforcement |
Type: Voltage and stability constraints
Status: Design/development and consenting
Boundaries: B1aE; B1aF; B1aI; B2E; B2F; B2I; B4E; B4F; B4I; B5; B6SPT
Region: Scotland |
Establish a new 400kV substation north of Kincardine and connect to Denny North at 400kV, integrating load and non-load related investment drivers and enabling significant reinforcement of transfer capacity through central Scotland.

NOA 2021/22 Refresh Recommendation: Proceed - Critical |
MBHW
Bramley to Melksham circuits thermal uprating |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: B12a; B13; LE1; SC1.5Rev; SC1Rev
Region: South Wales and South England |
Thermal Upgrade of both Bramley to Melksham 400 kV circuits to allow them to operate at higher temperature and rating.
|
NOA 2021/22 Refresh Recommendation: Hold |
MBRE
Replace the conductors on the existing circuit between Bramley and Melksham with higher capacity conductors |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: B12a; B13; SC1Rev
Region: South Wales and South England |
NOA 2021/22 Refresh Recommendation: Hold |
|
MRP2
Additional power control devices at both Harker and Penwortham |
Type: Control power flow
Status: Construction
Boundaries: B6E; B6F
Region: North England |
Install additional power control devices at both Harker and Penwortham. This would improve the capability to control the power flow in both these areas of the transmission network.
|
NOA 2021/22 Refresh Recommendation: Proceed - Critical |
MRU1
Upgrade the existing Mersey ring of circuits and substations to allow for more capacity (Phase 1 of 2) |
Type: Upgrade existing circuits
Status: Scoping
Boundaries: B7a
Region: North England |
Upgrade the existing Mersey ring of circuits and substations to allow for more capacity (Phase 1 of 2)
|
NOA 2021/22 Refresh Recommendation: Hold |
MRU2
Upgrade the existing Mersey ring of circuits and substations to allow for more capacity (Phase 2 of 2) |
Type: Upgrade existing circuits
Status: Scoping
Boundaries: B7a
Region: North England |
Upgrade the existing Mersey ring of circuits and substations to allow for more capacity (Phase 2 of 2)
|
NOA 2021/22 Refresh Recommendation: Hold |
NBEU
Carry out thermal upgrading to Bramford and Norwich substations |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: EC5E; EC5I; SC1Rev
Region: East England |
NOA 2021/22 Refresh Recommendation: Hold |
|
NBRE
Reconductor Bramford to Norwich double circuit |
Type: Upgrade existing circuits
Status: Strategic Optioneering
Boundaries: EC5E; EC5I; LE1; SC1Rev
Region: East England |
The double circuit that runs from Norwich to Bramford would be reconductored with a higher-rated conductor.
|
NOA 2021/22 Refresh Recommendation: HND essential option |
NEMS
225 MVAr MSCs within the north east region |
Type: Voltage and stability constraints
Status: Strategic Optioneering
Boundaries: B7aE; B7aI
Region: North England |
Three new 225 MVAr switched capacitors (MSCs) at Norton, Osbaldwick and Stella West 400 kV substations would provide voltage support to the east side of the transmission network as system flows increase in future.
|
NOA 2021/22 Refresh Recommendation: Hold |
NEP1
Power control device along Blyth to Tynemouth and Blyth to South Shields |
Type: Control power flow
Status: Strategic Optioneering
Boundaries: B7aI
Region: North England |
Install an additional power control device along the Blyth to Tynemouth and Blyth to South Shields 275 kV overhead line route. This would improve the capability to control the power flows from north to south of the transmission network.
