NEPC
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 a 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.

OPN2
A new 400 kV double circuit between the existing Norton to Osbaldwick circuit and Poppleton and relevant 275 kV upgrades
Type: Develop new circuits
Status: Planning/consenting
Boundaries: B7aE; B7aI; B8
Region:
Construct a new 400 kV double circuit in Yorkshire to facilitate power transfer requirements across the relevant boundaries. This new circuit connects near Poppleton and tee-in to the existing Norton to Osbaldwick 400 kV circuit. 275 kV upgrades are delivered as part of the scope to increase power transfers. Substation works are also required.
