Upgrade and/or rebuild the circuits and equipment between Longside (Peterhead 2), Peterhead, Persley, Kintore, Fetteresso, Alyth, and Kincardine

Establish a 400 kV substation at Spittal and construct a HVDC subsea link from the new 400 kV substation at Spittal to the existing 400 kV substation at Peterhead.

New network need from North Wales to South Wales. This would improve the west region by proposing an alternative route to the generation located in North Wales

Leading The Way: 2037

System Transformation: 2037

Upgrade the cable section on the existing Pentir to Trawsfynydd circuit to allow this to operate at higher temperatures and increase the circuits thermal rating.

Replace the conductors on the existing circuit between Pentir and Trawsfynydd with a higher capacity then was previosuly recommended

New circuit in North Wales with a higher capacity then was previosuly recommended

Leading The Way: 2037

System Transformation: 2037

Construct a second circuit in North Wales, making use of the existing transmission infrastructure to facilitate power transfer requirements across the relevant boundaries. Associated substation works are required at each end.

Two new 225 MVAr switched capacitors (MSCs) at Penwortham substations would provide voltage support around Mersey area as system flows increase in future.
