Scotland's Grid
Where the power is made, where it flows, and why wind farms get paid to stop
☰ Layers & filters
On the map
Grid boundaries
Lines where the network is squeezed. B4 and B6 are the main bottlenecks.
Power stations
Wind, hydro, nuclear and batteries, sized by capacity. Grouped when zoomed out.
Main grid (400 & 275 kV)
The high-voltage backbone that moves power across Scotland.
Animate flows
Moving glow shows power heading south towards demand. Direction is indicative, based on forecast boundary flows. Faster and brighter means closer to the limit; red means over it.
More detail
Regional lines (132 kV)
The next level down, linking towns and wind farms to the backbone.
Curtailed wind farms
Red rings sized by energy turned down in the last month.
Substations & spare capacity
SP Transmission substations show headroom: green = room to connect, red = nearly full.
Planned upgrades
SP Transmission reinforcement projects, with completion years.
New large demand
Big new users (e.g. hydrogen, data centres) contracted to connect to the SP Transmission network.
Future generation pipeline (SPT area)
Projects connected or contracted to SP Transmission, from early scoping to built.
