The grid on a map
Carbon intensity across Britain's 14 distribution regions, with the power crossing each interconnector.
At 19:27 GMT on 7 November 2026, the cleanest electricity in Great Britain was in North Scotland at 0 gCO₂/kWh, and the most carbon-intensive was in South West England at 393 gCO₂/kWh. These are forecasts for the current half hour.

Common questions
What are the regions on this map?
They're the areas served by Britain's 14 distribution networks, the companies that run the local wires. They aren't energy suppliers, and you can't choose yours.
Why is the north often greener than the south?
Scotland and the north have plenty of wind and relatively little demand. Further south, more of the power comes from gas and imports.
What do the arrows show?
Power moving through the subsea cables to and from Britain's neighbours. An arrow pointing at the coast is an import, and a thicker one means the cable is closer to full capacity. Their positions are approximate.
