The charts page focuses a lot on the North and South Scotland grids. If you’re wondering where these North and South areas begin and end, there are now some very detailed maps on the new maps page that show you the boundaries of each network. South touches on the bottom of Loch Lomond, includes Stirling and covers most of Fife, so check them out, it’s perhaps not what you’d expect. Having watched South Scotland rack up an carbon intensity of only 3.1gms CO₂ / kWh last month feels even better when you realise that the entire Central Belt, Stirling and Fife are running on that level of decarbonised electricity.

Each of grid areas has a DNO, (Distribution Network Operators) which plays a crucial role in delivering power from the national transmission system to homes and businesses.

DNOs own and operate the lower voltage networks (typically 132kV and below) that branch out from the high-voltage transmission system. They maintain the substations, transformers, overhead lines, and underground cables that form the "last mile" of electricity delivery.

Their role in balancing the grid is key and through their planning and investment in new substations they can help or hinder the transition. This is something we’ll look at in more depth in the future, but in short, no matter how much new renewable installed capacity you create it doesn’t help with the energy transition if those electrons if it cannot make it to the grid due to lack of capacity.
