The UK electricity grid

The transmission system mapped as a supply chain and as an institution, from raw materials through to the customer. Every node and flow exists because a primary document says so.

48 nodes and 58 flows, laid out left to right from raw inputs to the customer. 2,454 facts from 426 primary sources, 104 actors, 56 commitments and 532 recorded gaps. State at 23 September 2026. The report explains what it shows.
