The largest published demand headroom in GB open grid data, beside a council-led innovation park with its own under-used substation. SE Derby: Sinfin, Infinity Park, the Rolls-Royce campus.
| Substation | Role | Firm | Avail. | RAG |
|---|---|---|---|---|
| Derby South 132/33kV | BSP | 270 | 185.1 | green |
| Infinity Park 33/11kV | primary | 23 | 17.3 | green |
| Allenton 33/11kV | primary | 38 | 13.0 | green |
| Sinfin Lane 33/11kV | primary | 18.8 | 4.1 | amber |
MVA. NGED LTDS Capacity Heatmap, 27 Jul 2026 cut. A campus connects at 33/132kV — the BSP figure is the one that matters. Headroom is a planning figure, not a connection offer — and the demand-connection queue is not public, so any published figure can already be spoken for by an application the open data cannot see. Treat 185.1 as unverified until a free NGED budget estimate confirms it; that is the first next step, not a formality.
