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.
Worth pursuing. The strongest paper case in GB open data: 185.1 MVA published at the BSP, no green belt or conservation constraint, and land that could carry a campus — a 51.6 ha parcel 233 m from the substation, buildable ground north and east, flood confined to the south-west quadrant.
One unknown decides it: the demand-connection queue is private, so the 185.1 may already be spoken for. A free NGED budget estimate settles that in ~10 working days. The assembly story is unusually simple — Derby City Council holds both sides of Sinfin Lane and Infinity Park: one landlord to talk to first, not thirty. Hallam Land on the zone's edge says a strategic promoter already rates the area.
| Area | From BSP | INSPIRE id | Screen |
|---|---|---|---|
| 51.6 ha | 233 m | 27535254 | clear |
| 12.8 ha | 117 m | 27646112 | clear |
| 16.2 ha | 596 m | 27640228 | clear |
| 13.7 ha | 706 m | 27615674 | clear |
| 14.1 ha | 857 m | 57351683 | clear |
| 14.8 ha | 1,192 m | 27443901 | clear |
| 20.2 ha | 976 m | 62075271 | flood 2/3 |
Every registered parcel over 10 ha in the study area. A campus needs roughly 10–20 ha contiguous; seven holdings here pass that bar on their own, six clear of flood zone. Screen = flood / green belt test at the parcel centroid — boundary overlaps need the parcel-level check. INSPIRE id is not a title number; the owner of each parcel is a £7 official copy away, listed under next moves.

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.
