The North's largest published headroom, on the M621 edge of a live AI data centre market. And the report that shows what the layer is for: the land test fails here — green belt starts 174 m from the substation and the ownership is housing, not industry.
Does not pass as screened. The power is real — 137.3 MW, the North's largest published figure, four miles from Microsoft's live Leeds site. The land is not: green belt starts 174 m from the substation and takes most of the big parcels, and what remains is council housing and registered-provider stock. No commercial or industrial assembler holds meaningful ground here.
The recoverable move is a different ring, not a different verdict: the same substation serves the M621 / Gelderd Road industrial estates 2–3 km out, which this study box does not cover. That re-run is next move 2. This report stays published because a clean negative is what the screen is for.
| Area | From BSP | INSPIRE id | Screen |
|---|---|---|---|
| 26.0 ha | 580 m | 61825814 | green belt |
| 18.5 ha | 821 m | 62153939 | clear |
| 17.6 ha | 1,173 m | 26369223 | green belt |
| 14.7 ha | 542 m | 26299954 | clear |
| 10.3 ha | 1,035 m | 59565425 | green belt |
Every registered parcel over 10 ha in the study area. Three of five sit in green belt at the parcel centroid; the two that screen clear sit in a zone whose register is council housing and registered-provider stock, and the greenfield options carry Grade 2 agricultural land — best-and-most-versatile conflict on top of the belt argument. That is the fail, stated with the parcels that prove it. Screen at parcel centroid; boundary overlaps need the parcel-level check.

Northern Powergrid NDP thermal demand headroom, DFES 2026 Holistic Transition scenario. NPG publishes MW forecasts by year, not a single MVA figure — treated as ≈MVA at near-unity power factor. Third-largest published figure in GB; largest outside NGED territory. The demand queue is not public — the figure is unverified against live applications until an NPG budget estimate confirms it.

*Study-area counts (Leeds district, 402 matched roads, LS10–12/27). 5,252 proprietors screened, 627 matched to the signals layer, 84 flagged — flags sit in the small-landlord tail, nowhere strategic. The table is the finding: no commercial or industrial assembler holds meaningful ground here. HMLR CCOD Jun 2026.

Comparable: Microsoft's live Leeds site is 4 miles east at Skelton Grange — ex-power-station plot, 27 acres, sold by Harworth for £51.2m (Jun 2024; resolution to grant Apr 2026). Legacy grid plus assembled single-owner land — the two layers this report screens.
