Every number, graded

The Atlas treats evidence quality as a first-class dimension. This page is the audit trail: which fields are reported by operators, which are documented estimates, which are class-band inferences, and where the dataset is simply silent.

Confidence distribution across parameters

Count of documented fields in each confidence band. The bulk of this dataset is modelled, not reported.

Reading the grades

What each confidence level means

4–5 · reported

Published by the operator or a regulator, in a named document.

3 · documented estimate

Derived from a credible published figure with a stated method.

2 · modelled

Computed from documented coefficients applied to this facility.

1 · class-band inference

Assigned from a facility-class or land-use band, not this facility.

0 · no record

No value located. Shown as an em dash, never as a zero.

Structural silence

The field does not exist in the dataset: Scope 1, Scope 3, measured noise, metered energy.

Land_Use_Context / Sensitivitycategory / 0-1Land-use class of the facility's area and its community-sensitivity weight.Assigned per area, so every facility in an estate shares a value.
Population_1km / Population_5kmpersonsDensity band x pi x r^2, with a 0.60 radial decay factor applied at 5 km.NOT a raster zonal statistic. Replace with GHSL or WorldPop against real coordinates before publication.
Community_Complaintscount/yr0 for every facility.0 MEANS 'no publicly documented facility-specific complaint was found'. It does NOT mean none exist.
Regulatory_Planning_Constraint0-1Cluster-level score for restrictive instruments in force (moratoria, connection bans, zoning frameworks).Cluster-level, so it cannot distinguish two facilities in the same market.
Documented_Objection_Record0-1Cluster-level score for the strength of the public objection / litigation record.Strong for the USA and Ireland; near-absent for India, Brazil and Singapore - an evidence gap, not an absence of impact.
Local_Infrastructure_Pressure_pct%Facility capacity as a share of its cluster's total capacity.A concentration measure, not a grid-headroom measure.
Employment_Estimate_FTEjobsCapacity_MW x 5 permanent roles per MW.Highly uncertain and varies enormously between colocation and hyperscale operating models.
P1..P6 pillar scores0-100Weighted sum of normalised sub-indicators (Methodology section 5).Inherits the confidence of its weakest input; P5 and P6 are Confidence 1-2 throughout.
Composite_Score / Risk_Class0-100 / categoryWeighted mean of the six pillars; class = quartile of this dataset.Relative to this dataset only. Not an absolute risk statement about any facility.
Record_Confidence0-5Mean of the field confidences for capacity, PUE, WUE, coordinates, status, year and context.A summary; always check the per-field confidence columns before relying on a single value.

Where the workbook's bottom-up total diverges from a published market figure, the divergence is recorded in the quality-control table rather than reconciled away. Reading those rows is the fastest way to understand how much weight the totals can bear.
