Disclosure control & data provenance
Grouping the dataset into 11 month groups, 0 were safe to publish and 11 were withheld under the rules below. Across 4800 meter reads, 0.0% of records and 0.0% of total total consumption remain in the published output, with worst-case re-identification risk of 0% (None).
Anomalies are flagged, not dropped; rows failing validation are quarantined as rejected. 4800 reads (100.0%) lack coordinates and are excluded from spatial views.

Energy burden & equity
Every census tract was suppressed — no tract had at least 15 accounts with an ACS median income on record.
Explore burden live →Differential privacy — an alternative release
An alternative to suppression: instead of hiding small groups, calibrated Laplace noise is added to each count (ε = 1.0, scale b = 1.0) so no individual's presence can be inferred while totals stay useful. Mean absolute error ±0.7 across 3 groups.
