Keep years of AMI interval reads — ~20× smaller, queryable, and erasable per meter
AT-1 stores smart-meter / AMI interval data ~20× smaller (1.5× past xz), byte-for-byte lossless, in one archive you can still query — pull a single meter or a time window without rehydrating — and delete one meter or customer's entire history on request, with a signed erasure certificate.
Who it's for: Utilities, DSOs and metering-data-management (MDM) teams holding years of interval reads for regulatory retention — where the data is both an analytics asset and personal data under GDPR.
How it fits: Tier cold AMI / MDM archives off your warehouse or object store. Reads come back byte-exact and queryable by meter_idand time, so analytics and billing re-runs don't need a full restore — and right-to-erasure deletes a single subject's history without rebuilding the archive. One verified file: compressed, queryable, and audit-grade.
Measured on a real multi-meter archive built from public UCI household-power interval data (2,000 meters), byte-for-byte lossless: 19.9× vs raw, 1.54× smaller than xz-9. Part of the Regulated Archive family.
Put a number on your meter data.
We'll run it on a slice of your own AMI export and send back the storage cut, a live per-meter erasure, and a one-page proof — verified byte-for-byte.
