Redlineo

Utilities & energy

PUC tariff filing redline — proven, not just marked up.

A tariff sheet was revised, and someone has to show — and be able to prove — exactly what changed. Public utility commissions expect redlined tariff pages: the closest cousin of insurance SERFF practice. Redlineo produces that exhibit, and every output carries its own proof.

Same primitive, PUC vocabulary

The analogous filing, the analogous rate table.

  • The filing

    Tariff sheets filed with a PUC

    Tariff sheets filed with public utility commissions — PUCs expect redlined tariff pages, the closest cousin of SERFF practice. The strikeout/underline exhibit this tool produces is exactly that artifact, and the full redline is what you file. And the practice is not US-only: energy, water and telecom regulators across Europe, Canada and Australia require tariff filings with revised schedules — the same spreadsheet-heavy comparison.

  • The rate table

    Rate schedules in spreadsheets

    Rate schedules live in workbooks. Drop the approved and revised versions: the print areas become a paged Word redline mirroring the printed tariff pages, or a colored Excel review copy for reviewers who work in the spreadsheet. Rows and columns re-synchronize, so one inserted row shows as one inserted row.

What carries over unchanged

Every proof and report primitive comes with it.

  • Verified redlines. Accepting every change reproduces the revised tariff; rejecting every change restores the approved one — re-checked on every run and stamped ✔.
  • The certificate. SHA-256 fingerprints of the exact input files, recomputable by anyone with sha256sum.
  • A report with links. Every change numbered — none truncated — each line a click-to-jump link; rate impact computed for changed cells.
  • Excerpts on demand. "Changed content only" trims the output to the changed tariff pages, every omission explicitly marked; the full redline stays the filing artifact.
  • Metadata scrubbed. No leaked author names, company fields, editing time or revision fingerprints on any output.
  • The DMS round-trip. Compare versions straight from Alfresco and save the reviewed output back — integrity-verified before it is filed.
Configured for your conventions The tool is domain-configurable — nothing is hardcoded. The metadata extraction conventions, the assertions ("effective date must bump"), and the per-jurisdiction profiles live in editable application.yaml. Adapting it to a utility's schedule numbering and commission conventions is a configuration exercise, not a new product.
