Electricity Time-of-Use Comparison / methodology notes

About & corrections

Rate Replay is a focused workspace for electricity time-of-use comparison.

A useful result, with the assumptions attached

Replay interval consumption against explicit flat and two-period tariffs. Separate same-usage savings from hypothetical load shifting.

What this release includes

An interactive local-first tool, editable records where relevant, CSV templates and imports, transparent result tables, optional browser-local saved plans, JSON export and restore, a printable report, and source-linked methodology. A shared backend, verified live catalogs, subscriptions, user accounts, email notifications, and independently audited source coverage are not included.

Report a correction

Use the source-code link in the footer to open an issue with anonymized inputs, the expected result, the actual result, and the method version. Calculation bugs and missing evidence should be reported separately. Source records are not altered because of advertising or sponsorship.

No invented authority

These are user-entered tariff scenarios, not verified current offers or guaranteed savings. Reconcile a complete bill and all tariff terms before switching. This tool does not claim certification, professional endorsement, complete source coverage, or market-leading accuracy.
