How Rate Replay calculates your result
Replay interval consumption against explicit flat and two-period tariffs. Separate same-usage savings from hypothetical load shifting.
Start with evidence, not a score
Import chronological interval usage with explicit UTC offsets and the actual interval duration. Reject overlap and expose gaps. Assign energy to peak and off-peak windows in the utility timezone, then apply the entered tariff components.
Read the assumptions
Compare both tariffs on exactly the same consumption. Show load shifting only as a separate scenario, with unmodeled tariff rules disclosed. These are user-entered tariff scenarios, not verified current offers or guaranteed savings. Reconcile a complete bill and all tariff terms before switching.
Use a reproducible workflow
Enter your own measurements or import records using the published CSV schema. Save a local scenario before making a change, compare the result, and export a copy with the assumptions intact. Example inputs are not a verified catalog or a live data feed. The source references explain the underlying terminology; they do not independently verify information you enter.
