"Saved" always uses peak tariff rate even if the moment that the power is saved was off peak


#1

“Saved” always uses peak tariff rate even if the moment that the power is saved was off peak.

My example
Peak: $0.55 (Mon-Fri 1500-2100)
Off peak: $0.15474 (all weekend is off peak)
Feed in tariff: $0.07135
Daily supply charge: $0.455989

Sun 15/Apr 2018
Generated: 31.191kWh
Exported: 17.025kWh
Consumption: 24.645kWh
Imported: 10.479kWh
Saved: Generation - Export = Consumption - Import = 14.166kWh

From the detailed page:
Credit = 17.025 * 0.07135 = $1.21 (correct)
Debit = (10.479 * 0.15474) + 0.455989 = $2.08 (correct)
Saved = 14.166 * 0.55 = $7.79 (incorrect). It should be 14.166 * 0.15474 = $2.19 because Sunday was all off-peak

The ‘saved’ calculation is overly generous or more one might say incorrect as it does not attribute savings to the correct tariff at the time of metering.

Am I missing something here?

This would be a enhancement to use TOU tariffs.

It will only work on dates where the system has peak, shoulder and off peak import data recorded.

Changed this topic to an ‘Idea’.

This has been implemented.

Yesterdays saved 11-June has dropped from $3.61 to $2.04
