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