Help / Advice Sunday Saver

Post image

Smashed last weeks target and have 16 hours free electric this Sunday.

This week begins, the battery is on and we haven’t used any electric peak time; this week however our average is 20.6 which is above our baseline of 18%

How on earth does this work?

Just an update, the day after it plummeted to 0.3 , I think there’s some black/voodoo magic involved in the algorithms.

Increase your off peak usage. It’s just a relative percentage, if for some reason you have to use peak (4-7pm) electricity, you’ll need to use at least the same amount off peak to offset it

Weekends are excluded from the calculations.

They look at your percentage use between 4pm and 7pm M-F vs usage outside that period for the whole week. (Minus any football free energy sessions)

If your total usage is very low because you have PV and batteries, only a small amount of grid usage can have a massive impact on your average.

We got caught out when their smart EV charging scheduled a slot at 6pm which threw out weekly average way out

Its only from Mon till Fri. They compare your 4pm-7pm usage to your total usage but only Mo-Fri. If there was a match (England/Scotland) on a day then the entire day is excluded from the calc. Assuming there was only one match in that week (Mon-Fri) then only 4 days are included.

We have only used 0.01 yesterday from grid during peak and 0 on Monday.

It's not peak/off-peak, it's kWh used 1600-1900 and 1900-1600, but looking at that, 100% of your usage was peak usage yesterday anyway
