Tumble dryer on.
Croissants cooking in the oven.
Kettle boiling.
Battery charging.
At -2p/kWh it won't quite pay for an Xmas present - but certainly fun to see what sort of odd behaviours it drives.
Our 4.8kWh battery took advantage of the negative electricity pricing yesterday.
It charged when power cost ≤ £0.00 and discharged the rest of the time.
Basically filled and emptied twice.
The results are in!
On Xmas eve, our home electricity use cost us… -10p!
Yup, our electricity company paid us a couple of shillings. Not enough for a mince pie, obviously. But the amount we used would have normally cost about £7 (24kWh * £0.30).
NB Octopus can't show negative pricing on its graphs either 😆
