Your electric water heater kicks in when night-time prices start? Or some other object set to turn on when night-time prices start at 22:00.
Seems like night time electric devices kicks in, they are controlled by contactor in your “electric/fuse cabinet”. Inpulse to this contactor is given by your electric meter. If are near the cabinet that time (22:00 – 22:30) you might hear the cotactor changing state. Water heater is cause that spike.
That’s the water heater, even if you don’t use hot water (people usually do use it washing hands, kitchen sink, shower) it will go on either at 22, 23 or 00 (10pm, 11pm, 00am). Water doesn’t stay hot so it warms it up everyday, maybe you have it set even to 70c or something so it will take more energy to heat.
The trigger time usually changes by day to even out the electric grid (it would be bad if approx 1.5M water heaters turned on at the same time).
