Additional savings, which are not calculated: close to flat electricity consumption per day means lower electricity price from the system operator. Also, demand response is possible (when you get paid by the system operator for helping in the electric system compensation).

During our calculations, we did not take into account the estimated high scale electricity price increase, we calculated with a 10% increase in every year, which is a very optimistic scenario, due to the lately huge increases in electricity price.
