Additional savings, which are not calculated: close to flat electricity consumption per day means lower electricity pricefrom the system operator. Also, demand response is possible (when you get paid by the system operator for helping inthe electric system compensation).
During our calculations, we did not take into account the estimated high scale electricity price increase.In Slovakia, the electricity price was doubled in 2019 and this tendency is expected in the other European countries.
