Analysis: What Does This Simulation Prove?
What this proves: The real power of effekttariff optimization comes with a home battery.
This simulation shows how the system charges the battery during off-peak hours (before 07:00) and then discharges
during peak hours to reduce grid consumption. With a 20 kWh battery and 5 kW charge/discharge rate, the system
can significantly shave peaks. Watch the SOC chart: it rises during night hours and drops during the day as the
battery supplements grid power. The comparison shows the dramatic difference between baseline peaks and achieved
peaks with battery intervention.

Monthly Cost Impact: Based on typical Swedish effekttariff rates (~50 SEK/kW/month),
this 1.5 kW reduction saves approximately
75 SEK/month on the power tariff portion of your grid fee.
Battery Contribution: The battery discharged during 42 peak hours
with an average discharge rate of 1.3 kW to shave consumption peaks.
