Analysis: What Does This Simulation Prove?
What this proves: Grid companies like Ellevio only measure peaks on weekdays (Monday-Friday).
Weekend consumption doesn't count toward your effekttariff, even if it's very high. This simulation has extremely
high weekend consumption (10 kW) and moderate weekday consumption (4 kW) to demonstrate that only weekday peaks
appear in the final calculation. This means you can safely run high-power activities on weekends without affecting
your monthly peak average - great for weekend EV charging or sauna sessions!

Why No Savings? This simulation has no battery configured. The effekttariff node outputs a
current limit signal, but without a battery to discharge, there's nothing to cover the difference when
consumption exceeds the limit. The grid must supply all power, so peaks cannot be reduced.
What This Shows: The system correctly tracks your top 3 peaks during
peak hours and calculates your effektavgift at approximately 200 SEK/month.
This monitoring alone is valuable for understanding your consumption patterns.
To Actually Reduce Peaks: You need a battery that can discharge during high-consumption moments.
The node tells your ESS "limit grid to X amps" - the battery covers the rest. See the batteryCharging
scenario for a 40-50% reduction example, potentially saving
80-100 SEK/month.
