Flanders Basic - Flemish capacity tariff (capaciteitstarief) with 15-minute intervals and single peak per month
Analysis: What Does This Simulation Prove?
What this proves: The Flemish capacity tariff (capaciteitstarief) uses a different model than Sweden.
Instead of averaging multiple peaks, Flanders charges based on your single highest 15-minute peak each month. This simulation
shows how the system tracks quarter-hourly consumption and identifies the single highest peak. Because only one peak matters,
a single high-power event (like EV charging) can dominate your monthly capacity fee. The system measures 24/7, all year -
there are no off-peak hours or seasons. This makes peak shaving with a battery even more valuable in Flanders.

Why No Savings? This simulation has no battery configured. The capaciteitstarief 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 highest 15-minute peak during the month.
Your current peak of 4 kW
results in an estimated annual capacity fee of €200.
To Actually Reduce Peaks: You need a battery that can discharge during high-consumption moments.
For example, reducing an 11 kW EV charging peak to 5 kW could save approximately
€300/year on your capacity tariff.
