Capaciteitstarief Simulation Report

What this proves: In Flanders, a single 15-minute period of 11kW EV charging creates an 11kW peak that affects your capacity fee for the entire year. This simulation shows a typical Flemish household with occasional evening EV charging sessions. Without intervention, these EV charging peaks become your monthly capacity, potentially costing an extra €300-400/year compared to a lower baseline. With a home battery, these peaks can be shaved by discharging stored energy during EV charging. This demonstrates why peak shaving is especially valuable for EV owners in Flanders - limiting charging peaks directly reduces your annual capacity fee.

Annual Cost Impact: The Flemish capacity tariff costs approximately €50/kW/year based on your 12-month rolling average. This 0 kW reduction saves approximately €0/year (€0/month).

Battery Contribution: The battery discharged during 18 intervals with an average discharge rate of 0.8 kW to shave consumption peaks.

Why this matters in Flanders: A single 15-minute high-power event (like 11kW EV charging) sets your monthly peak, which then affects your annual fee for 12 months. Peak shaving is especially valuable here.
