How does the capacity tariff in Flanders work?

Short answer

Part of the grid charges depends on your highest quarter-hour consumption per month. Everyone pays for at least 2.5 kW.

Explanation

The digital meter measures per quarter hour. The highest quarter of the month is your monthly peak. The average of 12 monthly peaks determines what you pay. The average Flemish household has a monthly peak of about 4.24 kW.

Rules of thumb

Minimum: 2.5 kW. [SW-S53]
2026: about € 53.39 per kW per year (varies by grid operator). [SW-S53]
Spread heavy appliances (heat pump, tumble dryer, dishwasher, charger) over different quarter hours. [SW-S53]

Pitfalls

With a conventional meter you pay a fixed contribution equal to the minimum; with a digital meter it depends on your peaks. [SW-S53]
