See what you'd pay on a standard tariff vs the 10s Smart contract — with the full capacity tariff calculation for Flanders.
CREG-compliant · reference consumption 3,500 kWh/yr · Belgium 2025–2026Since January 2023, part of your grid cost is based on your peak 15-minute draw each month — not just total consumption. The higher your simultaneous load, the higher your capacity tariff.
These run on real-time Elia quarter-hour pricing. 10s automatically shifts them to the cheapest windows — including negative-price periods when you're paid to consume.

Neither the standard dynamic nor the 10s Smart costs include the supplier's commercial margin. The fixed market reference already embeds a typical margin — the dynamic figures do not.
Belgian dynamic tariff providers typically charge €0.015–0.025/kWh above spot plus an annual fee of approximately €50–80/yr (Luminus: €0.021/kWh + €75/yr; Engie: spot × coefficient + fixed constant).
