To know your existing peak consumption, please contact your grid operator.

As the capacity rate only applies in Flanders and Fluvius is the power grid operator for the whole of Flanders, you will find all information about your (peak) consumption on My Fluvius, under the section Network costs.
On this page (in Dutch), Fluvius explains the terms Quarter Peak, Monthly Peak and Billing Peak using 2 videos. For the calculation of the Average Monthly Peak, one starts from January 2023. That is when the capacity rate was introduced.
If you cannot find any information from your power grid operator, the table below may serve as an initial guide:
| Home grid connection | Minimum capacity |
Recommended capacity |
| 1F (1 x 230V) | 1,4 kW | 4 kW |
| 1F (3 x 230V) | 1,4 kW | 4 kW |
| 3F (3 x 400V + N) | 4,2 kW | 5 kW |
The minimum capacity is the lower limit required to power the charging station sufficiently to charge your vehicle. If less capacity is available due to consumption from other energy users in your home network, your vehicle will be unable to charge. As soon as these other users cease their consumption, your vehicle will start charging again.
The recommended capacity is the ideal power required to make your vehicle charge in optimal fashion.
Hopefully, this guide gives you some insights to make an reasoned choice.
If your charging station is connected 3-phase and the available power is lower than 4500W your car will not charge. Unless your charging station is equipped to switch between 3-phase and mono-phase.
In the latter case, if the power available is lower than 4500W, the charging station will switch to single-phase charging. Once the available power rises above 5000W, the charging station switches back to 3-phase charging (if it was connected 3-phase).
