As the energy transition gathers pace, Sibelga is constantly having to invest in strengthening its electricity network. To limit the impact on the community of private high-power requests, we are introducing a special rate that encourages more responsible use of resources.
What is the intervention rate?
The intervention rate for the development of the low-voltage network comes into force on 1 January 2025. It applies to requests to increase meter power or install a meter that meet the following 2 conditions:
- the power requested is greater than 9.2 kVA;
- and requires an on-site visit by Sibelga.
In this case, a one-off surcharge of €55 per kVA (excl. VAT - rates 2025), billed in 0.1 kVA increments, will be applied for:
- power requested above 9.2 kVA;
- or for existing power if it is already greater than 9.2 kVA.
NB: This surcharge does not apply to temporary connections (construction sites, fairs and festive events ).
Examples
Based on 2025 rates:
| Circuit breaker | Type of installation | kVA | Intervention rate |
|---|---|---|---|
| 32A | 1x230V | 7,4 kVA | €0 |
| 40A | 1x230V | 9,2 kVA | €0 |
| 25A | 3x230V | 10 kVA | €44 |
| 20A | 3Nx400V | 13,9 kVA | €258 |
| 25A | 3Nx400V | 17,3 kVA | €445 |
Please note
Please note that the intervention rate is in addition to the cost of any work carried out, such as the cost of installing a new meter or the basic cost of increasing the meter power.
Why this intervention rate?
Climate change is forcing us to reduce our dependence on fossil fuels in order to cut our greenhouse gas emissions.
This transition is leading to the adoption of new modes of consumption, such as electric cars and heat pumps, and therefore more electrification. However, the current network is not necessarily designed to absorb any peaks in consumption linked to these new uses. It is therefore vital that we strengthen it.
As a result, customers who wish to have access to increased power will have to pay the special intervention rate in order to do their bit to develop the network.
Our aim is to encourage more responsible use of the power grid.
How much power do I really need?
An average household usually requires no more than 5 to 6 kVA. The standard power rating is therefore 9.2 kVA (single-phase 40A).
If you have a smart meter, you can easily check the power you use via display code 1.6.0 (maximum average power in kW over ¼ hour used during the current month).
So you can easily assess your actual needs.
Always consult a professional
The smart meter provides an overview of your needs. However, you should always consult a qualified electrician before any work is carried out. They'll be able to tell you exactly how much power you need.
Shift towards a capacity rate
This intervention rate to develop the low-voltage network is a one-off payment made when a meter is installed or reinforced.
However, when it comes to the distribution rates paid monthly, a capacity factor (the power of your installation) is also taken into account.
2 factors are used to calculate the rate for use of the low-voltage electricity network (without peak measurement*):
- a rate per kWh consumed;
- and a capacity fee depending on the power made available.
A new pricing structure by 2028
Between now and 2028, this price structure will change: the capacity component will become increasingly important in relation to the rate per kWh consumed.
So the greater the power of your installation, the higher the network costs will be, regardless of the energy consumed.
It will therefore be essential not to overrate the power of your installation and to smooth out your consumption in order to keep your energy costs under control.
With this in mind, from 2025 onwards, all requests for depowering will be free of charge for power ratings below 56 kVA.
*For LV cases with peak measurement, the capacity part of the periodic rate is billed on the basis of the measured peak.
