Households in Wallonia will soon have a digital meter, just like their neighbours in Flanders. Additionally, new tariffs will be introduced to optimise energy efficiency. It will change how electricity is measured and billed, and how you can use automation to turn these changes to your advantage.

What changes in 2026

The digital meter brings three major shifts:

• Separate tariffication of consumption and injection.
• Limited compensation for solar energy sent to the grid.
• Introduction of the impact tariff, with strong price differences between peak, medium, and eco hours.

In addition, dynamic tariffs will be implemented, with prices changing every 15 minutes according to supply and demand.

Together, these systems will make electricity cheaper at certain hours and more expensive at others.

Without adapting, households risk higher bills and lower solar returns.

How to avoid higher energy costs

Energy production and transportation account for approximately 75% of your total bill. That’s where the new tariffs apply, and consequently, where savings are possible.

To benefit, households must shift consumption to cheaper hours and use more of their own solar energy instead of injecting it into the grid.

This is complex to manage manually, but an Energy Management System (EMS) can do it automatically.

What is an EMS?

An EMS or energy management system monitors and controls how energy is used, produced, and stored in the home.

What it does

• Monitoring real-time production, consumption, and storage.
• Controlling appliances automatically when solar production is high, or tariffs are low.
• Optimising flows to avoid peaks and reduce costs.

With an EMS, households can optimise up to 75% of their energy expenses. Without lifting a finger.

Niko Home Control

Niko Home Control includes a full EMS that:

• Schedules devices during eco hours.
• Shifts EV charging to low-cost periods (saving up to 50%).
• Avoids consumption during peak hours.
• Increases self-consumption by using solar energy directly for heating water, charging EVs, or powering appliances.

All this happens automatically.

Proven return on investment

We have run a simulation based on 1.200 installations (data 2024). We’ve taken into account the new tariffs of 2026 in Wallonia. They show the following results.

Situation

You live in Wallonia and you want to charge your car at 10 kW for the next 24 hours ...

• Without an EMS: You spend € 1,225.77 per year on energy costs.
• With the EMS of Niko Home Control: You spend € 707.57 per year on energy costs

This results in an ROI of € 518.20 per year on average.

The system automatically shifts energy use to the most favourable tariff periods (dynamic + impact tariff), making it easy for customers to benefit from the new pricing model.
