From January 1, 2026, Wallonia will introduce a new tariff structure for electricity, designed to encourage more responsible consumption and support the energy transition. This reform, validated by the Walloon Energy Commission (CWaPE), will apply to users of the low-voltage distribution network, whether they are equipped with mechanical or smart meters.
The new pricing scheme is divided into three time bands, each associated with a specific tariff:
🟢 Green hours (lowest rate) :
🕐 1 am to 7am (night) and 11am to 5pm (solar hours).
🟠 Orange hours (intermediate rate):
🕐 7am to 11am and 10pm to 1am.
🔴 Red hours (highest rate):
🕐 5 pm to 10pm.
The red hours rate will be about 5 times higher than the green hours rate, and the orange hours rate about 3 times higher.
No penalty for essential uses: meal preparation, for example, will not be penalized, even if it takes place during red hours.
Watch out for energy-hungry appliances: using appliances such as water heaters or charging electric vehicles during red hours without adapting your consumption could lead to an increase in your distribution costs.
From 2026, the distinction between weekday and weekend rates will disappear. Time slots will be the same every day, simplifying the management of your consumption.
Your meters, whether mechanical or communicating, will automatically switch over to the new tariff structure without requiring any intervention at home. This transition is designed to facilitate the adoption of the new tariff structure for all users.
To take advantage of the advantageous green hour rates, here are a few tips:
Program your energy-hungry appliances (washing machines, dishwashers, water heaters) during green hours.
Charge your electric vehicle mainly during green hours.
Adapt your consumption to the new time slots to avoid red hours.
The tariff reform will lead to an average 8% increase in distribution costs for Walloon households from 2026, or around €30 extra per year for an average residential customer consuming 3,500 kWh per year.
With the arrival of the new electricity tariffs in Wallonia, optimizing your consumption becomes essential. Installing photovoltaic panels combined with a storage battery is an effective solution for limiting the impact of rising costs.
Photovoltaic panels produce electricity mainly between 11:00 and 17:00 - during green hours, when the tariff is lowest.
The battery stores excess electricity for later use, particularly in the evening during red hours, when the tariff is highest.
This autonomy enables you to reduce your consumption of electricity from the grid during expensive hours, and lower your overall bill.
Significant reduction in bill by consuming your own stored energy.
Better management of consumption, by adapting the use of energy-hungry appliances.
Participation in the energy transition via clean, renewable energy.
Protection against rising prices by limiting dependence on the grid during expensive hours.
The initial investment is higher, but tariff reform and expected price rises make this solution profitable in the medium term, thanks to the savings achieved.
FAQ – New electricity pricing in Wallonia (2026)
Starting January 2026, Wallonia introduces a new tariff structure based on three time slots: green hours (lowest rate), orange hours (intermediate rate) and red hours (highest rate). Rates will be the same every day, with no weekday/weekend distinction.
Red hours will cost about 5 times more than green hours, and orange hours about 3 times more.
The goal is to encourage consumers to shift their usage to times when electricity is abundant and cheaper, supporting the energy transition and avoiding network overload during peak demand.
No, all meters (mechanical or smart) will automatically switch to the new tariff structure. No home intervention is needed.
No, the distinction disappears: time slots and rates are the same every day of the week.
The reform will result in an average increase of 8% in distribution costs, about €30 more per year for typical consumption of 3,500 kWh. The actual impact depends on how well you adjust your consumption to cheaper hours.
Households that do not adjust and mainly consume during red hours will see their bills rise further. It’s advisable to gradually adjust your usage or invest in self-consumption solutions.
Yes, prosumers are affected: the end of compensation and introduction of incentive pricing make self-consumption and energy storage more relevant to optimize installation profitability.
