Electricity Prices to Surge for Solar Panel Owners in Wallonia in 2025
Energy Bills Set to Surge for Belgian Homeowners with Solar Panels
Wallonia, Belgium – Homeowners in Wallonia with solar panels are facing a meaningful increase in energy distribution costs in 2025.
The “prosumer” tariff, which applies to households that generate their own electricity through solar panels, will see a sharp rise across various energy providers. Ores, one of the largest distributors, will see the prosumer tariff jump by 31%, from €62.45 to €82.04 per kilowatt (kW). For a typical 5 kW solar panel system, this translates to an annual increase from €312 to €410.
Other providers are also implementing ample increases. Resa will see a 22% hike, AIEG a 34% increase, and AIESH a 19% rise. The Régie de Wavre will see an 18% increase.
The Cwape, the Walloon Association of energy Consumers, attributes the disproportionate increase in the prosumer tariff compared to the general distribution tariff to the inclusion of Elia’s transmission network fees. Elia, the operator of Belgium’s high-voltage grid, is facing significant cost increases in 2025, which are being passed on to consumers.
While homeowners with solar panels will see these Elia costs reflected directly in their prosumer tariff, conventional electricity consumers will also be impacted. their Elia costs will be calculated separately and added to their overall bill. according to the Cwape,Elia’s fees will add €105.60 to the annual electricity bill for an average household in Wallonia, a 51% increase from 2024.
Businesses Brace for Impact
The news isn’t just affecting homeowners. Businesses connected to the medium-voltage network will also face a 31% average increase in distribution tariffs in 2025. Ores will see the steepest rise at 45%.

“While homeowners with solar panels will see these Elia costs reflected directly in their prosumer tariff,” explains a spokesperson from CWape, “conventional electricity consumers will also be impacted. Their Elia costs will be calculated separately and added to their overall bill. According to our calculations, Elia’s fees will add €105.60 to the annual electricity bill for an average household in wallonia,a 51% increase from 2024.”
The impact extends beyond homeowners. Business connected to the medium-voltage network also face a 31% average increase in distribution tariffs in 2025, with Ores seeing the steepest rise at 45%.
