Energy community in Wallonia: framework, measured examples and next steps

Energy sharing is taking off in Wallonia

An energy community allows Walloon businesses, municipalities, associations or households to share locally produced renewable electricity with one another. Wallonia combines two assets for this model: a dense fabric of SMEs, business parks and facilities with large roofs — and some of the country's heaviest electricity bills for professional users.

The movement is under way: the communities managed by RaYSun already count 132 supply points in Wallonia, from Tournai to Aubange, and in May 2025 the Region saw the launch of its first multi-site energy sharing, at Brasserie du Bocq (Purnode, in the municipality of Yvoir).

The Walloon legal framework, in brief

• The legislation — the Walloon decree transposes the European directives and organises renewable energy communities (RECs), citizen energy communities (CECs) and sharing within a single building.
• The regulator — the CWaPE (the Walloon energy commission) authorises and supervises the communities.
• The network operators — ORES and RESA cover most of the territory, alongside more local distribution system operators (DSOs) (AIEG, AIESH, REW): they provide the quarter-hourly metering data and apply the allocation.
• Proximity — perimeter rules apply depending on the type of community; the preliminary study checks that the prospective members can actually share with one another.
• One EAN, one operation — as everywhere in Belgium, a meter can only be attached to one energy-sharing operation at a time.

General information, not legal advice. RaYSun handles the regulatory formalities (CWaPE file, contracts, DSO relations) on behalf of its members.

What the Walloon operations deliver, in measured figures

• Brasserie du Bocq — Wallonia's first multi-site energy sharing, housed within the WalloWatt community: 4 members (the brewery's buildings and employees), 167,3 MWh shared in 12 months, 68,6 % of the solar injection consumed locally rather than sold back at rock-bottom prices.
• The Hannut business park — 8 companies on the business park (Goossens, Destexhe, Polycar, Ampi, SPS and their neighbours) exchange their electricity to cut their bills — a local dynamic praised by the regional press, and this is only the beginning.
• Energilia Wallonie — RaYSun's turnkey energy-sharing operation on the Walloon side: 30 members and 5 585 MWh of shareable energy per year identified, and growing steadily.

Who is it relevant for in Wallonia?

• SMEs and industry — especially above ~500 MWh/year of consumption, where the price gap translates into tens of thousands of euros.
• Business parks — sharing between neighbours on a business park smooths the profiles and maximises the value of the roofs (the Hannut business park model).
• Multi-site companies — share between your own buildings, then with your ecosystem (the Brasserie du Bocq model).
• Municipalities and public bodies — put public roofs to work for the benefit of the local area.
• Solar producers — any surplus injected at rock-bottom prices is lost revenue that sharing corrects.

How do you get started?

Two routes, as everywhere in Belgium: join an existing operation (Energilia, a few weeks) or create a dedicated community (multi-site, local area or real estate, a few months). In both cases, RaYSun starts with a free study based on your real consumption data — and its operational team is based in Ciney, in the heart of Wallonia.
