The project
Energilia Brussels is an energy-sharing operation at the scale of the Brussels region: hotels, shops, distributors, non-profits and local producers share their electricity there — with an advantage specific to the Brussels framework: shared energy is exempt from the renewable-energy levy, around €26/MWh, which makes sharing particularly attractive. Unlike a dedicated community, each organisation joins an existing operation: no structure to create, joining takes a few days in Brussels, and RaYSun manages everything — allocation, billing, member entries and exits.
Launched in late 2024 with a handful of pioneers, the operation today counts 54 members with very varied profiles — it is precisely this diversity (from bakeries to hotels, from workshops to non-profit headquarters) that makes sharing efficient.
Since launch, in real figures
Figures measured by our My Community monitoring platform on the operation's meters (late 2024 → end of June 2026):

Accelerating growth
The shared volume tells the story of the operation's ramp-up: 4,1 MWh in the first weeks of 2024, 923,8 MWh in 2025 — and already 1,427 MWh in the first half of 2026 alone, more than the entire previous year. Each new member increases the outlets for producers' surplus, and vice versa: that is the network effect of sharing.
The monthly detail, measured on the operation's meters, shows the same dynamic: shared volumes (in red) growing with each new member, driven by local production (in dark blue) that is put to better and better use:
Key takeaways
- Joining an existing operation is the shortest path to sharing: no structure to create, savings from the very first weeks.
- In Brussels, shared energy is exempt from the renewable-energy levy (≈ €26/MWh): the regulatory framework makes sharing extremely attractive there. Nothing prevents a Brussels business from joining an energy community today — the main obstacle remains simply a lack of information.
- The bigger the operation grows, the better it works: the diversity of profiles smooths the consumption curve and increases the surplus valuation rate.
