RaYSun, catalyst for energy communities in Belgium
Whether you’re already familiar with how an energy community works or starting from scratch, we’re here to guide you.
We help individuals, businesses, and public bodies regain control of their energy by creating local, sustainable, and collaborative energy communities.
For those looking for an easy start, we have developed turnkey solutions — including Energilia, as well as dedicated and autonomous community models. Thanks to these simple, fully supported models, you can join or establish an energy community without managing technical and administrative complexities.
RaYSun handles everything: design, management, energy sharing, and on-site support.
Unlike large utility providers, our approach is collective, rooted in local territories, and centered on transparent and accessible sharing solutions.
Join a future-oriented model that is more equitable, local, and responsible.

Our three energy community models
At RaYSun, we believe everyone can take an active role in their own energy transition. That’s why we offer three types of energy communities, tailored to your level of involvement, needs, and goals.
Energilia
Turnkey solution
Ideal for a simple start.
Want to join an existing community without complexity, to valorize your surplus or benefit from other members’ solar energy?
Whether you’re a producer, consumer, or prosumer, Energilia offers strategic advantages: more stable energy, reduced bills, and full control over your consumption. Joining this community shields you from market volatility and energy monopolies, while actively participating in local green electricity production and consumption. With Energilia, you choose a sustainable, economical, and resilient model.

Our projects

SAK (Switzerland)
RaYSun conducted an exploratory study on energy communities for the Swiss grid operator SAK, in partnership with Urbio. The project, completed in April, allowed analysis of the potential for energy sharing in three municipalities in anticipation of new legislation coming into effect in 2026. This mission marks RaYSun’s first active presence in the Swiss decentralized energy market.
Brasserie du Bocq
Brasserie du Bocq launched its local energy community with the help of RaYSun and Soltis. Thanks to a system for sharing solar energy between two buildings with different consumption profiles, the brewery consequently reduces its energy costs and dependency.
In the future, staff and neighbors of the brewery will potentially be able to become consumer-members of this energy community.
Fico Energy
RaYSun supported FICO in creating FICO Energy, a structure dedicated to investing in renewable infrastructure (solar panels and charging stations) to develop its own energy communities. Two sites in Aalst and Haaltert were equipped with 964 photovoltaic panels, representing a capacity of 421 kWp. The electricity produced is used by several tenants (BMW – MINI Meerschman, ZTE Corporation, PPP, Zone de secours Sud‑Est) as well as by FICO’s headquarters, contributing to the sustainability of its real-estate portfolio and ensuring access to green, local energy.
Saint-Lambert
RaYSun implemented an energy-sharing system in a Brussels apartment building, allowing tenants to directly consume the green electricity produced on-site. This simple solution, quick to install and without grid fees in Brussels, optimizes energy costs while facilitating access to local, sustainable energy.
Don Bosco
Thanks to a photovoltaic installation carried out with Soltis, Don Bosco School now produces its own green electricity. Through the Energilia Brussels community, surplus energy is shared with other members such as the Quartier Libre cooperative. Up to 203 MWh of green electricity are thus redistributed each year, reinforcing energy solidarity in Brussels.
