Cross-border Guarantee of Origin (GO) management is very fragmented within Belgium. That's because the nation splits the renewable GO system along its constitutional lines, effectively creating four independent registry systems - a unique case within Europe.
There is:
- a Flemish registry operated by the Flemish Utility Regulator VREG
- a Brussels‑Capital registry operated by BRUGEL
- a Walloon registry where SPW Énergie issues GOs for installations in Wallonia
- and a federal registry covering offshore generation in the Belgian part of the North Sea that is overseen at federal level via CREG.
See this handy map below: it introduces Belgium's power system at a glance, weaving together how electricity is generated, where installations cluster, and how those flows are tracked across the grid and through GOs.
In short, Belgium is unusual in the AIB context because it runs four linked GO domains that mirror its institutional split. Operationally the registries behave alike because they follow EU law (REDII and REDIII) and AIB practice, yet each domain bakes in its own processes.
For instance, in Flanders, device applications are initiated via "production registrars" such as Fluvius for PV installations and the Flemish Energy Agency for other technologies, then VREG issues GOs into the electronic V‑platform. Trading can occur bilaterally within the platform or cross‑border via the AIB Hub, and suppliers must cancel GOs within 12 months to substantiate green supply claims in their annual disclosure and in VREG's Green Check tools.
At sea, federal offshore producers obtain GOs under CREG's framework and related royal decrees, then suppliers cancel those GOs in regional disclosure processes where end‑customers reside, which is why offshore certificates show up prominently in Walloon disclosures as a source category.
Belgian GO Price history exists from official sources
Belgium does not publish a single national GO price index, yet Wallonia's administration releases official monthly, quarterly and annual price series that are widely referenced for Belgian context. The Walloon GO market page links directly to downloadable files for 2020, 2021, 2022 and 2024 and explains the methodology, including the fact that many transactions occur at zero or unspecified price when GOs are bundled with support instruments in contracts. These files and the annual market report provide the clearest government‑sourced view of price history in Belgium's GO ecosystem.
Do you wish there was just one registry for Belgium?
We solved this. If you operate production devices across Belgium's four domains and want a single dashboard to manage guarantees of origin, Soldera can help. We're fully integrated with European registry systems, and Belgium is no exception. That means one account for ALL renewable energy assets and certificates across Federal, Flanders, Wallonia, and Brussels.
But it's not just a registry wrapper. We've centralized SPV management, PPA management (whether physical or virtual), and device registration all in one place, for free - no more remembering credentials to all four registries. On top of this, we'll auction your GOs with the aggregated spot and forward volumes of other producers to fetch optimal prices - the strength of better volume in action.
Consider signing up today, and we'll take care of your Belgium GO processes - no more headache.
