AIB-Hub Connected refers to national registries that follow the European Energy Certificate System (EECS) standards and are connected via the AIB Hub - registries with this status can transfer Guarantees of Origin (GOs) electronically through the hub. In practice, that means buyers can procure and cancel Energy Attribute Certificates across borders without logging into each country's registry separately.

For companies doing market-based reporting for Scope 2 under the GHG Protocol, AIB-Hub connectivity is what confirms a certificate is legitimate within AIB Market Boundaries and hasn't been counted twice. Compliance teams rely on this status for verified documentation backing their renewable energy claims.

One thing to watch: Icelandic GOs carry AIB-Hub Connected status, but Iceland has no physical grid link to mainland Europe. Some corporate buyers and auditors treat that differently. The related adjective AIB Grid-Connected adds a market-driven physical interconnection requirement on top of the EECS registry standards, and that distinction matters when sourcing for stricter procurement policies. Each country runs its own registry with its own procedures. Certain platforms like Soldera handle cross-border GO transactions through a single interface via integrations, so you don't need accounts for multiple national systems yourself.
