The Spanish biomethane stack in 2026
Spain transposed RED III through Real Decreto 1085/2024, which sets out the national sustainability framework for biomethane, the gdogas.es registry operated by ENAGÁS GTS as the system operator, and the rules for the Ola 1 auctions. For a producer or trader operating in Spain, the practical compliance stack now includes: ISCC-EU or REDcert-EU as the voluntary scheme proving Article 30 compliance; gdogas.es as the national GoO registry; UDB submission once the Spanish portal goes live; and Ola 1-specific reporting for any production subscribed to the auction.
GooClear was built specifically against this stack. The mass-balance ledger is RD 1085/2024 aligned, the gdogas.es bridge is direct (not via the AIB hub for intra-Spain trades), Ola 1 reports are pre-formatted, and UDB submissions follow the Spanish schema as published.
