A Guarantee of Origin, or GO, is a European energy attribute certificate that documents the source attributes of electricity generation. One GO generally represents one megawatt-hour from an eligible production asset.
GOs are used for European renewable electricity documentation.
A GO can carry information such as production technology, generation period, issuing domain, and the production asset. Buyers use GOs as part of renewable electricity sourcing and market-based Scope 2 documentation.
GOs are distinct from I-RECs, North American RECs, UK REGOs, and other certificate systems. The relevant system depends on the market, claim, and reporting need.
GreenPowerHub supports GO workflows across market coverage, RFQs, marketplace activity, price context, trading workflows, and documentation.
What to check next
- Use GOs for European certificate questions.
- Check country, issuing domain, volume, vintage, technology, and delivery timing.
- Do not treat GOs, I-RECs, RECs, and REGOs as interchangeable without market review.
- Keep redemption or cancellation documentation connected to the buyer and claim.
