Guarantees of Origin

Certainty of consuming renewable electricity

The Guarantee of origin (GoO or GO) is defined in art. 15 of the European Directive 2009/28 / EC and subsequent amendment RED II, and is the only recognized tool in the European Union, Norway and Switzerland for tracing the renewable source of the electricity produced. In order to claim the consumption of renewable electricity, the end consumer must buy a Guarantee of Origin.

How does it work?

The competent national authority (Issuing Body) issues the Guarantees of Origin electronically for each MWh of electricity produced from renewable sources. Each GoO or GO is exchangeable and transferrable between operators in those countries that adhere to the system of European Guarantees of Origin through the AIB Hub.

To prove the consumption of 1 MWh of renewable electricity, the GO must be cancelled in the relevant national register, in the name of the final consumer or for fuel mix disclosure purposes.

Each Guarantee of Origin within the European Energy Certificate System (EECS) has a validity of 12 months, this means that from the moment the MWh of renewable power is produced and the corresponding GO is issued, the certificate can be transferred and cancelled only within 12 months. After this period, the GO expires and falls automatically in the residual mix of the country in which it is located at that moment.

The renewable installations falling under this scheme, or the certificate itself, can carry a Label that certifies additional quality and environmental standards. Such Label guarantee, for example, a particular attention to the respect of ecosystems or the reinvestment of revenues in new renewable projects. Among these Labels we find EKOEnergy , Naturemade, OK Power, TÜV NORD, and many others.

Furthermore, the Guarantees of Origin, together with the I-RECs and RECs, are the main tool for documenting and tracking the consumption of electricity from renewable sources in the new version of the Greenhouse Gas Protocol Scope 2 Guidance.
