Guaranteeing the origin of European energy


AIB - "guaranteeing the origin of European energy"

The purpose of the AIB is to develop, use and promote a standardised system: the European Energy Certificate System - "EECS".

EECS is based on structures and procedures which ensure the reliable operation of international certificate schemes. These schemes satisfy the criteria of objectivity, non-discrimination, transparency and costs effectiveness, in order to facilitate the international exchange of guarantees of origin.

In order to further facilitate this, the AIB operates an inter-registry communications Hub.

The AIB also provides a knowledge centre for energy certificate authorities across Europe, providing and sharing advice and guidance.


Italian GO's

AIB Members cooperated in resolving the case of Italian non-RES GOs

Late in 2019, the AIB discovered that during 2014-2019 some Italian production devices had received GOs for renewable energy which, while they meet Italian criteria for renewable energy, do not meet the corresponding EU criteria. The GOs were issued for electricity production from synthesis gas, which is considered by Italian legislation to have been produced from renewable energy, regardless of the source of the energy from which it was actually produced.

In a process facilitated by the AIB reviewers, the Italian issuing body GSE and other AIB Members agreed a common way forward. This involved replacing GOs for non-renewable energy which have been exported from Italy by GOs for bona fide renewable energy. GSE agreed to replace the nearly two million GOs still residing in the GO registries of other countries by new Italian RES-GOs which were not sold at its periodic GO Auctions. Furthermore, GSE drafted a “GO Swap Agreement” to virtually replace the close to eight million cancelled and expired “non-RES” GOs held in other national registries with these renewable GOs.

The way forward was agreed by the AIB on 25th April 2020. The Italian reviewers will monitor the rectification process, and the AIB audit framework was strengthened to prevent such rare breaches of the EECS system in the future. Throughout the process, it was of utmost importance for AIB to seek mutual resolution in a cooperative manner, whilst guaranteeing the reliability of the European GO and electricity disclosure system.

FaStGO - Facilitating Standards for Guarantees of Origin

The FaStGO project provides expert advice to the European Commission DG ENER, based on the terms of Reference N° ENER/C1/2019-517: “Technical support for RES policy development & implementation. Establishing technical requirements and facilitating the standardisation process for guarantees of origin on basis of Dir (EU) 2018/2001.”

You are welcome to help upgrading the EN16325 standard on guarantees of origin for energy. See how on the FaStGO project sites.
