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

It was discovered recently that under Italian legislation, three production devices have received guarantees of origin (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 from fossil origin, which according to the CIP6 support system is assimilated to renewable energy. These GOs have been auctioned by the Italian GO administrator GSE and have circulated within the AIB community for a number of years, without the knowledge of the AIB or its members.

Issuing of these GOs has now ceased and further exports from GSE have been blocked. GSE is cooperating with the relevant issuing bodies to replace the GOs in question, with valid GOs from renewable sources. AIB has thoroughly investigated the issue and is considering further measures against GSE. Moreover, AIB is strengthening both its internal audit practices and its hub functionalities to improve detection and resolution of such rare breaches of the EECS framework.

For further information, please contact your national issuing body - member of the AIB.
