Association of Issuing Bodies


The Association of Issuing Bodies - the AIB - promotes the use of a standardised system, based on harmonized environment, structures and procedures in order to ensure the reliable operation of international energy certificate systems. The standardized system is known as EECS - the European Energy Certificate System - and is set out in "The EECS Rules" and its supporting documents.
Of the 28 countries of the European Union, 18 are now active members, along with Norway and Switzerland. Since 2001, more than three billion 1MWh certificates have been issued, of which 2,859 million have already been used to guarantee to consumers the origin of the renewable energy they have purchased. In 2016, more than 531 million certificates were issued, and 387 million of these were cancelled.
The work of the AIB is of relevance to all electricity customers, as the Guarantee of Origin is a cornerstone of providing reliable disclosure information on the origin of electricity supplied to consumers.
