European Energy Certificate System

From Open Risk Manual


The European Energy Certificate System (EECS) is a commercial European framework for issuing, holding, transferring and otherwise processing EU energy certificates. It offers a framework for cross border harmonisation of Guarantee of Origin and similar certificates.

An EECS certificate is an electronic certificate that is uniquely identifiable, transferable and tradable and it encloses information on the source of the energy and its production method.


The EECS was developed by the Association of Issuing Bodies to provide a regulated platform for Renewable Energy Guarantees of Origin, as proposed by the Renewables Directive which supports Directive 2009/72/EC (the Internal Electricity Market Directive).

EECS builds upon the concept proposed by the Basic Commitment of the Renewable Energy Certificate System (RECS) and supports all types of electricity, regardless of source or production technology.
