Overview of the different energy attribute certificate systems worldwide.
An energy certificate or energy attribute certificate is a transferable record or guarantee related to the amount of energy or material goods consumed by an energy conversion device in industrial production. A certificate may be in any form, including electronic, and lists attributes such as method, quality, compliance, and tracking.
Terminology
An energy attribute certificate (EAC) can include "a variety of instruments with different names, including certificates, tags, credits, or generator declarations."[1] These certificates relate to various tracking systems worldwide.[2]
Energy certificates issued under national legislation typically provide evidence of compliance. Electricity producers, suppliers, or consumers use these certificates when required to use a specific type of energy or to qualify for financial support. Qualifying plants often produce electricity from renewable sources or high-quality co-generators.
Some examples are:
United Kingdom: Renewable Obligation Certificates (ROCs) issued under the Renewables Obligation
United Kingdom: Levy Exemption Certificates (LECs) issued under the Climate Change Levy.
Italy: Certificati Verdi
Sweden and Belgium: Elcertifikat
Most of these support schemes are national. The Climate Change Levy is a notable exception; the regulator issues LECs to electricity producers in the United Kingdom and several European countries that export to the UK.
The European Union create internationally transferable "guarantees of origin:" It provides proof to consumers of the source of their electricity, as required by Directive 2009/72/EC. Electricity suppliers use these guarantees when calculating the proportions of energy sources (fossil fuel, nuclear, etc.) in their supplied energy. Governments use them to calculate the residual mix—the blend of electricity sources produced in a country, adjusted for imports and exports.
^Renewable Energy Certificate (REC) mechanism in India is developed to create a market-based instrument to promote renewable energy.
^In April 2017, METI transformed its offset-credit scheme "J-credit system" to provide businesses with; offsetting credits and Energy Attribute Certificates (EAC) in the form of JCredits.
^Taiwan REC Standard (T-REC) In June 2017, Taiwan opened its National Renewable Energy Certification Center (T-REC Center) which issues contractual instruments. T-RECs may be used to prove the consumption of renewable electricity.
