The problem being Ineffective Clean Energy Claims happening today and this problem Today, we face the challenge of ineffective clean energy claims. This problem could be fixed using Granular Certificates (Time-Stamped Energy Attribute Certificates).

Refer to the Granular Accounting in GHG Protocoland EnergyTag’s Blog on the Feasibility of Granular Certificates and Getting Started with EnergyTag for detailed explanation on the problem and its solution.

The figure above shows the overview of all the roles for the Granular Certificate Scheme under The EnergyTag Scheme Standard. The process of energy flows physically from Producer to Consumer and data flow from GC issuer/Consumer to Matcher to Claim verifier is self-explanatory in the figure above.

EnergyTag Configurations Overview

  • Configuration #1 - GC Scheme evolves out of EAC Scheme: the GC Scheme is an evolution of an existing EAC Scheme such that thecurrently operating EAC Issuing Body evolves into a GC Issuer, 

  • Configuration #2 - GC Scheme supplements EAC Scheme: the GC Scheme is an extension of an existing EAC Scheme and is managed by verified and approved third parties. Tasks and responsibilities related to the GC Scheme are performed by third-party entities in compliance with the rules and oversight of the existing EAC Scheme and EAC Issuing Body, and .

  • Configuration #3 - the GC Scheme is based on Canceled EACs: this GC Scheme enables GC Issuance where the EAC Issuing body does not oversee the coordination with GCs for the same production. Instead, the GC Issuer takes such coordination upon itself. This involves canceling GCs upon their Issuance, for the same beneficiary as the beneficiary of the associated EACs for the same represented energy.

(blue star) List of Crucial Attributes

  • Energy Carrier (always Electricity).

  • Unique identification numberIdentification Number.

  • Date when the Production Device became operational.

  • Production/storage discharge interval, which shall be a maximum of one hour.

  • GC Issuance date-stamp.

  • Source of produced energy.

  • Technology used to produce energy.

  • Name of the Production Device.

  • Unique ID of the Production Device (if available).

  • Capacity of the Production Device.

  • Country/region of Issuance.

  • Geographical location of the Production/Storage System that released the energy for which the GC is Issued (including zip code/postcode, street, city and country, and/or GPS coordinate). Where available, GPS coordinates shall be stated.

  • Wh as the base unit rather than a multiple (Base unit: Wh (not kWh, MWh, etc.) unit.

  • Volume of energy Energy production represented  volume (i.e. face value of the certificate) rounded down to the nearest Wh whole number.

  • Identity of the GC Issuer.

  • Whether it is Issued from production or released from storage.

  • Whether or not it can be used to inform consumers of the origin of the energy they consume (i.e. Disclosure).

  • Whether or not it has been Issued following Energy Carrier conversion or release from energy Storage.

  • Configuration the GC is issued (i.e. Config-1,2 or 3).
