Today, we face the challenge of ineffective clean energy claims as consumption is matched to production annual and often from places where electricity cannot even be delivered. Granular Certificates (i.e GCs or T-EACs), revolutionize energy certificates by telling us the time of production, enabling matching of consumption with clean power production by the hour.

This is next frontier of clean energy sourcing and will be enabled by time-stamped Granular Certificates. Robust empirical research from the International Energy Agency, Princeton University, and MIT supports this approach and its various benefits:

• Enables consumers to drive deep decarbonization of the grid – every hour.

• Enables the production of clean products, like hydrogen, without any fossil reliance.

• Provides more transparency by linking production to consumption in ‘real-time’.

• Supports storage and flexibility by providing a new price signal.

• Facilitates better risk management by avoiding volatile fossil-based electricity pricing.

The illustration below shows us how much more transparent GCs are.

Definitions of Roles

• Producer: The owner of a Production Device which is valid for GC Issuance. 

• Granular Certificate Issuer (GC Issuer): A Granular Certificate Issuer is an organization responsible for the administration of the Granular Certificates within a Domain for an Energy Carrier, ensuring the avoidance of Double Counting of the Attributes represented by the Granular Certificates it administers throughout their lifetime.

• Consumer: The final beneficiary of GC/EAC cancellation and potentially the user of associated consumed energy. 

• GC Matcher (or GC-Consumption Matcher) (or Matcher): An organization that matches the Attributes of canceled GCs to a specific quantity of energy consumption of a specific Consumer/Supplier, with a view to determining the content of a GC Matching Claim.

• Claim Verifier (or GC Claim Verifier): An organization checking that Granular Certificates (GCs) are canceled against the energy consumption measured at one or a group of multiple Consumption Points in compliance with the Matching rules in this standard and the guidelines in the GC Use Case Guidelines.

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.

• Configuration #3 - 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.

Matching and Claim Verification Explained

• GC Matching (or Granular Matching or Matching): Allocating Attributes of canceled GCs to a corresponding quantity of consumed energy, for well-specified Matching Features.

• Temporal Matching (or GC Temporal Matching: Associating the period of time during which energy is produced or stored and which has been recorded on the GC at its Issuance with the corresponding time at which the GC is canceled and the energy is consumed. The time interval is equal to or less than 60 minutes and evidence of energy production and consumption is provided by GCs.

• Geographical Matching (or GC Geographical Matching): Associating the geographical location of energy production or storage which has been recorded on a GC at its Issuance, with the geographical location of energy consumption and for which the GC is canceled. For example, Geographical Matching may take place within physically interconnected zone(s) or Bidding Zone(s).

• GC Matching Claim (or Matching Claim): A statement by a Consumer or Supplier of energy regarding the proportion of their consumption being matched to GCs, and the resulting Attributes allocated to this consumption.
