Altenex Energy supports EnergyTag to help build a market for hourly energy certificates

The EnergyTag Standard and Guidelines for Granular Certificates (GCs) helps drive international recognition of GCs as a robust and tradable instrument that, for the first time, enables consumers to choose the source of their electricity consumption on an hourly basis.

Altenex Energy is one of many organizations that supports EnergyTag, along with some of the world’s largest renewable energy producers and consumers, grid operators, startups, and key organizations within the energy certificates market like UN Energy, Google, Microsoft, Mitsubishi Electric, and FlexiDAO.

EnergyTag is an independent, non-profit, industry-led initiative to define and build a market for GCs that allows energy users to verify the source of their electricity and carbon emissions in real-time. The central purpose of GCs is to align electricity traceability more closely with the physical reality and real-world availability of clean energy sources.

Some of the benefits provided by GC markets include:
  • An opportunity to improve public perception of clean energy claims
  • Better matching of clean energy supply and demand
  • The enabling of more granular carbon accounting methodologies
  • The creation of an additional price signal for grid decarbonization technologies such as energy storage
  • Helping buyers displace carbon-emitting generation at specific times and locations to maximize Avoided Emissions
Why does it matter?  

To date,  energy consumers have been unable to choose their energy source on an hourly basis, as current Energy Attribute Certificates (EACs) are not time-stamped. EnergyTag is seeking to address this by establishing and building a market for timestamped, or ‘granular’ energy certificates (GCs) that enable hourly and sub-hourly consumer electricity source choice.

Some consumers may source GCs from production devices that temporally and geographically match their consumption points (e.g., 24/7 Carbon-Free Energy, or CFE), while others may source GCs to maximize Avoided Emissions, even if there is no link to their consumption.

Use Case examples:
  • Temporal matches: To match the time interval of consumption and the time interval of production of the corresponding energy attributes, including how storage devices may participate in GC schemes to provide clean electricity at times of scarcity.
  • Geographical matching: To drive the supply of local clean energy, temporal matching implies a degree of more precise geographical matching.
  • Avoided Emissions: To help demonstrate the displacement of carbon-emitting generation at specific times and locations to maximize Avoided Emissions, even if this is not linked to consumption.
The EnergyTag Standard and Guidelines

The GC Scheme Standard provides the first version of the criteria that those implementing GC schemes must meet to prove – through a third-party audit – that they are “compliant with the EnergyTag Standard.”
The EnergyTag’s Guidelines provide the first framework for the use of GCs. While the included Use Cases are not mandatory, these Guidelines must be followed where the consumer wishes to prove that their GC use is “aligned with the EnergyTag Guidelines” through a third-party independent audit. The Guidelines also provide EnergyTag’s initial considerations on temporal greenhouse gas calculations that are not yet considered guidelines.
