Granular Energy becomes accredited issuer of Granular Certificates under EnergyTag

Granular Energy is proud to announce our accreditation as an official issuer of Granular Certificates (GCs) under Configuration #3 of the EnergyTag standard. This milestone reinforces our commitment to driving the global shift to 24/7 carbon-free energy (CFE) by enabling trusted, auditable hourly matching of clean energy in regions where such tracking was previously unavailable.

Why this matters

Today, most clean energy claims are based on annual or monthly Energy Attribute Certificates (EACs), which offer limited transparency about when renewable energy was actually consumed. This time mismatch undermines efforts by corporates, suppliers, and regulators striving for more rigorous 24/7 carbon-free energy goals.

That’s where Configuration #3 GCs come in. These certificates allow for auditable hourly tracking in markets where formal Issuing Bodies don’t yet offer sub-hourly or hourly certificates. It fills a critical market gap, ensuring that 24/7 CFE claims are verifiable, credible, and not subject to double counting.

What our accreditation enables

With this accreditation, Granular Energy can now:

  • Issue verified hourly GCs in regions lacking official hourly EACs, allowing energy buyers and sellers to participate in the 24/7 CFE transition globally.
  • Retrofit existing contracts, from PPAs to green tariffs, with time-stamped certificates that meet EnergyTag standards.
  • Enable compliance and leadership in sustainability claims, helping corporates align with upcoming regulatory shifts and investor scrutiny.

A foundation for global standardisation

Beyond a technical accreditation, this is a foundational step toward building a globally interoperable system for time-based energy tracking. By supporting EnergyTag’s Configuration #3, Granular Energy is helping set a precedent for trustworthy hourly claims in every market, no matter how advanced its current certificate system.

“24/7 carbon-free energy must be grounded in real data, not assumptions. Our accreditation ensures that every claim backed by Granular Certificates is backed by auditable proof. It’s about enabling a cleaner, smarter grid and the credibility needed to accelerate investment.”

— Toby Ferenczi, Co-founder, Granular Energy

We’re excited to work with our partners and the EnergyTag community to continue advancing hourly energy tracking and market transparency.

Carbon-Free Chronicles March 2026: The essential round-up of news and reports relating to hourly transparency

March was a month of accelerating signals. Major investors are calling for a fundamental update to Scope 2 accounting and the EU's Carbon Border Adjustment Mechanism entered its full compliance phase. The direction of travel is consistent: clean energy claims need to be grounded in physical reality, matched by time and location. Here is what has been on our radar this month.
