ESB announces pilot with Granular Energy to help organisations reporting on Guarantee of Origin energy certificates
The game-changing pilot for Guarantee of Origin certificates will make hourly matching for green energy feasible.

Today, ESB’s Venture Innovation Team, X_Site, in partnership with Granular Energy has successfully completed the first phase of a pilot integration that has made generating hourly matched green energy reports feasible for several sample commercial customers.
To support targets that address climate change, large companies increasingly seeking a guarantee of green energy from their energy suppliers before switching. These guarantees of origin energy certificates (GOOs) are matched on an annual or monthly basis so it can often prove difficult for energy companies, and their customers, to report on their green energy usage on an accurate basis.
As part of this pilot, data from ESB’s Carnsore wind farm was directly matched to test customers hourly consumption, demonstrating that the data could be matched accurately and reported immediately to customers. Working in partnership with Granular Energy – winners of the ESB supported Free Electrons global accelerator programme in 2023 – the pilot exploring the potential of providing a new platform for GOO certificates which will benefit ESB’s customers and internal trading teams.
Geraldine Moloney, Head of New Ventures at ESB, said: “We are committed to making it easier for commercial customers to track their green energy reporting – a crucial step for many in meeting important climate targets – and this innovative project demonstrates our continued commitment to finding innovative solutions to enable the delivery of such solutions. We are delighted with the results of our pilot with Granular Energy into the future and I am excited to see how this can help support the delivery of our own Net Zero by 2040 strategy.”
Toby Ferenczi, CEO at Granular Energy, said: “ESB is one of the world’s most innovative energy utilities. We’re excited to work on this project because we believe it could play a part in resolving some of the key challenges facing the Irish energy system, such as how to meet the growing demand for electricity from industries such as data centres or green hydrogen without this leading to an increase in carbon-emissions.”

Carbon-Free Chronicles April 2026: The essential round-up of news and reports relating to hourly transparency
April brought the debate on clean energy procurement off the page and into the room. On 24 April, we co-hosted Next-gen Electricity Procurement with CMS in London, bringing together energy buyers, suppliers, and market participants for a morning of panels on Scope 2 reform, next-gen portfolio management, and the future of licence-exempt supply in the UK. The conversations were sharp, and the appetite for clarity on where the market is heading was clear. Beyond the event, April saw the emissions accounting debate intensify, new research quantifying just how much program design matters in carbon-free energy (CFE) procurement, the European Commission signalling its direction on time-based guarantees of origin (GO), and the UK's AI data centre energy planning revealing some uncomfortable contradictions. Here is what has been on our radar.
