Enhance Your Existing RECs with Time, Location, and Other Attributes
The Granular Registry issues, tracks, and retires timestamped Granular Certificates (GCs) that enable precise 24/7 carbon-free energy matching and impact reporting. With seamless integration across global registries, it delivers transparent, compliance-grade infrastructure for corporate buyers, utilities, and policymakers to accelerate the clean energy transition.
Why Traditional Energy Tracking Isn't Enough
For years, companies and utilities have relied on annual Renewable Energy Certificates (RECs) to claim green power. But in today's dynamic grid, this approach creates gaps: it doesn't account for when energy is produced or consumed, leading to mismatched claims, overlooked emissions, and missed opportunities for real decarbonization. As stakeholders demand proof of 24/7 carbon-free energy and true environmental impact, outdated systems hinder progress, increase risks of greenwashing, and slow the transition to a cleaner planet.
Introducing the Granular Registry: Precision Power for a Net-Zero World
The Granular Registry is an open-source platform that transforms traditional RECs into timestamped Granular Certificates (GCs). Built on global standards like EnergyTag, it issues, tracks, and retires certificates with hourly precision, embedding data on time, location, and carbon impact. Whether you're shifting energy with storage or matching corporate loads, our registry ensures verifiable, scalable tracking—empowering buyers, developers, and operators to achieve credible sustainability goals without complexity.
