Issue, track, and retire timestamped Granular Certificates (GCs) that enable precise 24/7 carbon-free energy matching and impact reporting. Built on EnergyTag standards for complete transparency.
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.
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.
Align production and consumption in real time for verified 24/7 carbon-free energy claims.
Calculate avoided emissions using long-run marginal rates for emissionality strategies.
Use STARs to time-shift energy attributes, unlocking the full value of battery assets.
Seamlessly connect with existing registries worldwide through Configuration 2.
From corporate giants pursuing 24/7 CFE to developers maximizing project returns, the Granular Registry adapts to your needs.
Achieve verifiable hourly matching and impact reporting for your sustainability goals.
