ReCert - Re-Certification for Granular Certificates

Granular Certificates (GCs) represent the next generation of Energy Attribute Certificates (EACs), enabling real-time energy tracking and improved transparency in renewable energy markets. Unlike traditional EACs, which cover monthly or yearly periods, GCs provide hourly or even sub-hourly data for energy generation and consumption.

Energy Attribute Certificates (EACs) are an older mechanism for tracking renewable energy consumption. However, they lack time granularity, meaning they only provide monthly or yearly tracking instead of real-time hourly data. This makes it difficult for businesses and energy buyers to match their actual consumption with clean energy production on an hourly basis. Additionally, EACs are prone to double counting risks if not properly managed, and they do not support emerging market needs for real-time energy matching and 24/7 carbon-free energy goals.
