Granular certificate matching (more broadly conceptually referred to as "granularity") pairs generation timestamps with EAC retirement intervals at sub-annual resolutions, working to ensure that renewable energy generation and EAC retirement are occurring within highly aligned timeframes (sometimes, as aligned as hourly or sub-hourly), boosting the credibility of a claim. Groups and pacts dedicated to collaborating on the topic exist: such as SEForAll and 24/7 Carbon Free Energy, fostering conversation and dialogue. Yet, whilst "hourly matching" is emerging as a discussion point and potential standard for the market to evolve into, it's not currently clear how a shift towards granularity would impact EAC price dynamics, or if market infrastructure is currently prepared for that leap (at least in the immediate future).
