APAC Factbook on Granular Electricity Accounting

1 August, 2025

This Factbook provides a concise overview of granular electricity accounting and its role in advancing 24/7 carbon-free energy (CFE) across the Asia-Pacific region. It explains how hourly matching of clean electricity can enhance transparency, strengthen the credibility of clean energy claims, improve system efficiency, and help APAC industries comply with emerging global carbon reporting frameworks such as the GHG Protocol and trade-linked regulations like the EU CBAM. Covering twelve priority markets, the Factbook offers practical insights, policy signals, and case studies to empower stakeholders in shaping resilient and future-ready clean energy systems.

Tracer l’Électricité au Pas Horaire

13 November, 2024

Rédigé par Alexandre Joly (Carbone 4), Killian Daly (EnergyTag), et Bruno Menu (Granular Energy), ce document présente l’importance d’une traçabilité horaire de l’électricité verte pour accélérer la décarbonation en France. Actuellement, les garanties d’origine sont associées à la consommation de manière mensuelle, limitant leur impact réel. Le passage à un “matching horaire” renforcerait la précision de la comptabilité carbone, la confiance des consommateurs, et faciliterait la transition énergétique en adéquation avec les nouvelles régulations européennes.

Granular Electricity Accounting: Paving the Way for India’s Clean Energy Future

23 October, 2024

India’s heavy reliance on fossil fuels has raised its share of global energy-related carbon emissions, highlighting the urgency for renewable energy in its decarbonization efforts. Granular electricity accounting can help enable this through real-time clean energy matching which enhances transparency. While a new concept, it builds on existing policies in India like the 15-minute block settlement system, FDRE and G-TAM. Addressing challenges and opportunities is crucial for effective implementation of granular electricity accounting in India.
