Kansai Electric Power Company conducted a pilot demonstration at EXPO 2025 Osaka to explore sub-hourly carbon-free energy (CFE) matching within the Japanese power system. Solar generation data from multiple sites across the Kansai region was matched against electricity consumption at the EXPO venue on a 30-minute basis using metered operational data, with matching results recorded on a blockchain-based system for transparency and traceability.
The pilot did not use a conventional renewable energy tracking instrument or EAC system. Instead, it explored direct time-based matching using operational data following the principles of the EnergyTag Granular Certificate (GC) Scheme and Matching Standard, including sub-hourly temporal matching and same-grid geographical matching. However, the project itself was not verified by an EnergyTag / Accredited GC issuer.
The pilot project reflects growing interest in 24/7 Carbon-Free Energy and evolving discussions around hourly and sub-hourly electricity matching corporate energy accounting.
Demonstrated practical sub-hourly matching of renewable electricity generation and consumption using operational metered data.
Explored blockchain-based recording to improve transparency and traceability of matching outcomes.
Showed how utilities can support more time-based clean electricity tracking approaches as international accounting discussions continue to evolve.
Reflects growing momentum around granular electricity accounting and 24/7 Carbon-Free Energy approaches in Asia-Pacific markets.
