We are pleased to share a case study from EnergyTag featuring a project led by us at D-Sharing Co., Ltd.:
In 2024, under a government program by the Ministry of the Environment Japan, we conducted a pilot demonstrating half-hourly matching of locally generated solar power with EV charging demand within the same community.
From a technical perspective, the project tested a model in which distributed solar generators created and issued pseudo granular energy attribute certificates (GC-EACs), and subsequently sold these certificates to EV charging users on a time-matched basis. This enabled a practical demonstration of a group-based, time-resolved matching mechanism built on granular certificate concepts.
This initiative is positioned as the first government-led implementation of hourly matching in Japan, and is also referenced as such in official government communications. We consider it a meaningful milestone and are proud to have contributed to this development.
Building on this, in 2025, we at D-Sharing Co., Ltd. conducted a further feasibility study—also supported by the Ministry—examining three key dimensions: (i) the technical validity of the model, (ii) its economic viability and scalability, and (iii) the appropriate design of policy and regulatory frameworks.
As the enabling conditions in Japan continue to evolve, we look forward to contributing to the development of a market framework for granular certificate trading.
