KEPCO, Japan

Peer-to-Peer solar power and REC trading Peer to peer energy and REC trading with Kansai Electric Power Co (KEPCO)

Client summary

Phase 1 provided communities with cheaper energy systems to offset existing energy costs and allowed generating customers to monetize their renewable energy investments by selling their excess energy peer-to-peer.

In the second Phase, KEPCO used Power Ledger’s platform to create, track, trade and provide a marketplace for the settlement of renewable energy credits or non-fossil certificates, generated by rooftop solar systems.

How the technology works

In Phase 1 KEPCO shared meter data from 8 participants at the chosen site in Osaka City, Japan.

In Phase 2 KEPCO shared meter data from 8 participants and we aggregated the generated energy into kWh to be tokenised on our renewable energy credits marketplace. This marketplace provides the framework for providing KEPCO’s RE100 customers the ability to use non-fossil certificates against RE100 claims. RE100 is a global initiative led by international non-profit The Climate Group in partnership with global disclosure network CDP.

Power Ledger will provide KEPCO access to the Power Ledger trading platform to facilitate and monitor energy trading between participants to increase the incentive for the development of renewable distributed energy resources (DERs).

We identified there were additional opportunities to build on our original successful trial with Power Ledger to create an innovative business model for P2P energy trading between participants at houses, businesses and energy aggregators in Japan.
