erex Co., Ltd.*1, Sharing Energy Co.Ltd.*2 and Power Ledger Pty Ltd*3 will launch a collaborative demonstration experiment of a next generation power system that enables “Peer to Peer (P2P) power trading”, a person-to-person renewable energy transaction by utilizing blockchain technology in the Kanto area from October 2019.

■Purpose of the demonstration
With the spread of solar power generation and storage batteries, Japan’s power supply system is shifting from the traditional large-scale, concentrated power supply system to a decentralized system in which individuals and companies own the power sources.
The purpose of this demonstration experiment is to verify the effectiveness of an interactive and autonomous power supply system in which consumers who own decentralized energy trades electricity directly with other consumers in the future.
■Demonstration contents
Utilizing Power Ledger’s blockchain technology, some consumers (prosumers) own solar power systems, such as “Share Denki”(meaning to share electricity), a third-party ownership model for solar power systems deployed by Sharing Energy.
We will examine the feasibility of P2P power trading, in which the renewable energy generated by these consumers (prosumers) will be sold to erex Group’s electricity consumers.
The demonstration experiment will utilize FLET’S Miruene 1 manufactured by NTT EAST in order to understand the amount of electricity purchased and sold by the smart meters of the households cooperating in the demonstration experiment on a real-time basis.
This service has a function for distributing electric power data (B-route data) and is able to get the amount of electricity consumed per minute in a minimum of 5 minutes.
Therefore, it is possible to collect the necessary power data for this demonstration experiment.
Through this initiative, we will create a system that makes effective use of decentralized energy in our society, including post-FIT power, which will come to market after November 2019.
