On June 14, the Environmental Co-Creation Initiative (SII), a general incorporated association, announced the results of its adoption in the renewable energy aggregation demonstration project. Demonstration was conducted in four consortiums, and the respective consortium leaders were Japan Energy Systems (JPN), Toshiba Energy Systems (Toshiba ESS), ENERES, and Terrace Energy.

It will be adopted for the 2023 “Subsidy for Next-Generation Technology Construction Demonstration Project Expenses Utilizing Distributed Energy Resources such as Storage Batteries (Renewable Energy Aggregation Demonstration Project)” implemented by the Ministry of Economy, Trade and Industry.
This project will demonstrate control technology that combines renewable energy and distributed energy resources (DER), which is necessary for creating power generation plans and avoiding imbalances, and predicting technology for renewable energy power generation and wholesale market prices. The purpose is to increase the use of DER and create an environment in which renewable energy can be used effectively. The subsidy rate is within half, and the upper limit is 100 million yen for consortium leaders and 20 million yen for renewable energy aggregators and demonstration collaborators.
A consortium represented by JPN will demonstrate aggregation by small and medium-sized power generation facilities. We aim to establish aggregation technology and a profitable business model by demonstrating improved profitability of feed-in-premium (FIP) power sources, demonstrating improved self-consignment rate, and utilizing storage batteries.
In the last fiscal year, we carried out "preliminary verification for FIP power plant", "reduction of imbalance, determination of storage battery capacity necessary for market transactions and verification of business profitability", and "verification of effect of introducing storage battery to low-voltage power generation facility". Seven new companies will participate this year, and in addition to increasing the number of power plants to improve verification accuracy, we will work on updating the aggregation system to incorporate an "AI market unit price prediction system" that supports supply and demand adjustment market transactions.
In addition, a virtual demonstration will be conducted with the aim of achieving 100% self-consignment renewable energy with an energy mix power supply that utilizes three power sources: small hydroelectric power, solar power, and digestion gas power using sludge. We envision carbon neutrality and microgrid construction for local governments.
There are 13 companies participating in the consortium. The renewable energy aggregator is RE100 power. Demonstration partners are Yokogawa Solution Service, Edison Power, Laplace System, Aioi Nissay Dowa Insurance, Tensor Energy, Creator's NEXT, Fuso, Tokyo Century, Kunimoto Shokai, Toyokuni Seiyu, and Ricoh Lease.
In addition, a consortium represented by Toshiba ESS (8 renewable energy aggregators, 5 demonstration collaborators), a consortium represented by ENERES (2 renewable energy aggregators, 9 demonstration collaborators), and Terrace Energy. A consortium (8 renewable energy aggregators, 1 demonstration cooperator) was adopted.
