Nitto Kogyo Corporation (Nitto Kogyo) and Shizen Connect Inc.(Shizen Connect), which provides a VPP *1 platform, will participate in the Ministry of Economy, Trade and Industry’s “FY2023 Demonstration Project for Further Utilization of Distributed Energy Resources” (DER Aggregation Demonstration Project), in which they will conduct a demonstration project to build a VPP that contributes to power grid stabilization by utilizing Nitto Kogyo’s EV Battery Reuse System.

The project will utilize Nitto Kogyo’s environmentally friendly “Industrial Solar Self-Consumption Battery System”, installed at Nitto Kogyo’s Kakegawa plant, and Shizen Connect’s proprietary aggregate energy management system (EMS) Shizen Connect, which utilizes IoT technology and artificial intelligence (AI) to remotely control the charging and discharging of storage batteries. By remotely controlling the recharge and discharge, Demand Response (DR)*2 will be conducted within the framework of the DER Aggregation Demonstration Project to verify the technical feasibility of control for the balancing market (Replacement Reserve for FIT). 

Shizen Connect will continue to contribute to the realization of a decarbonized society together with leading companies in various fields.

■VPP image

*1 Virtual Power Plant (VPP) is a generic term for digital technology that collectively controls distributed power sources (power generation facilities, storage batteries, EVs, etc.) and demand facilities as if they were a single power plant.
*2 Demand response (DR) is the process of changing the pattern of electricity demand by allowing consumers to manage their electricity use wisely. This helps to balance the supply and demand of electricity.

■Demonstration overview

EMS Shizen Connect   https://www.se-digital.net/ (Japanese website) 
Shizen Connect is an aggregation energy management system (EMS).  It can provide  individual control for storage batteries and EV chargers, control for microgrids connecting multiple buildings with their own private transmission lines, as well as control of VPPs for large scale energy resources. Individual control and VPP control tended to be separate, but Shizen Connect provides a one stop service allowing energy resources to be used with multi-purpose, which also improves economic efficiency. The system can be adapted with any equipment supplier, allowing energy resources to be chosen freely without relying on a certain manufacturer.

Nitto Kogyo Industrial Solar Self-Consumption Battery System
The Industrial Solar Self-Consumption Battery System is an industrial solar energy storage system for self-consumption that utilizes the reuse of batteries from electric vehicles. Battery reuse reduces CO₂ emissions from the manufacturing process and reuses resources such as rare metals, creating a virtuous cycle.
