New Era forEnergy Storage in Japan

Nippon Chikudenchi Co., Ltd., a leading player in the energy storage sector, announced the establishment of a new energy storage facility named "NC Tamana Aono Storage" in Kumamoto Prefecture, set to commence operations in the demand-supply adjustment market on August 19, 2026. This initiative is a testament to the company's commitment to enhancing the stability of local power supplies and address the growing challenges brought on by the fluctuating nature of renewable energy sources.

The facility has been jointly developed through a fund created by Nippon Chikudenchi and Remixpoint, Inc., leveraging each company's capabilities to create a robust energy infrastructure. Nippon Chikudenchi is responsible for the development and operation of the facility, while Remixpoint oversees business management and oversight. This collaborative effort aims to absorb and smooth out the output fluctuations from renewable energy, providing essential support for regional electricity stability.

Facility Overview

• - Facility Name: NC Tamana Aono Storage
• - Location: Tamana City, Kumamoto Prefecture
• - Rated Output and Capacity: 1,998 kW / 8,146 kWh (Battery System by TMEIC and CATL)
• - Start Date for Demand-Supply Adjustment Operations: August 19, 2026
• - Aggregator: Digital Grid Corporation

Background to the Project

As the adoption of renewable energy expands in Japan, effectively managing the variability in power supply and demand has become a crucial issue for the country's energy system. Energy storage systems, such as batteries, are emerging as critical enablers by bridging the temporal gaps between energy production and consumption. Consequently, they serve as foundational infrastructure to stabilize the grid and enhance the electricity market.

In this project, collaboration takes on several significant roles:

• - Nippon Chikudenchi: Overall development, operation, and site management.
• - Digital Grid: Support for entry into demand-supply adjustment markets and leveraging their digital grid platform for aggregation.
• - Remixpoint: Business management and oversight, including contract management, financing, revenue management, and governmental compliance.

Through this collaboration, the aim is to establish a sustainable power adjustment model, integrating technology, operations, and market participation into a cohesive ecosystem.

Future Developments

Looking forward, Nippon Chikudenchi intends to expand its network of system-use energy storage facilities across the country. Their goals include establishing a regional energy model that harmonizes with the wholesale market (JEPX), demand-supply adjustment markets, capacity markets, and disaster relief energy support initiatives. Through collaboration with Digital Grid and Remixpoint, Nippon Chikudenchi is committed to contributing to the stable utilization of renewable energy and realizing a decarbonized society.

In conclusion, the establishment of the NC Tamana Aono Storage facility is not just a significant leap for Nippon Chikudenchi but also a vital step forward for Japan's energy landscape as it navigates the challenges and opportunities presented by renewable energy sources. This project reflects a collective commitment towards sustainable energy solutions that will benefit both the environment and local communities.
