New Battery Storage Facility in Sendai

Nippon Chikudenchi Co., Ltd., in collaboration with Digital Grid Co., Ltd. and Remixpoint, has announced the official launch of the "NC Sendai Aoba-ku Kamiaiko" battery storage facility. This project aims to address the increasing fluctuations in energy supply and demand due to the rising adoption of renewable energy sources. On June 23, 2026, this facility will officially start operations in the supply-demand adjustment market, contributing to the stability of the local energy grid in Sendai, Miyagi Prefecture.

Overview of the Facility

The NC Sendai Aoba-ku Kamiaiko facility is a systemic battery storage project developed through a joint fund set up by Nippon Chikudenchi and Remixpoint. Nippon Chikudenchi is responsible for the development and operation of the facility, while Remixpoint handles business management and oversight.

This facility has a battery capacity of 1,998 kW and can store 8,146 kWh of energy, utilizing cutting-edge technology from TMEIC and CATL. The main aim of this facility is to absorb and smooth out fluctuations in renewable energy outputs, thus ensuring a stable electricity supply for the region. It represents a model case for demand-supply adjustment projects using grid batteries.

Background and Importance

As Japan sees a significant increase in renewable energy usage, managing the fluctuations in electricity supply and demand becomes a critical issue in the nation’s energy infrastructure. Batteries serve a vital role by bridging the temporal gap between generation and consumption. They support the stabilization of the grid and add to the sophistication of the electricity market. This collaborative project involves:
- Nippon Chikudenchi: Overall development, operation, and on-site management.
- Digital Grid: Utilizing its digital platform for aggregation and facilitating entry into the supply-demand adjustment market.
- Remixpoint: Business management of the storage facility including contract management and regulatory liaison.

This synergistic approach aims to create a sustainable energy adjustment model that integrates technology, operations, and market dynamics.

Future Plans

Looking ahead, Nippon Chikudenchi intends to expand battery storage facilities nationwide. They plan to establish a regional energy model that combines the wholesale market (JEPX), supply-demand adjustment market, capacity market, and disaster energy support initiatives. By collaborating with Digital Grid and Remixpoint, the company seeks to further harness renewable energy and contribute to a decarbonized society.
