Launch of the NC Aoba District Kamiaiko B Battery Facility

Nippon Chikudenchi Co., Ltd., based in Chiyoda, Tokyo, has officially begun operations at their innovative energy storage facility, the NC Aoba District Kamiaiko B Battery Station, located in Sendai, Miyagi Prefecture. This facility will start its operations in the demand and supply adjustment market from June 30, 2026, marking a significant step forward in Japan's renewable energy landscape.

Overview of the Facility

The NC Aoba District Kamiaiko B Battery Station is designed to absorb and flatten the fluctuations in renewable energy generation, contributing to the stable supply of local electricity. This facility is positioned as a model case for demand-supply adjustment projects using grid-connected battery systems.

Key Specifications

• - Facility Name: NC Aoba District Kamiaiko B Battery Station
• - Location: Sendai City, Miyagi Prefecture
• - Rated Output/Capacity: 1,959 kW / 8,146 kWh (Battery system by TMEIC, Battery by CATL)
• - Start of Demand-Supply Adjustment Operations: June 30, 2026
• - Aggregator: Digital Grid Co., Ltd.

As Japan works to increase the use of renewable energy, managing fluctuations in power supply and demand has become a critical challenge for the national energy system. The role of battery systems in bridging the temporal gap between generation and consumption is increasingly recognized, forming a foundational infrastructure that supports grid stabilization and the sophistication of energy markets.

Collaborative Efforts

In this project, Nippon Chikudenchi and Digital Grid have cooperated in several roles:

• - Nippon Chikudenchi: Responsible for the overall development, operation, and site management of the project.
• - Digital Grid: Provides support for entry into demand-supply adjustment markets utilizing the Digital Grid platform and aggregation services.

This collaboration aims to establish a sustainable power adjustment model by integrating technology, operations, and market participation into a cohesive approach.

Future Developments

Nippon Chikudenchi plans to promote the establishment of more grid-connected battery stations nationwide. They aim to develop a regional energy model that integrates the wholesale market, demand-supply adjustment market, capacity markets, and disaster response energy support. Through their partnership with Digital Grid, they seek to contribute to the stable use of renewable energy and the achievement of a decarbonized society.
