Introduction

The Terumaru Battery Project has officially launched by Tokyu Power Supply, which aims to distribute 1,000 home storage batteries free of charge to households in Tokyo that do not have solar panels installed. This large-scale initiative is designed to boost urban resilience and provide a solution for disaster management while helping participants save on their electricity bills.

Project Overview

Starting from August 28, 2025, interested households can apply on a first-come, first-served basis for the provision of these free storage batteries. The project not only includes the installation of the battery systems but also covers maintenance and operational support for about ten years where they will be remotely controlled by professional staff. The batteries will be charged during off-peak hours when electricity rates are low and will discharge during peak times to maximize cost savings for the participating families.

Disaster Preparedness

In the event of a power outage caused by disasters or accidents, the battery systems can automatically switch to autonomous operation, ensuring a continuous supply of electricity. This feature significantly enhances the preparedness for any unforeseen circumstances and provides peace of mind for the residents.

Cost-Free Installation

The project promises an entirely cost-free experience for the households involved. Participants will not incur any expenses for the installation, maintenance, or monitoring of the storage batteries. At the end of the loan period, the batteries will be transferred to the households at no charge. This approach aims to increase the adoption of home storage batteries, promoting their widespread use across residential areas.

Demand Response Participation

Additionally, since Tokyu Power Supply owns the storage batteries, they will be able to effectively manage and control the 1,000 units collectively. This capability will allow participation in Tokyo's Demand Response (DR) demonstration project, aiming to stabilize the power supply system during times of high demand.

Commitment to Renewable Energy

Tokyu Power Supply is committed to its corporate philosophy of providing a new lifestyle experience through energy. The company aims to transition not only electricity used in homes and offices to renewable energy but also to transition all forms of transportation, including railways and buses, to be powered by green energy. This initiative is part of a broader strategy to create sustainable living environments in urban settings, working closely with various stakeholders to address social issues and create new value.

How to Apply

Interested households must meet certain conditions to qualify for the battery project. Applications can only be submitted through the dedicated project website. The project is intended for residents under the age of 70 living in Tokyo who own single-family homes built after June 1, 1981, and do not currently have any solar power generation equipment.

To summarize, the Terumaru Battery Project by Tokyu Power Supply presents a significant opportunity for Tokyo residents to participate in a beneficial initiative that not only supports personal households but also contributes to the overall stability and resilience of the urban power system. The collaboration with local authorities underscores a commitment to harnessing renewable energy sources effectively while providing practical solutions for everyday living. We encourage all eligible households to consider joining this innovative program and benefit from its advantages.
