Japan Storage Battery Company's Disaster Support Agreement with Iwata City

On April 14, 2024, Japan Storage Battery Company (JSC), headquartered in Chiyoda, Tokyo, established a disaster support agreement with Iwata City in Shizuoka Prefecture. During the signing ceremony that took place at the Iwata City Hall, notable attendees included Iwata Mayor Hiroaki Kusachi and JSC's President, Shuichi Urushihara. This initiative aims to utilize the company’s grid-connected storage battery facilities within Iwata City to bolster local disaster response capabilities and ensure the continued delivery of city services during emergencies.

Overview of the Disaster Support Agreement

The established agreement is designed to set up a reliable electrical supply support system in collaboration with Iwata City during disaster occurrences. By working in conjunction with local authorities, JSC seeks to enhance the region’s disaster preparedness and improve citizen services.

What are Regional Disaster Support Agreements?

Regional disaster support agreements are collaborative frameworks between municipalities, private enterprises, and organizations to prepare for large-scale disasters and unexpected power outages. These partnerships aim to establish a support network for supplying essential goods, deploying personnel, and ensuring a steady electricity supply to be effective during critical times.

Understanding Grid-Connected Storage Batteries

Grid-connected storage batteries are large-scale energy storage systems installed to optimize the use of renewable energy and maintain the balance of electricity supply and demand. These systems connect to the power grid, charging during surplus energy times and discharging as needed, particularly benefiting variable-output renewable energy sources such as solar or wind power.

Utilization During Emergencies

JSC’s grid-connected storage facilities are equipped with external outlets, allowing licensed technicians to manage and operate the energy supply during emergencies. In such cases, accumulated electrical power can be utilized to charge portable batteries or provide electricity for critical devices such as smartphones and laptops, which aid in communication and information acquisition during crises.

Energy Supply Capabilities

Research suggests that a two-person household requires approximately 17 kWh over 72 hours during emergencies (around 5.6 kWh per day). JSC’s planned storage facility, with a rated capacity of about 8 MWh (8,146 kWh), is capable of supplying energy for approximately 470 households over the same period. Such battery storage facilities are anticipated to play a crucial role as part of the regional infrastructure in times of disaster.

About Japan Storage Battery Company

Japan Storage Battery Company focuses on promoting grid-connected storage batteries as a means to enhance the energy and power sector's flexibility. The company operates centered on three core business areas:
1. Construction of Storage Facilities: JSC identifies suitable land and coordinates all aspects with power companies and construction contractors for establishing storage battery installations, ensuring reliability and optimal solutions.
2. Operation and Maintenance: The company conducts statutory inspections and monitoring to ensure stable operations of the storage facilities for 20 years or more, emphasizing long-term safety and functionality.
3. Market Creation: JSC aims to create a sustainable market around grid-connected storage batteries, enabling easier entry for businesses and investors, and promoting a stable energy supply for Japan.

Future Endeavors

Currently, over 70% of Japan’s electricity relies on fossil fuels, primarily through thermal power generation. Transitioning to renewable energy is essential for building a sustainable society and reducing CO2 emissions. JSC is committed to solving these issues by promoting the deployment of grid-connected storage systems, contributing to the enhancement of flexibility in energy supply. Moreover, the company aims to establish mechanisms that allow more individuals to participate in renewable energy financing, supporting sustainable growth initiatives. JSC plans to initiate operations at 80 storage facilities by 2026.
