Japanese Storage Battery Company Partners with Karatsu City for Disaster Preparedness

On August 6, 2023, Nippon Storage Battery Co., headquartered in Chiyoda, Tokyo, signed a cooperative agreement with Karatsu City in Saga Prefecture. This agreement aims to utilize energy storage systems during natural disasters to bolster local resource management and maintain essential services for residents.

Overview of the Agreement Ceremony

The agreement signing took place at Karatsu City Hall, attended by the mayor, Tatsuhiro Mine, and Hiraku Ushihara, the president of Nippon Storage Battery Co. The focus of this collaboration is to construct a reliable power supply system, enhancing disaster management and citizen services when emergencies arise.

Details of the Agreement

The partnership is structured to prepare for large-scale disasters and power outages by creating support systems that include provision of supplies, deployment of personnel, and electricity supply from the energy storage units. This proactive approach ensures readiness and effective response during emergencies.

What is a Grid-Connected Energy Storage System?

Grid-connected energy storage systems are large-scale battery installations that capitalize on renewable energy, also helping to manage the balance of electricity supply and demand. These systems charge when there is surplus energy in the network and discharge electricity as needed, proving critical for the stable operation of variable renewable energy sources like solar and wind power.

Emergency Applications of the Storage Systems

The energy storage facilities managed by Nippon Storage Battery feature external power outlets operated by qualified personnel. In emergency situations, these systems allow for the release of stored electricity to supply portable batteries, smartphones, laptops, and other critical communication devices. This enables effective information access and connectivity during crises.

Power Supply Capacity

Research indicates that a household of two requires approximately 17kWh of electricity over a 72-hour period (around 5.6kWh per day). Nippon Storage Battery's planned storage system, with a rated capacity of approximately 8MWh (8,146kWh), can supply power to around 470 households over the same period. Such storage solutions have the potential to become vital elements of regional infrastructure in disaster scenarios.
