Facing the possible power shortage due to the disaster of the Fukushima Nuclear Power Plant, all companies concerned are busily occupied with preparing for scheduled power outage. Shin-Kobe Electric Machinery developed a large-scale storage system including a led battery that can be introduced for about 700 million yen for a plant with power requirements up to 2,000 kW. Users can store power at night to prevent plant operation from being interrupted. They can set the time zone of scheduled power outage beforehand, and the storage system recharges and discharges automatically in accordance with the prearranged setups. It comes with the control device and the self-developed led battery that has a life of 17 years, more than six times longer life than that of the conventional model, and the ability to run the system for three hours. The control device allows for efficient usage of direct current and alternate current. The company developed this system for wind generation in 2008, and developed the software for control with haste. It takes three months to take delivery after placing an order, and another one week is needed for installation. The system is being built in its plant in Mie Prefecture that is not subject to scheduled power outage.
