Murata Manufacturing Co., Ltd. has developed a container-type large-scale energy storage system for instantaneous voltage drop countermeasures, and has released the developed system to the market in cooperation with Japan Facility Solutions, Inc. (JFS, President Mr. Yusuke Shibata), a 100％ subsidiary of TEPCO Energy Partner, Inc. (TEPCO EP, President and Representative Director Mr. Toshihiro Kawasaki).
The energy storage block of this system uses the olivine-type iron phosphate lithium-ion battery “fORTELION” manufactured by Murata subsidiary Tohoku Murata Manufacturing Co., Ltd., and is used in combination with an AC-DC converter made by Meidensha Corporation (President Mr. Yuji Hamasaki) or YAMABISHI Corporation (CEO Mr. Kazunori Hasuike).
This product will be introduced at the INT’L SMART GRID EXPO held at Tokyo Big Site from Wednesday, February 28 through Friday, March 2.
Instantaneous voltage drop (a momentary drop in power system voltage) such as due to lightning strikes to power transmission lines may have a large impact, such as the stoppage of production lines in factories, etc. Furthermore, in an advanced information society, data centers and factories that manufacture high value-added products, such as precision instruments, require a more stable power supply than ever before.
Murata’s newly developed container-type large-scale energy storage system uses olivine-type iron phosphate as the cathode material, which has a high safety standard without concerns of fire and realizes a useful lifespan of up to fifteen years. In addition, the developed system provides a higher amount of power than that of general lithium-ion batteries, which leads to installation space savings. Moreover, this product also has a demand response function that can help to level power supply by making use of energy storage to achieve efficient energy use.
Going forward, Murata will continue to develop high input (2C charging) high output (6C discharge) large-scale energy storage systems, and provide various solutions that realize not just instantaneous voltage drop compensation measures and demand response, but also mitigation of short-term fluctuations and adjustment of frequencies.

Explanation of terms
Demand response: To change the power consumption pattern in accordance with the electricity rate price setting or payment of incentives so that the demand side suppresses power usage when the wholesale market price soars or system reliability drops.
