Schneider Electric and NGK Partner to Promote Large-Capacity Energy Storage System

November 8, 2017 | News Brief | Schneider Electric and  NGK Insulators Ltd. have concluded a memorandum of understanding (MOU), to explore global opportunities to jointly market NGK’s NAS  battery and Schneider Electric’s inverter (Conext Core XC ES). In November, 2016, the team of NGK and Schneider Electric successfully conducted integration testing of the interface between the NAS battery and ES Box at NGK’s factory in Komaki City, Aichi Prefecture, central Japan.


With increasing demand and use of renewable energy, there is an increasing need for large-capacity battery storage systems, which can stabilize the distribution of electricity, and global demand is expected to grow going forward. The integration of Schneider’s energy management technology and NGK’s battery storage technology makes it possible to store large amounts of electricity with a smaller footprint. This offer is unique in the battery storage market and as a source of renewable energy, and it contributes to reduction in CO2 emissions.

The Conext Core XC ES is a series of central inverters designed for high efficiency and flexibility for battery-based energy storage systems. The series has peak efficiency of 99.1 percent and its flexibility allows the inverter to be configured with voltage and power output up to 680 kW.

NGK was the first in the world to commercialize the NAS battery system, which has the capacity to store megawatts of electricity. The NAS battery system boasts an array of superior features, including large capacity, high energy density, and long life. It is capable of maintaining high output of electric power for long periods of time.

Since 2002, NGK has delivered NAS battery systems with total output of more than 530,000 kW and storage capacity of 3.7 million kWh at about 200 locations worldwide. The systems are being used for load leveling and emergency power supply as well as stabilizing and smoothing power output from renewable energy sources. NGK continues to support the growth of renewable energy, cutting energy costs and reducing the burden on the environment by supplying large-capacity NAS battery systems.
