About NAS batteries
NAS batteries are a megawatt class large-capacity storage battery, implemented practically for the first time in the world by NGK. The batteries feature large capacity, high energy density (compact), and long life, and can provide a stable supply of electric power with a high output over long periods of time. They have been installed at over 250 locations worldwide, with a total output of over 720,000 kW (720 MW) and total capacity of approx. 5.0 million kWh (5,000 MWh) installed. NAS batteries were originally developed as the alternative technology to the pumped hydroelectric storage in urban areas. Nowadays they are used for various applications, including peak cutting through load balancing and emergency power supply, as well as stabilization of renewable energy and construction of smart grids, thereby contributing to reduced environmental load and realization of carbon neutrality. NAS batteries have obtained the certification based on stationary storage battery safety standard UL 1973 (cell and module level) and a test report based on UL 9540A standard*2, which is to verify batteries and storage battery systems fire risk, for confirming compliance with its evaluation criteria (cell, module, and installation level) through the evaluation program of UL Solutions, a global independent safety science company.
Product information on NAS batteries
*1Pumped storage hydroelectricity station: A facility that acts like a storage battery which uses water to store electricity. A regulating reservoir is created which stores water in the top and bottom areas of the power station. During times of high-power demand, water flows from the top to the bottom to generate electricity, and during times of low power demand, surplus power is used to reverse the rotation of the water wheel to pump water from the bottom to the top to be used for generating power again.
- *2NAS batteries container type (including the single batteries and modules on mounted) are covered.
