NAS batteries are the #1 choice worldwide for large-capacity energy storage.
NAS batteries are large-capacity batteries with many power grid applications. Superior function and performance possible only from decades of research, design, testing, demonstration, advanced manufacturing and over 15 years of proven commercial operation.

FEATURES OF NAS BATTERIES
NAS batteries are the most effective way to store large amounts of electrical energy discharging for six hours at rated output.
24/7 POWER SUPPLY
NAS batteries make 24/7 power supply feasible with solar power for 6-10 hours
and a NAS battery for 14-18 hours at one-third of the rated output.
When used with a fast Power Conversion System (PCS), NAS systems can respond to grid commands to store or deliver electrical energy in tens of milliseconds.
NAS batteries can be flexibly deployed in smaller spaces than other battery technologies.
With decades of experience, NAS batteries
have field-proven reliability exceeding 99%.
The safety of NAS batteries has been proven in testing by NGK and third-party authorities and from extensive field experience.
DEVELOPED FOR GRIDS
Development of NAS technology by NGK started in 1984 to provide a more flexible energy storage alternative than pumped energy storage, for the world's largest utility, TEPCO. The first NAS battery system deployment was in 1995.
NAS battery systems can be cascaded to any needed size (to 100s of MW or more).
Preventative maintenance is minimal and can be scheduled to avoid peak seasons. Maintenance can be done on particle systems while the rest of the system continues operation.
Operating Range Climates for NAS projects
range from the cold of Canadian winters to the heat of Abu Dhabi.
NAS batteries are rated at 4,500 full cycle discharges, or a 15-year calendar life, whichever occurs first. This lifetime is field-proven.
Containerized NAS batteries, in which NAS
battery modules are pre-installed, drastically reduce installation periods.
