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.

APPLICATIONS

RENEWABLES

Renewables / Power plants

GRID SOLUTIONS

Ancillary / Investment deferral

CONSUMERS

Industrial / Commercial & residential

MICROGRIDS

Islands / Remote grids and microgrids

FEATURES OF NAS BATTERIES

LONG DURATION

 

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.

FAST RESPONSE

 

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.

COMPACT

 

NAS batteries can be flexibly deployed in smaller spaces than other battery technologies.

HIGH RELIABILITY

 

With decades of experience, NAS batteries
have field-proven reliability exceeding 99%.

SAFETY

 

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.

SYSTEM EXPANSION

 

NAS battery systems can be cascaded to any needed size (to 100s of MW or more).

LOW MAINTENANCE

 

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.

WIDE AMBIENT

 

Operating Range Climates for NAS projects
range from the cold of Canadian winters to the heat of Abu Dhabi.

LONG LIFETIME

 

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

 

Containerized NAS batteries, in which NAS
battery modules are pre-installed,  drastically reduce installation periods.
