NAS® Batteries - Designed for Stationary Energy Storage
NAS® batteries are designed for stationary energy storage and boast an array of superior features:
A single NAS® battery container features 1.45MWh energy. By combining containers, the total energy of the system can be easily scaled up to multiple MWhs.
Discharge duration 4-8 hours
With its capability to discharge for 4-8 hours, NAS® batteries are ideally suitable for long duration applications such as time shift or peak shaving, but also for grid upgrade deferral.
Long life time 20 years / 7,300 cycles
Thanks to its slow degradation, an NAS® battery maintains its functionality for up to 20 years or 7,300 equivalent operation cycles (whatever comes first).*
* The equivalent operation cycle is only defined by accumulated discharged energy and independent from operating Depth-of-Discharge (DoD). Subject to compliance with the maintenance cycles and further technical requirements.
As safety is of paramount importance, NAS® batteries manufactured by NGK Insulators, Ltd. meet the highest safety standards. On behalf of BASF, TÜV Rheinland conducted a safety audit. Please find the summary here.
All materials used in NAS® batteries manufactured by NGK Insulators, Ltd. are abundant on earth.
When used in combination with a fast Power Conversion System (PCS), NAS® batteries can respond within milliseconds.
The battery requires only minimal preventive maintenance.
"All climate" technology
NAS® batteries can be deployed in all climate zones.
With more than 15 years of experience, NAS® batteries have demonstrated unprecedented field-proven reliability.
