NAS Batteries – Designed for Stationary Energy Storage

NAS^® batteries are designed for stationary energy storage and boast an array of superior features:

High energy

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 6-8 hours

With its capability to discharge for 6-8 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.

Enhanced safety

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.
