Structure of NAS Energy Storage System

The Easiest Way to Achieve Multiple Megawatt-Hour Energy Storage System

The NAS battery system is designed to be easily able to expand the capacity as much as needed in one site or several separate sites. The scalability of NAS installation to many 10s or 100s of MW for durations of 6 to 7 hours is at a scale that can defer or eliminate some transmission, distribution and generation investments especially when used in association with variable renewables for a clean solution. (The current largest system at one site is 50MW, 300MWh.) The construction leadtime is significantly shorter than upgrading or building transmission/distribution lines or substations.

A NAS battery system consists of battery enclosures, battery modules and a PCS (AC/DC power conversion system) as the main components. The NGK scope is the battery enclosures and battery modules. NGK works with several PCS manufacturers to complete the battery system.
It is also suitable to install in severe weather conditions, because the battery enclosure and insulated battery modules can resist a wide range of environmental conditions and climate.

NAS Battery System

Container type unit

The NAS battery system is a "Plug and Play" design built around standard 20 foot ocean freight containers. The containerized design expedites transportation and installation and helps minimize installation costs.

Rated Output 800 kW and 4,800 kWh
Configuration Four container subunits,series connected.
A subunit includes six NAS modules, each rated at 33 kW and 200 kWh.
Dimension 6.1W x 5.6D x 5.5H (m)
Weight 86 tonnes

Package type unit

The enclosure package and battery modules are installed on site. This design achieves more compact system comparing with containerized design.

Rated Output 1,200kW and 8,640kWh
Configuration 40 NAS modules, each rated at 30kW and 216kWh.
Dimension 10.2W x 4.4D x 4.8H (m)
Weight 132tonnes
