GridStore
Commercial & Industrial Energy Storage · New Zealand

Storage sized to your site.

GridStore is ASKA's commercial battery platform — deployed from a few hundred kilowatt-hours behind a small commercial meter to multi-megawatt systems and containerised systems. One engineering standard, one service model, one operating intelligence, at every scale.

Sizing

From a single cabinet to site-scale systems.

Most NZ commercial sites sit behind a 500 kVA to 1 MVA transformer. GridStore systems are sized to the transformer, the load shape, and the value streams on your tariff — drag to explore the range, or jump to a common size.

Arranged as 8 cabinets
One megawatt of rated power. Fits behind a full 1 MVA transformer — a common upper ceiling for a single site.

The platform does not stop at twelve cabinets. For large industrial and grid-adjacent sites, ASKA delivers containerised GridStore systems in the 4 to 6 MW class — same operating intelligence, same engineering discipline, larger form factor. Where a project sits at that scale, we design it with you directly.
