## Scope and engineering interpretation

Storage projects use MW for power and MWh for energy capacity. Batteries, power conversion, control systems and the substation create different technical interfaces. This interpretation preserves the disclosed ratings while distinguishing balance-of-plant responsibility from the supply of the complete battery technology.

## How to read the announcement

The project facts above come from the linked company announcement. The technical discussion is an editorial interpretation of their practical significance. The stated contract, construction or operating milestone retains its original context; no additional date, customer or completion outcome is assumed.
