| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | A separate live trial demonstrated a grid-forming BESS acting as an island anchor at 8 MW, including energization of a 132 kV line and associated transformers; that trial should be cited if the intended claim is demonstrated black-start capability. |
