Executive read

What changed

Measurement. Minimum operational demand reached 504 MW against a 604 MW reference.

Decision implication. Lower registered demand increases the need to manage system strength, essential generation and the midday-to-evening transition on an isolated grid.

Evidence boundary. The event is a deterministic threshold or record comparison. It identifies a measurement that warrants investigation; it does not assign causality or quantify commercial exposure.
