Executive read
What changed
Measurement. Maximum five-minute price reached $15,140/MWh against a $5,000/MWh reference.
Decision implication. A short price spike can dominate daily storage and flexible-demand value even when the average price remains modest.
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.
