Outlook · not a forecast · not financial advice
For each region we take the latest AEMO predispatch sensitivities run, look at every 30-minute interval in the next 4 hours, and report the share whose 95th-percentile RRP exceeds $300/MWh — the boundary between gridIQ's Amber and Red NEM tiers. National figure is an unweighted mean of regional probabilities.
