Price trend
Monthly average dispatch price (RRP) by region. The structural separation between regions is the interconnector story; the spikes are the trading story.
Negative prices
Share of 5-minute intervals that settled below $0/MWh — the daytime oversupply signal driven by rooftop and utility solar.
FCAS prices
NEM-wide monthly average of the ten frequency-control markets. The 1-second raise/lower pair only begins once the very-fast market opened in late 2023.
Demand
Monthly average and monthly peak operational demand by region.
Peak / off-peak spread
Monthly average peak-window price (Mon–Fri 07:00–22:00; public holidays counted as weekdays) minus off-peak — the raw signal behind the peak-contract premium, and the spread storage and demand-response monetise.
Interconnector balance
Monthly average net interchange per region (AEMO convention: positive = exporting). Watch regions flip from importer to exporter as VRE builds.
Regional price correlation
12-month correlation of 30-minute prices. High cells = coupled regions; a weak cell is where interconnectors bind and spread trades live.
