Price and Demand
The chart shows real-time data (5-minute) for each region including current Dispatch price, Scheduled Demand, Scheduled Generation, Semi-scheduled generation and flows (and limits) across each interconnector connected to the region.
For interconnector values, negative and positive signs indicate the direction of flow. Positive values indicate flows north or west e.g. TAS to VIC, VIC to NSW, NSW to QLD, VIC to SA. Negative values indicate flows in the reverse direction.
Import and export limits are the limits up to which power can flow on the interconnectors in either direction. Export limits refer to the maximum permissible flow north or west and import limits refer to the maximum permissible flow south or east.
The colour of the interconnector boxes on the chart is usually grey. When the flow of energy on an interconnector reaches either its current import or export limit the box will turn red.
Source of data (MMS tables and fields): DispatchPrice.RRP (Dispatch price), DispatchRegionSum.ClearedSupply (Scheduled Demand), Semi-scheduled generation (DispatchRegionSum.Semischedule_ClearedMW), DispatchRegionSum.DispatchableGeneration - DispatchRegionSum.Semischedule_ClearedMW (Scheduled Generation), Interconnector Flows and limits (DispatchInterconnectorres.MWFlow, DispatchInterconnectorres.ExportLimit, DispatchInterconnectorres.ImportLimit).
The chart shows 30-minute data including current and historical Spot Price (Spot Price 30min), Forecast Spot price (Forecast price Pre-dispatch), current and historical Scheduled Demand (Scheduled Demand 30 min) and Forecast Scheduled Demand (Scheduled Demand Pre-dispatch).
The spot prices displayed are time-weighted spot prices.
Source of data (MMS tables and fields): TradingPrice.RRP (Spot price 30 min), PreDispatchPrice.RRP (Forecast Spot price), TradingRegionSum.ClearedSupply (Scheduled Demand 30min), PredispatchRegionSum.ClearedSupply (Scheduled Demand Pre-dispatch).
The Average Price table shows average prices for each day in the current month. RRP refers to the average spot price ($/MWh) per region for each day, and PEAK RRP refers to the average peak price from 7:00am to 10:00pm EST (weekdays excluding NEM Holidays). Please note that under the historical data the annual year refers to the financial year, not calendar year.
