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. Hover (mouse over) the bars to see the units.

NB: The sources of generation including wind and solar for each State can be viewed on the fuel mix tab.

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 circles and arrows on the chart is usually grey. When the flow of energy on an interconnector reaches either its current import or export limit the circles and arrows will turn orange

Data source

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).

Overview

Select the options you wish to view at the top of the chart. You can switch between States, chart or table view, and 30-minute or 5-minute data.

The chart shows either 30-minute or 5-minute data including current and historical Spot Price (Spot Price 5/30min), Forecast Spot price (Forecast price Pre-dispatch), current and historical Scheduled Demand (Scheduled Demand 5/30 min) and Forecast Scheduled Demand (Scheduled Demand Pre-dispatch).

The spot prices displayed are time-weighted spot prices.

Data source

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).

Select the options you wish to view below - you can switch between individual States or the National Electricity Market (NEM) as a whole, and between current, 24 hour, 48 hour, 3 monthly or annual data.

How to read:

  • The fuel mix visualisation shows the breakdown of energy sources in the NEM over different periods
  • There are five options for periods: instantaneous data shown in the Current view and data aggregated over time in 24/48 hrs, 3/12 months
  • Current view:
    • The Current view shows the source of energy for the current 5 min dispatch interval and selected region. This figure is instantaneous and measured in MWs. The generation is aggregated by fuel source and shown as both absolute and proportional to the regional total
  • Other times periods:
    • For the 24 and 48 hr, 3 and 12 months views, energy is aggregated over the full-period in the Mix Summary chart and hourly (24 and 48 hr), daily (3 months) or weekly (12 months) in the Mix by Time chart.
    • Moving your cursor over the stacked area Mix by Time chart shows aggregated energy generation for the period hovered over. The time period is shown in the black text box e.g. 13:00 – 14:00 21 Oct. Energy is aggregated over that period for the fuel sources below the area chart

Frequently asked questions:

Q: What types of generation are included in the fuel mix? Is non-scheduled generation included?
A: Generation data includes scheduled and semi-scheduled units.

Q: Does this include rooftop solar PV generation?
A: Rooftop solar PV is not currently included in the fuel mix visualisation.

Q: Where can I source data for longer than 12 months ago? Where can I find more detailed data?
A: For detailed, disaggregated and comprehensive data needs, please visit NEMWEB.

Q: Why is the current view data show in MWs and the time periods in MWhs?
A: The Current view is showing the instantaneous generation for the current 5-minute dispatch interval. Data for the 24 hr, 48 hr, 3 month and 12-month options is aggregated, please see the 'How to read' section above.

Overview

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.
