deSideThe Regional Tabs
For each region in the NEM, deSide has one tab that contains tables and charts with price, demand, and inter-regional flow data. Each regional display is made up of the following elements:
- Region Trading Price Graph
- Region Trading Price Table
- Whole of NEM Schematic
- Regional Dispatch Graph
- Regional Dispatch Price Table
- Regional Predispatch Price Sensitivities
Region Trading Price Graph
The Region Trading Price Graph displays the 30 minute trading price together with forecast price sensitivities, regional demand, available generation, and any price thresholds you have configured (show me how to configure price thresholds).
The graph shows previous values for trading intervals that have elapsed, as well as forecast predispatch values.
deSide Silver Model Only Data
Pre-dispatch price sensitivities are available only in deSide Silver
Region Trading Price Table
The Region Trading Price Table Table contains the trading price for the immediate previous trading period, the forecast for the trading period that is in progress, and forecasts for subsequent trading periods. This table also shows the current cumulative price for the region.
Whole of NEM Schematic
The Whole of NEM Schematic shows price and demand information about each of the regions in the NEM, as well as details of the power flows between them.
Regional Dispatch Price Graph
The Region Dispatch Price Graph displays 5 minute trading price data, together with regional demand, available generation, and any price thresholds you have configured (show me how to configure price thresholds).
The graph shows previous values for dispatch intervals that have elapsed, as well as forecast predispatch values.
Regional Dispatch Price Table
The Region Dispatch Price Table displays 5 minute trading price data forecasts.
Regional Predispatch Price Sensitivities
The Predispatch Sensitivities table shows the predispatch sensitivity data for the current region. Predispatch sensitivities are values that AEMO publish to allow for a more accurate view into the many possible future prices for a region. Each value is an estimate of what the next trading price would be if the demand for a related region changed.
To go into this in a little more detail, in the image to the below, you can see that the second entry from the top states:
What this means, is that if the demand in Queensland was 500 MW less than expected, then that is the price that AEMO has estimated. This extends to other regions as well, as you can see in the image below, as the last entry reads:
This is AEMO's estimate for what would happen to the next QLD trading price if the demand in NSW was suddenly 500 MW less than expected.
deSide Silver Model Only Data
Pre-dispatch price sensitivities are available only in deSide Silver
