The “whole of NEM” tab has been provided to provide an overview of how each client’s region of focus interacts with the other regions in the NEM. The following is a snapshot taken on the afternoon of Friday 29th May 2015, in the 14:15 dispatch interval:
This screen is comprised of 3 parts – each of which is described in turn below…
On the left-hand side of the display is a geographical view of the current (5‑minute) dispatch data across the NEM – with arrows showing direction of flow and (in this instance) “Heywood”, from VIC to SA, is shown as red because the interconnector is constrained.
In the middle section is a table showing (for each region) key (30-minute) trading prices:
- The actual trading price for the half-hour immediately preceding this point in time;
- The estimated trading price (which will be updated 12 times in this half hour) for the current half-hour (this is a key number you will want to keep a close eye on); and
- The estimated trading price for the next half-hour.
This is illustrated here:
On the right-hand side are 5 charts (one per region) showing the past 24 hours and then AEMO’s predispatch forecasts out till 4am the day after tomorrow. The chart shows:
- Regional demand;
- Regional available generation.
This is illustrated as follows:
The Display element within deSide has been developed in order to provide clients a clear view of what’s currently happening with respect to the electricity market, and likely to happen in the immediate future (and hence by which they can make decisions in terms of whether to curtail consumption, or switch on back-up generators, etc…).
