Given our ongoing interest to many things related to electricity demand (including how cool weather impacted “summer” peak demand in Tasmania) it did not pass our notice that Tasmanian demand, over the last few mornings, has crept up towards the red zone – as seen here in this snapshot from NEM-Watch earlier:
In contrast to the other regions on the map (all in the green zone) we can see the Tasmanian demand relatively high (up to 1666MW), in historical terms.
Powering up NEM-Review, all we have time to do this morning is generate this trend of daily demand patterns over 10 years of NEM history for the Tasmanian region:
This chart uses Trading (half-hourly data). In the chart we can see that the scheduled demand in Tasmania has not exceeded 1650MW since 2 half-hours in winter 2011. Looking at what happened this morning on the same basis (i.e. using half-hourly data) we see Tasmanian demand for the 08:30 trading period was 1650MW.
Hence, early this winter we have seen Tasmanian demand peak at levels not seen for 4 years.
