In recent weeks we’ve fielded questions from a number of different parties about a mysterious jump in Queensland demand that some have observed late in 2014.
Pitts & Sherry in this Cedex report for January note that:
“Demand would have been even lower, were it not for the sharp increase seen in Queensland. The data suggest that this is entirely attributable to a very large new continuous industrial load of around 400 MW, which came on line on 27 October. The identity of this load appears, surprisingly, to be commercial in confidence. It is about the same size as either one of the two recently closed aluminium smelters. In a full year, a load of this size would add about 3.5 TWh to annual electricity demand, equal to almost 2 % of current NEM demand and over 7% of Queensland demand prior to its connection.”
Hugh Saddler (of Pitts & Sherry) also added a question for WattClarity readers in the comments on this post. For those without the same ability, the following trend from NEM-Review of daily demand extremes in Queensland shows the change described:
We’ve begun a process of digging further, to see what we can find – this we will fit in with other priorities, so an answer won’t be immediate.
If you (also) would like to hear of the results of our ongoing analysis, please email through to let us know. Depending on what we find (and how many are interested), we might share some of our findings on WattClarity – or we might just share them privately with interested parties.
Of course – if you already know what the answer is, and are happy to share with us, then let us all know by leaving a comment below!
