We took particular note in the reference made to OneSteel’s curtailment of load at the times of peak price, and that they have utilised this approach as a means for securing (significantly) lower average cost of electricity over a year.
As you may be aware, we supply our deSide (www.deSide.info) software as a means for informing OneSteel of the timing of these curtailment opportunities.

On the 4th of February at around 11am energy users in NSW appear to have curtailed their load in response to high prices, resulting in a significant drop in demand. Simultaneously, network conditions and generator rebidding caused the NSW pool price to jump back and forth between extreme prices close to VOLL ($10,000/MWh) and the Market Floor Price (-$1,000/MWh).
Weather forecasts tell of an expected hot weekend on Saturday (in Melbourne & Adelaide) and then Sunday (in Sydney) – which has led to some news articles talking about “searing heat across the southeast putting energy supplies under pressure”. Let’s not get carried away – it looks like the levels of demand will be pretty moderate.
