Some recent changes in the MT PASA forward view of available generation capacities in NSW seem to imply that the declining demand might have taken another victim.
A cold evening in the NEM, and yet demand can’t make it past 30,000MW – which would have been quite startling 4 or 5 years ago (but not now, as demand has been declining for a number of reasons).
Why are we investing significant time in completing this review of what was remarkable price volatility in QLD over summer? We’re primarily a software company that develops shrink-wrapped products used by about 100 market participants, spectators and commentators.
Prompted by a reader’s question, we provide some further analysis into which brown coal plants have been declining output in recent times, and why this might be the case.
A chart and a table presented today at FutureGAS highlighting how the dominance of coal in power generation across the NEM is starting to shift.
Some analysis of the extent to which Demand Diversity (the degree to which peak demands in each region occur at different times) has changed in 15 years. If there are changes, it could be a factor at play in why peak demand has been changing.
A longer-term look at how summer (peak and average) demand has trended over the 15 years of NEM history to date.
A number of recently announced closures of (and cut-backs in) a variety of coal-fired power station units across the NEM (including Northern, Yallourn, Munmorah and Tarong) – claimed to be a result of carbon pricing – generated significant interest in the press, and interested us to open NEM-Review and have a look at longer term trends, and the extent to which that attribution might be true.
A look at the trend towards deeper liquidity of trading of electricity derivatives in Australia’s National Electricity Market (NEM).
The range of questions we’ve been asked over the course of the past 2 weeks (since the introduction of the Carbon Tax) seem to resolve to these 3 key questions.
A quick look at the demand levels on Saturday 25th driven by hot weather in VIC and SA. What would have happened had this been on a weekday?
Looking further (after making the first post today) I see that the demand did rise above 30,000MW across the Australian National Electricity Market today – still a very low level for the highest demand so far this summer…
High temperatures in Victoria and South Australia – but demand is still well down on the all-time records for those regions.
NEM-wide demand is still to crack the 30,000MW barrier (which used to be fairly commonplace several summers ago). This is not providing good news for generators.
By now our schools are full again, and businesses are back at work – so it is timely to review how electricity demand in the NEM trended through the holiday months of December and January.
A list of 10 factors that are impacting on electricity consumption across the National Electricity Market.

A brief summary of NEM-wide demand this winter
Some observations about where average demand in the NEM has trended over the 12 years of NEM history, following the work done in compiling the 2011 Issue of the “Power Trading Schematic” Market Map.
Some analysis prompted by a short article in the AFR talking about a reduction in emissions over summer 2009-10 (with the possible implication being that emissions have turned the corner).
