Some brief analysis of the floods at Yallourn Power Station.
Demand was lacklustre but we’ve still given an impressive BBQ away to our competition winner for this summer….
Some summary points about how NEM-Wide demand across the NEM over summer 2011-12 was surprisingly low, with a very low peak achieved.
An article recently in one of the main papers about increased flows down the Snowy River prompted the question, internally, about how much the La Nina pattern of the past 24 months had impacted on production volumes from the hydro facilities around the NEM.
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 quick look at how NEM-wide demand has trended so far this summer (to define the starting point for our competition entrants).
This brief look raises questions about the demand seen in December 2011, so we compare against previous years.
Some snapshots of the market this afternoon, focused on the QLD region as demand continues to climb on a hot day this summer.
After adding in a few entries that we’d inadvertently missed (from a few people very keen for a BBQ) we have updated the sorted results table, and also the analysis.
What can we learn from the spread of entries received in our “Best Demand Forecaster in the NEM” competition, for summer 2011-12?
We’ve done some analysis here to help…
Analysis of what’s been happening in the NEM over summer 2011-12.
Including more than a decade of data for Queensland’s peak electricity demand (pre-NEM) reveals a more nuanced picture.
Extending our analysis of the pattern of demand growth (NEM-Wide) to see if the pattern has been the same at a regional level.
A list of 10 factors that are impacting on electricity consumption across the National Electricity Market.
Further analysis of the way that electricity demand patterns (NEM-wide) are changing in Australia’s National Electricity Market
A brief summary of NEM-wide demand this winter
