Initial look at the latency of all rebids
Following from some analytical work performed in testing for Five Minute Settlement, here's a view of latency of rebids (all DUIDs, all commodities) in recent months that prompts...
Detailed Analysis
Is the predictability of day-ahead demand improving?
Day-ahead demand forecasts will be integral to any future 'Ahead Market'. We take a look at the current state and accuracy trend of demand forecasts made 24 hours...
Potential Tripwire #3 When is a load not a load?
A feature of the upcoming EMMS technical specification that distinguishes demand response units from scheduled loads could impact some users of NEM data, if left unmanaged.
P30 Predispatch forecasts after 5-minute settlement–what do they mean?
30-minute pre-dispatch provides critical forward price information to the NEM - but what exactly will it mean after five-minute settlement? Marcelle takes a look.
Ranking wind farm performance and FCAS costs in the NEM in 2020
Which wind farms performed best in 2020? Marcelle extracts data from the GSD2020 to compare spot (and LGC) revenue, and FCAS cost performance, across wind farms in the...
Where’d the wind go, during the last week of April?
Over the week that has just passed we kept noticing production from wind farms across the NEM was fairly muted - so we've had a look at what...

Large-scale solar farm revenue in 2020 part 2 – considering LGCs
Marcelle extends last week's comparison of solar farm energy spot market revenue in 2020 by adding in an estimate of the LGC (green certificate) revenue.
A Comparison of Large-Scale Solar Farm Revenue in 2020
Which solar farms performed best in 2020? Marcelle compares spot revenue performance across the NEM.
Using the GSD2020 to explore operating patterns across generation types
With the release of the Generator Statistical Digest 2020, Marcelle Gannon takes a look at how it can be useful for identifying and exploring different patterns of generation.
AEMO releases ‘Quarterly Energy Dynamics’ for Q4 2020
Quite a synergistic coincidence today that, at the same time as we are finalizing the release of the GSD2020, we see the AEMO publishes its Quarterly Energy Dynamics...
