A large collection of articles pertaining to the ongoing ‘Energy Transition’ in any of a number of ways.
Specific sub-categories relate to such things as Coal Closure, and other aspects of the transition.
Transgrid's Project Assessment Conclusions Report for System Strength assessed more than 100 individual solutions aimed at helping to meet its system strength obligations under the National Electricity Rules.
As the technologies underpinning the power system change, so too must the approach to supporting system restart.
Alice Matthews examines how approval times for renewables vary widely by state and technology — with NSW wind projects facing the longest delays.
Under the new direction proposed, netting off would be applied to allocate IRSR. The proposal is open for feedback until 10 July 2025.
Transmission Company Victoria (TCV) yesterday announced a two-year delay to the project delivery timeline for the VNI West project.
The weather forecasts are alerting to the formation of an East Coast Low this week. The low is expected to sit just off the eastern cost of Australia, adjacent New South Wales.
After rejecting an earlier proposal, the AER has today approved the conversion of Basslink into a regulated transmission service.
WDR capacity has increased by 23 MW since our last look, and much of it happened recently.
In this guest post, Greg Williams calls for more research into how storage bidding—particularly auto-rebidding—is reshaping price formation and competition as flexible assets take centre stage in the NEM.
Rainfall and cloud cover has split Australia this autumn, delivering a mixed bag of solar irradiance conditions for solar farms across the NEM.
Paul Moore of Viotas look at recent supply-demand dynamics within the contingency FCAS markets and whether demand response can play a role.
A sequence of afternoon intervals stand out because the forecast appeared to be biased low – self-forecasts suddenly dropped roughly 30-40 percentage points and then increased a short time later.
Theoretically, if a self-forecasting system never offers forecasts for more than 60% of intervals it may perpetually skip the performance assessment and the system could continue for use unsuppressed.
This guest-authored post by Cameron Shield from Lockton follows on from his presentation at the CEC's Investor Forum earlier this year, where he urged the audience to "sell risk, don't buy insurance".
Taking a guess at frequency need to earn a positive causer-pays factor through self-forecast biasing appears at-best uncertain in the intervals we review.
In another style of biasing a self-forecast, "lunar megawatts" represent an expectation of solar farm generation at night when it really should be zero.
The forecast differences would contribute to improved lower RMSE and MAE scores, relative to AWEFS_ASEFS, in the weekly performance assessment.
In today’s article (part 1 in this series) we present an example of biasing (at an unnamed solar farm), which we find aligns with FCAS cost mitigation.
Ben Nethersole from Baringa summarises the different contracting routes available for renewables and storage, and how project business cases are increasingly stacking these together.
Let’s now return to Monday 26th May 2025 to look at aggregate ‘Dispatch Error’ across both Semi-Scheduled fuel types for all dispatch intervals in the day.
