Aldoga Solar Farm on Sunday 12th October 2025 – Part 2
In this article we inspect power deviations from dispatched units that would have contributed to the frequency rise, and the deviations that would have contributed to the correction.
Frequency Performance Payments (FPP)
Belatedly highlighting the AEMO’s ‘Technical Review of the NEM Frequency Control Landscape’ from July 2025
Back in July 2025 we saw the AEMO had released this ‘Technical Review of the NEM Frequency Control Landscape’ … but are only noting this here now.
Frequency performance payments 44 days in, part 2
Categories with a longer bar left of zero are losing more of their spot energy market revenue to regulation and PFR costs.
Frequency Performance Payments 44 days in
An initial review of payment and cost outcomes of the first 44 days of financial operation of the FPP arrangements.
The commencement of Frequency Performance Payments (FPP)
Yesterday (Sunday 8th June 2025) saw the commencement of the new Frequency Performance Payments (a.k.a. FPP) method.
Examples of self-forecasting behaviours – under the hood of part 1
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.
Three themes from the Energy Storage Summit 2025
Dan provides a brief write-up of his notes from attending the Australian Energy Storage Summit in Sydney last week.
Two diagrams to help illustrate the changes coming with FPP (Frequency Performance Payments)
We've facilitated a number of articles on WattClarity relating to the looming FPP changes (now 10 weeks away). Here's two images I've drawn up to (hopefully) illustrate my understanding of what these changes represent.
Generator exposure to regulation costs under FPP
In his third article, Jack Fox uses the Non Financial Operation (NFO) data to take a look at some VRE units, and how they would have performed under FPP.
Today’s presentation to CEC’s Market & Grid Directorate
We thank the Clean Energy Council for the opportunity to share insights into revenue trends, cost trends, and analysis of upcoming changes for units operating in the NEM.
The top 10 batteries under FPP
In his second article, Jack Fox uses the Non Financial Operation (NFO) data to take a look specifically at batteries, and how they would have performed under FPP.
An initial look at Winners and Losers from Frequency Performance Payments (FPP)
In his first article, Jack Fox reports some initial observations from a review of the Non Financial Operations (NFO) data that's been published since Dec 2024.
Overview of Regulation FCAS costs in 2024
This article reviews regulation FCAS costs in 2024, relative to maximum capacity, and uncovers drivers behind high non-scheduled unit costs.
Comparing Frequency Measures (Frequency, FI, FM)
The faster-moving nature of the FM, with the introduction of FPP, removes predictability in the indicator for frequency performance.
Only 14 weeks to go until Frequency Performance Payments
Full financial operation commences 8 June 2025.
Incentivising primary frequency response
The implementation of the Primary frequency response incentive arrangements rule is driving change in how system frequency is controlled and paid-for. The changes stem from how the NEM will incentivise primary frequency response. 6...
Frequency Performance Payments project commences non-financial operation, 9th December 2024
AEMO's Frequency Performance Payments (FPP) project has commenced in production today under "non-financial operation" (NFO).
AER sends clear message on self-forecasting behaviours
Semi-scheduled generators shouldn't treat self-forecasts as commercial parameters. The regulator holds significant concerns with the biasing of self-forecasts for commercial benefit.
