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.
Frequency performance payments (FPP)
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.
