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.
Categories with a longer bar left of zero are losing more of their spot energy market revenue to regulation and PFR costs.
An initial review of payment and cost outcomes of the first 44 days of financial operation of the FPP arrangements.
Yesterday (Sunday 8th June 2025) saw the commencement of the new Frequency Performance Payments (a.k.a. FPP) method.
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.
Dan provides a brief write-up of his notes from attending the Australian Energy Storage Summit in Sydney last week.
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.
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.
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.
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.
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.
This article reviews regulation FCAS costs in 2024, relative to maximum capacity, and uncovers drivers behind high non-scheduled unit costs.
The faster-moving nature of the FM, with the introduction of FPP, removes predictability in the indicator for frequency performance.
Full financial operation commences 8 June 2025.
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...
AEMO's Frequency Performance Payments (FPP) project has commenced in production today under "non-financial operation" (NFO).
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.
