This is a larger set of articles tagged with ‘battery storage’.
Note that there is a smaller collation of articles categorised as dealing principally with Battery Storage.
This is the 2026 edition of our annual review into Q2 spot prices, where we find that average prices fell sharply in all NEM regions compared to Q2 2025, but more importantly, duration curves are changing shape.
This piece draws some parallels between the previous solar boom-bust cycle and the current battery buildout, and asks whether a 'battery correlation penalty' may already be taking shape.
Energy storage levels of NSW grid scale batteries are analysed for behaviour on 23 March 2026.
In this instalment of our annual review of the NEM’s expanding battery fleet, we draw on the GSD2025 to look at long-term trends in market revenue, high-price capture, the early returns of FPP, and network curtailment.
We find the trend for increasing enablement of the 'new' resources has only continued, that the new FCAS resources are the dominant providers of all FCAS services nowadays.
In this follow-on to his earlier analysis, David Leitch argues that as large-scale batteries enter the NSW market, it’s lost volumes rather than lower prices that could slash coal generators’ spot profits by 30 to 40%.
David Leitch reflects on how coal generators have adapted to a changing NEM, drawing on time-of-day profiles, and data from our GSD, and explains why — despite that flexibility — the underlying economics are becoming increasingly fragile as batteries reshape the evening peak.
In this guest-authored article by Endgame Economics, Oliver Nunn examines growing 'noise' in NEM spot prices — how increasingly frequent oscillations appear to have a structural, intraday pattern, what may be driving it, and why it matters for market behaviour and battery investment outcomes.
In an initial post-mortem of last night’s sustained period of high prices in SA, we take an initial look at how the region's utility-scale battery fleet responded, showing how aggregate stored energy was rapidly drawn down and how availability across the fleet tightened.
Linton and I had the pleasure of speaking to the CEC on Wednesday, this short article shares a couple of slides from the presentation and a list of questions we're still pondering about the CIS.
In the final part of our four-part CIS series, we zoom out to examine what government-backed Contract-for-Difference schemes are really achieving — drawing on policy lessons from the Nelson Review.
A short post to note our presentation for the CSIRO's South-East Asian System Planning Workshop in Brisbane this afternoon, and the analysis we shared.
Matt Grover from Fluence shares insights into the NEM's growing big battery fleet and what it means for the market and their operators. This article follows on from his keynote at the ESS two weeks ago.
Dan provides a brief write-up of his notes from attending the Australian Energy Storage Summit in Sydney last week.
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.
Declan Kelly thinks through and discusses competition issues that could arise from the increasing proliferation of auto-bidding software by big batteries in the NEM - and suggests some pre-emptive steps that that could be taken to mitigate potential issues.
Following on from a similar review this time last year, Dan provides an updated look at the economics and performances within the NEM's big battery fleet, making use of our recently released GSD2024.
Units typically cut over to their BDU counterpart in 2 weeks once the BDU was registered.
Philippe Orhan from Neoen shares this article which is adapted from his presentation about BESS bidding (and dealing with the complexity in the data) in the NEM at the recent All-Energy conference in Melbourne.
