A collation of articles categorised as dealing principally with Battery Storage.
Note that there are a larger set of articles tagged with ‘battery storage’.
Paul Austin explains how utility-scale batteries can use time block derivatives — selling Evening Peak and buying Midday contracts — to lock in intraday spreads and reduce exposure to spot prices, giving a useful baseline for budgeting, investment cases and revenue support scheme bids.
Guest author Franz David Schaefer digs into the potential "battery correlation penalty" flagged on this site, running a three-year, per-unit analysis of every NEM battery against a perfect-foresight benchmark — finding batteries may be bidding up their own midday charging costs.
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.
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.
The NEM’s first true solar-battery hybrid in the NEM — the 98 MW Quorn Park Solar Hybrid with a 20 MW BESS — has begun testing as the inaugural “mixed” Aggregate Dispatch Group under AEMO’s new rules.
Almost exactly 3 months ago we posted a ~12 month chronological record of the history of Waratah BESS. Due to observations today (and questions and conversations leading from them) it was worthwhile to update this trend.
It was the RenewEconomy article some weeks ago that initially drew our attention to this White Paper ‘The Role of Grid-Forming Inverters in Providing Inertia (in the NEM)’ from Tesla Energy - but we thought it's worth linking to it directly here now.
The Waratah Super Battery System Integrity Protection Scheme (SIPS) was enabled by TransGrid at last Friday 1st August 2025. This prompts this look back on operations thus far.
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.
Paul Moore of Viotas look at recent supply-demand dynamics within the contingency FCAS markets and whether demand response can play a role.
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.
James Tetlow of Overwatch Energy shares this article which is adapted from his presentation about BESS operations in the NEM at the recent All-Energy conference in Melbourne.
Pan Galanis from Akaysha Energy presented the content from this article at the 'Operating in the NEM' session at All Energy in Melbourne last week.
Alex Leemon of Gridcog delivered this presentation about Big Battery Revenues in the NEM at All-Energy in Melbourne last week.
Specifically with respect to All Energy 2024, I can categorically state that the ‘Operating in the NEM’ session that was conducted on Thursday 24th October 2024 was easily the best* session I attended throughout the event.
