After Wednesday's first SIPS test, the Waratah Super Battery successfully completed its second this afternoon, as it inches closer to commercial operations.
A short post to note that the Waratah Super Battery tested its full SIPS capacity of 700MW for around two hours yesterday morning — the first time it was able to do this since last October's transformer failure.
A summary of key takeaways from an Australian perspective at the 2026 CIGRE Paris session — where the ongoing challenges of IBR interactions and the impact of data centres appear to be consistent themes across power systems globally.
Belgium-based guest author Gilles Chaspierre looks at two major occasions where the NEM was suspended. In 2016, when physics outran the market; and in 2022 when the market outran the physics. He reads the pair as one lesson about what spot prices cannot see.
In February David Leitch predicted batteries would eat coal volumes, not just price. Here he checks that call against the pipeline: 19 GW and 55 GWh coming, and up to 6 GW of coal displaced.
The strongest alignment for a free power window-start is when Qld, Vic and NSW all start at 11am, between April and October.
Fire has damaged Tungatinah Hydro Power Station in Tasmania, out indefinitely.
Four weeks ago we asked two questions 'where is the Energy/Capacity going to come from (in just 2 years) to replace all that Energy that Yallourn has been producing this winter?'. Here's the start of an answer to that question, though still incomplete...
Last Thursday 27th August 2026, the AEMC published a consultation paper with respect to ‘Dispatch limits for inverter-based resources’.
It’s quite a topical question (that we’ve contributed to recently), so I thought I would have a look at what is noted within the ESOO about the looming closure of Yallourn.

We look at five design differences between the Capacity Investment Scheme and the state auction schemes that came before and alongside it — and the improvements we've heard suggested by industry and the Nelson Review panel.
A year on from our 4-part series about the CIS, we take an updated look at the 89 projects awarded across the scheme's five NEM tenders — comparing what proponents have actually announced compared to the status AEMO assigns them for ESOO reliability modelling.
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.
Last week our team attended the CEC's Wind Industry Forum, then I presented at the EUAA's National Conference the next day. Moving between them in under 48 hours sharply reminded me how differently the NEM's supply and demand sides frame the challenges ahead.
The trend for declining skill as outlook increases is fairly linear. Encouragingly, outlooks at the 6-day mark still have better skill than random.
Uncertainty fluctuates considerably in the 6-day ahead forecasts. Some locations, appear to be generally more predictable than others, Queensland sites in particular.
