On Friday 20th December 2024 we saw the release of the Final Report from the Select Committee on Energy Planning and Regulation in Australia, which has been run by the Australian Senate in recent months
Read MoreGuest author Allan O’Neil examines some recent episodes of price volatility (particularly 30th July to 5th August 2024) and whether they were driven by a shortage of supply, or other factors.
Following on from earlier articles about price volatility on Tue 30th July 2024 (particularly in South Australia), guest author Allan O’Neil takes a closer look at the operation of battery units in South Australia.
We just witnessed another eventful Q2, with at least four drivers contributing to significant price volatility. This is our annual review of Q2 prices, where we compare these outcomes against the long-term trend.
Enroute to Melbourne today for the EUAA National Conference starting tomorrow, I grabbed some flight time to have a quick read through the Grattan Institute’s latest offering – a 45-page report appropriately titled ‘Keeping the Lights on’: Quite topical that…
Last Tuesday 23rd April 2024 I spoke with an audience organised by BofA Securities with respect to ‘Risk, Uncertainty and Volatility in the energy transition’. Here’s one illustration of why the spread of spot prices in the NEM has been increasing in recent years.
In Part 2 of their modelling and analysis project, David Leitch and Paul Bandarian discuss the modelled results of their sharpe ratio-maximised VRE system, including additional considerations regarding transmission.
With GenInsights Quarterly Update for 2023 Q4 completed, and some time till the end of 2024 Q1, we’ve looked back at Tuesday 14th November 2023 (when AEMO had concerns about low System Strength in NSW) and looked at the level of inertia actually seen in the grid. A useful Case Study to say ‘what would have happened without Eraring?’
David Leitch and Paul Bandarian present and discuss the model they’ve created which uses a maximum Sharpe ratio wind and solar portfolio for the 2025 calendar year, drawing upon data from the AEMO’s 2024 ISP.
In light of another transmission tower collapse caused by convective wind gusts, we’ve invited wind loading expert Dr John Holmes to explain this phenomena.
It’s Thursday 15th February 2024 and (in amongst the detailed analysis relating to Tue 13th Feb 2024 in Victoria) we’re releasing the GSD2023 … the Generator Statistical Digest for the 2023 calendar year.
Nick Bartels from Greenview Strategic Consulting uses the GSD2023 to examine minimum and maximum generation levels at various coal and gas plants in the market.
David Leitch provides his top insights from reading his (pre-published) copy of our GSD2023 – due to be released later this week.
Noting an earlier article on PV Magazine about a direction from Energy Safe Victoria relating to the Cohuna Solar Farm, we take a quick initial look at operations in the AEMO market data.

This morning I was fortunate to listen into an ESIG Webinar with respect to their report ‘Weather Dataset Needs for Planning and Analyzing Modern Power Systems’
Following the release of GenInsights Quarterly Updates for 2023 Q3 we’ve chosen to share here one of the clear challenges for large-scale VRE that is emerging (particularly in 2023 Q3) due to the rise and rise of rooftop PV.
Guest author, Allan O’Neil, takes a detailed look at how VIC1-NSW1 transfer capability has been limited frequently due to constraints related to the 051 line in southern NSW, and what it means in terms of inter-regional settlements residue accumulations, market efficiency overall, and the energy transition.
Yesterday (Wed 18th Oct 2023) Origin Energy held its Annual General Meeting, with discussion wide-ranging. Here’s two things that jumped out to me about the Eraring Power Station, which is currently slated to close in 2025.
A quick article on WattClarity pointing to some research completed by Shukla Poddar and others about what future solar profile might be across Australia, in a climate changed world.
