Ninth time is the charm: Callide C4’s return was another example of an overly optimistic timeline in the NEM
A chart showing the countdown to expected RTS for Callide C4, compared to the actual outage timeline.
Callide C4 offline again, as planned–but outage extended. Have they found something?
A short update (on Friday 6th September 2024) about Callide C4, which has come off for a planned outage as part of its (re)commissioning process.

A running view of the recent wind drought
A view of cumulative total wind production in Q2, highlighting a lack of spatial resource diversity, and the future challenges for gas and long-duration storage.
A similar trended view of the aggregate production from Coal-Fired Generation across the NEM through 2024 Q2
Taking the ‘worm line’ cumulative trend recent Q2 periods (used for wind, hydro and gas-fired power), we now apply this to coal-fired generation during 2024 Q2.
A similar trended view of the aggregate production from Gas-Fired Generation across the NEM through 2024 Q2
Taking the ‘worm line’ cumulative trend recent Q2 periods (used for wind and then hydro), we now apply this to gas-fired generation during 2024 Q2. We see two distinctly different patterns … early in Q2 and late in Q2.

CS Energy has released the latest draft of the ‘Brady Report’ – a draft Executive Summary, a draft Part A (Technical) and a draft Part B (Organisational)
A similar trended view of the aggregate production from Hydro Discharge across the NEM through 2024 Q2
Taking the ‘worm line’ cumulative trend recent Q2 periods (first used for wind), we now apply this to hydro during 2024 Q2 to see to what extent hydro production volumes are lower than recent (and other notable) years.
Where’s the wind gone, through 2024 Q2? … with June perhaps even worse than April or May!
Extending the ‘worm line’ cumulative trend of wind production through 2024 Q2 (to 22nd June) and comparing to 2023, 2022, 2021 and 2020 reveals a picture that is, at the same time, both frightening … but also completely expected (at least for some).
Trended bids (and production) from gas-fired generation over the past 90 days
A short article looking back 90 days at production volumes, and bid prices, from gas-fired generation.
