AEMO directs load shedding (following unplanned network outages) in NSW on Monday evening 8th July 2024
A short (perhaps initial) record of load shedding instructed for NSW on Monday evening 8th July 2024.
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.

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).
