QLD Market Demand reaches 9,512MW on a hot Sunday afternoon–12th February 2023

We’ve recently written a number of articles about what happened in QLD on Friday 3rd February 2023, where Market Demand reached 9,806MW at 16:55 … but how this was almost 1,000MW below what prior expectations had been,:

1)  A sizeable ‘miss’

2)  With a cool weather change ‘to blame’ for forecasts not matching reality.

As Linton noted on Friday, there’s a significant cost that energy users will pay for the RERT contracted and triggered on that afternoon – and some might look at the distance from forecast as indication of some ‘error’ on the part of forecasters at the weather providers and/or the AEMO.

So it’s worth noting that 9 days later (on Sunday 12th February 2023) we saw Market Demand reach 9,512MW at the 17:35 dispatch interval – as captured in this NEMwatch snapshot at the time:


This level:

1)  was only 294MW below the point seen on Friday 3rd February 2023 … and

2)  was 609MW below the all-time maximum (up at 10,119MW back on 8th March 2022).

At 18:44 (~70 minutes later) the AEMO, via MN105809, flagged an Actual LOR1 condition as follows:
