I’ve not yet had time to fully investigate, but thought it worth recording the sharp drop in frequency that appears to have occurred shortly after 07:30 NEM time on Friday 13th June 2025.
Friday 31st January 2025 (appeared to) experienced a very large drop in demand in NSW in a single dispatch interval – but we’re now suspecting some form of data/operational glitch. However we wonder, if there was ~1,000MW more energy injected into the grid than required over a sustained period, what stopped the frequency flying through the roof?
In this article we inspect power deviations from dispatched units that would have contributed to the frequency rise, and the deviations that would have contributed to the correction.
