Queensland set two new instantaneous power generation records on Sunday March 15. First, the share of wind in the state\u2019s grid hit a new high of 29.6 per cent just before four o\u2019clock in the morning (3:55 am) and second, battery output hit a new high net share high of 16.6 per cent at 6:15pm.<\/p>\n

The timing is instructive: The wind record was set in the pre-dawn period, while the battery record was set in the evening ramp. It\u2019s a reminder that different technologies are now shaping different parts of the Sunshine State\u2019s demand curve. <\/p>\n

The same Sunday also saw meaningful daytime curtailment of renewables generation which, based on the chart\u2019s average curtailment of 335 megawatts (MW), implies about 8 gigawatt-hours (GWh) of curtailed energy across the day.<\/p>\n

With prices around -$8 per megawatt-hour (MWh) through the daytime curtailment period, this looks to have been mainly economic curtailment, rather than a scarcity-driven operational event.<\/p>\n

Another notable datapoint for the day is that the Queensland flexibility premium (battery discharge price less charge price) was only $80\/MWh. So while batteries set a new output-share record in the evening, the intraday spread was still relatively modest against the level of midday surplus.<\/p>\n

Taken together, the day shows three things at once:<\/p>\n

\u2013\u00a0Strong overnight wind contribution;<\/p>\n

\u2013\u00a0 Strong evening battery participation, and;<\/p>\n

\u2013\u00a0Continued midday surplus \/ curtailment pressure in the solar window.<\/p>\n

All told, it\u2019s a useful snapshot of how the Queensland supply mix is evolving across the full day, not just at the daily peak in renewable output.<\/p>\n
