The NEM ran through a mixed 24 hours on Friday, with overnight demand peaks driving prices into the $90–$113/MWh range in Victoria between 17:00 and late evening, while Queensland traced a pronounced overnight trough that briefly touched negative territory before recovering to $84.50/MWh by 06:25 AEST. South Australia held firmly above $100/MWh through much of the day — reaching an overnight peak of $142.66/MWh — despite relatively modest demand around 1,394 MW. Tasmania recorded its day peak at 1,354 MW around 08:10 AEST, easing back to 995 MW and $80.20/MWh by mid-morning. Interconnector flows are shaping clear regional price separation today; watch the Heywood link (V–SA) and Victoria's export position as the Saturday load profile develops.
Tasmania delivered two headline events in a single day. During the 20:05–20:30 period, the region achieved 100% renewable generation — hydro (~885.6 MW) and wind (~234.4 MW) supplying full demand with no thermal dispatch, and regional reference prices holding flat at $80.20/MWh. Separately, and more notably for network operators, a binding constraint T_BLINK_TV_NGZ registered an exceptionally high shadow price of $7.308 million during the early morning period — signalling significant internal network restriction despite otherwise modest spot prices. The constraint is the key operational detail to carry into the weekend.
The Wholesale Electricity Market was the highest-priced region across all six markets over the past 24 hours, averaging $136/MWh with a daily maximum of $306/MWh. A single-interval price spike to $263.34/MWh occurred at the 03:55 trading interval, up sharply from $247.67/MWh in the preceding settlement. The event occurred during the night-time window when solar output was absent. No further multi-interval spike sequences were recorded; conditions appear to have stabilised through the morning.
