Hot day in Sydney, hot electricity prices

5 February 2026

Just as during question time in the comfortably airconditioned Parliament the price of electricity was discussed in its umptieth iteration ……………

Mr CHESTER (Gippsland) (14:42): My question is to the Minister for Climate Change and Energy. The minister has had several opportunities in question time this week to explain when Australian families can expect the $275 reduction in their power bills promised by the Prime Minister. Will the minister finally admit the Prime Minister wasn’t telling the truth and not a single Australian family has seen the $275 reduction? Minister, why can’t anyone in the Labor Party accept responsibility and just say ‘sorry’ to the Australian people, who are struggling under Labor’s cost-of-living crisis?

Mr BOWEN (McMahon—Minister for Climate Change and Energy) (14:42): I thank the honourable gentleman for his question. I take responsibility for the energy system in Australia. I take responsibility, as the minister, for progress. I take responsibility for dealing with the headwinds and the setbacks. That’s what a minister does. A minister takes responsibility and deals with it—doesn’t hide. Electricity rises before an election, for example. That’s an option. That is an option available to a minister. That’s not an option that I’ve chosen to take. I take responsibility for the progress. I take responsibility for dealing with the setbacks. I take responsibility for the more than a thousand batteries that have been installed in the honourable member’s electorate, the 1,139, that have been installed in the member’s electorate since 1 July. I note that, in Victoria, the wholesale price of energy in May 2022 was $233 a megawatt hour, and today it is $37 a megawatt hour. I do take responsibility for all the above.

………. there was a price spike in NSW of $9,200/MWh after prices had already hit $20,000/MWh just 20 min earlier:

Fig 1: Price spikes in NSW on 5 Feb 2026. Max demand was around 12,100 MW at 4:20 pm

https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem

$9,200 / MWh is $9.20/kWh (wholesale). The average over 24 hrs was $ 406/MWh. The average lower than the price cap of $600/MWh was $150/MWh. The price cap was exceeded for 1.6 hrs. What does that mean for retail prices? Let’s make the following back-of-the-envelope calculation:

Assume a customer is paying 25 cents/kWh retail and the wholesale component is 40% that would be 10 cents. The other components would be 15 cents. The $150/MWh below the price cap would be 15 cents/kWh. So the retail price would be 15 cents + 15 cents= 30 cents
If there is 1 hot day per week with 40 cents/kWh wholesale then retail would increase further by (40-15)/7 = 3.6 cents. Total 33.6 cents/kWh.

A windless, cloudy, hot afternoon required early ramp of hydro, gas and coal long before sunset.

Fig 4: The afternoon was cloudy with an early drop in solar power

Fig 5: Clouds moved over Nevertire solar farm starting at 1 pm

Note also in Fig 3 the sudden need to export power to Victoria starting at 2 pm because there was a drop in solar power there.

There was also a problem with the Avon – Marulan 330 kV transmission line

Out of the 12 coal power units, 3 were offline.

This reserve notice was cancelled at 5:48 pm (notice 133311)

The mainstream media did not report about the price spikes so the public is unaware what happened and what the causes are. The opposition sometimes mentions possible power shortages but this is seen as a political stunt. So there will be a surprise when it really happens as a result of various factors coinciding.

Vales Point showing unplanned outage

You can tell it’s an unplanned outage by the time the outage happens, in this case at 1 pm, in the middle of the day. Planned outages would usually start at night due to lower demand.

Another price spike on the 7th Feb 2026
