"For a half hour in the middle of a Saturday last month, enough renewable
energy was available to meet all but 1.4% of eastern Australia’s entire
electricity demand – the closest to reaching 100% clean power in the grid’s
history.
Renewables also supplied 38.9% of average demand across the national
electricity market (Nem) in the September quarter, the most for any third
quarter, according to a report by the Australian energy market operator (Aemo).
Total carbon emissions from the power sector, Australia’s biggest single
source, were down 11% on a year ago. The share of generation from gas fell by
almost a third and black coal by 7.5%, even though both fuels were slapped with
price caps this year by the Albanese government.
Sunny skies as rain clouds disappeared contributed to an abundance of solar
output, driving prices on the wholesale spot market negative for 19% of the
time. That proportion was more than double that of the September quarter of
2022, and smashed the previous record 9.2% share in the June quarter of this
year.
For the September quarter, wholesale power prices in the Nem averaged $63 per
megawatt hour, down 41% on the previous three months and 71% lower than a year
earlier, as Guardian Australia reported. Average wholesale gas prices on the
east coast cratered to $10.41 per gigajoule from $25.94/GJ a year earlier.
Wholesale price reductions, though, would need to be sustained to make much
difference to households’ retail energy bills. These are typically set
annually."
