Australia’s vitality market operator says batteries are more and more supporting demand peaks within the National Electricity Market (NEM). The common technology throughout these instances has doubled for the reason that similar time final yr.

The Australian Energy Market Operator’s (AEMO) Quarterly Energy Dynamics report confirmed battery contributions to fulfill the every day most demand of NEM operations elevated to 1.3% within the second quarter, up from 0.5% within the second quarter. in 2023.
AEMO’s quarterly report confirmed that chilly climate pushed the NEM’s demand file within the second quarter, reaching a most operational demand of 32,322 MW on the night of June 24, a 2 MW improve from the utmost of 32,320 MW in second quarter of 2023.
Weather situations additionally noticed much less wind and rain within the southern states, decreasing wind output by 20% from final winter and an 18% discount in hydro mills. In distinction, gas-fired technology elevated by 16% in comparison with the identical interval final yr.
Battery manufacturing has additionally elevated with AEMO Chief Executive Officer Daniel Westerman saying market situations spotlight the important thing position expertise will play as renewable technology turns into more and more dominant on the grids. of electrical energy in Australia.
“On the east coast we’re seeing decrease temperatures and continued chilly snaps, significantly in Victoria, driving increased morning peak calls for by the tail finish of autumn and the primary month of winter, ” he stated. “The position of batteries in supporting morning and night demand peaks has develop into extra outstanding, with the typical technology instances greater than doubling since final yr, displaying a major improve in battery capability. “
AEMO stated that battery technology throughout the morning operational peak averaged 138 MW throughout April, May and June, greater than double the 67 MW recorded within the second quarter of 2023. of 128 MW from final yr. . At all hours of the day, battery technology averaged 74 MW within the second quarter, an 89% improve over the 35 MW recorded throughout the identical interval final yr.
The rising position of batteries gives extra income for operators with whole estimated internet income for NEM grid-scale batteries this quarter rising to AUD 41.2 million ($27.22 million), a rise of AUD 13.6 million from AUD 27.7 million in internet revenue earned within the second quarter of 2023.
AEMO stated the primary driver for the elevated internet revenue was the advance in battery capability and availability, with the NEM-wide common quarterly battery technology availability nearly doubling from 496 MW within the second quarter of 2023 to 985 MW this quarter.
As the position of battery vitality storage methods elevated, distributed PV and grid-scale photo voltaic output additionally elevated within the second quarter. Grid-scale photo voltaic technology averaged 1,417 MW, a ten% improve from 1,285 MW within the second quarter of 2023, primarily as a consequence of elevated output from new and commissioned services.
Distributed PV output reached the very best quarterly common on file, reaching 2,050 MW, up 163 MW from 1,888 MW within the second quarter of 2023.
Wholesale spot costs averaged AUD 133/MWh throughout the NEM this quarter, up 23% on the identical interval final yr. Regional reference costs vary from AUD 173/MWh in NSW to $101/MWh in Queensland
In Western Australia costs remained comparatively flat, averaging AUD 79.79/MWh, up AUD 0.30/MWh from the second quarter of 2023. AEMO stated rooftop photo voltaic technology within the Wholesale Energy Market (WEM) elevated by 49 MW within the second quarter as a consequence of sunny. situations and improve in put in capability.
