Report photo voltaic era from large-scale and rooftop PV is driving wholesale power prices, lowering emissions to file lows, and serving to set new information for minimal demand for electrical energy from grid, based on the Australian Vitality Market Operator (AEMO).

New highs in renewable power era, together with file common output from rooftop photo voltaic, resulted within the lowest demand within the Nationwide Electrical energy Market (NEM) within the March quarter since 2005, based on AEMO’s newest market intelligence report.
AEMO’s Q1 Quarterly Vitality Dynamics report exhibits that the common output of rooftop photo voltaic reached a file 2,962 MW within the first three months of 2023. The market operator mentioned that this elevated by 23% in comparison with the identical interval in 2022, which exhibits the continuation of excessive distributed PV set up development charges after slowing down in 2022.
Technology from large-scale photo voltaic and wind surged within the quarter by a median of 330 MW and 134 MW, respectively, giving a file quarterly common of 4,654 MW, which is 11% greater than the identical interval in final yr. The expansion in grid-scale photo voltaic and wind output is attributed, partly, to new and just lately commissioned items coming on-line.
AEMO reported that the file photo voltaic era resulted in a fast penetration of the renewable power peak at 65.8% within the quarter, however it’s normally about 37% of the full electrical energy era. On prime, up 4.4% on the earlier file, rooftop photo voltaic accounts for 36% of provide.
On February 11, 2023, rooftop photo voltaic output peaked, reaching a file excessive of 11,504 MW, up 818 MW from the earlier excessive reached within the fourth quarter of 2022.
AEMO Chief Government Officer Daniel Westerman mentioned the findings spotlight the elemental modifications underway as Australia’s power system transitions from fossil fuels to renewable sources.
Nevertheless, Westerman mentioned the report additionally reinforces the necessity for extra funding in new transmission infrastructure and “firming expertise” to assist the grid address the swap, as a number of main tasks within the -or power within the Murray area of Victoria and south-west NSW. unable to offer their full capability to the grid resulting from transmission community constraints.
“These views reinforce that essential investments in transmission, corresponding to VNI West and EnergyConnect, are wanted to share low-cost, low-cost renewable power with shoppers,” he mentioned.
“That is clear from the tasks in Victoria’s Murray River renewable power zone which are burdened by the consequences of era.”
Regardless of curbing issues, the expansion of renewables has helped ship new information for minimal demand, pushed wholesale electrical energy prices to historic ranges, and helped cut back emissions to to file lows as coal-fired and fuel era declined.
Report ranges of photo voltaic era contributed to the bottom working demand within the first quarter of the yr since Tasmania joined the NEM in Could 2005, at 14,375 MW.
AEMO’s report confirmed operational demand fell to 21,181 MW, the bottom first quarter common since Tasmania joined the NEM in 2005. The brand new determine was down 1.5% on the identical interval final yr. . Operational demand fell on 21 January 2023, reaching a file low of 14,375 MW within the half hour ending 12.30pm.
“The expansion of renewable output throughout the NEM means 12% in the course of the interval when wholesale costs are adverse or zero. As well as, between 9.00 am and 5.00 pm, wholesale electrical energy costs are adverse in South Australia and Victoria 60% and 55% of the time, respectively,” Westerman mentioned.
The report additionally confirmed a March quarter file low for greenhouse fuel emissions at 28.83 million tons, down 5.1% from a yr earlier as electrical energy era from coal and fuel declined.
