One of the most intriguing diagrams I have produced in a while ... at least for NEM/RE aficionados.
N* (y-axis) is ratio of midnight ± 3 hours to midday ±3 hours generation for QLD, NSW and VIC wind farms over the 12 months to end June 2025.
x-axis is wind farm dance from coastline.

which contrasts inland wind which has a prominent nocturnal peak*, and therefore will suffer less economic curtailment (but currently lacks transmission ...) *best exemplified by QLD but is true also of inland NSW and VIC

The complimentarity between inland nocturnal winds and daytime solar, especially so in central Queensland (and I suspect inland NW WA), there should be much to excite new investment … and provide new guidelines for appropriate transmission investment to capture the opportunity.

So what gives? Why does nocturnal wind generation correlate with diatnce from coast? Has to do with the development of low level nocturnal jets associated with inland drylines, as invetsigated by Arnup and Reeder "The structure and evolution of the northern Australian dryline”, amongst others.

Similar relations hold for the Victorian farms. Turns out the further inland you go, the more the wind farms produce at night.

So what gives with wind farm production? Here is the yearly average by time of day for NSW and QLD wind farms (expressed in capacity factor terms) and ordered by distance from the coast.
