hmmm - should read "wind farm distance from coastline."

to simplify - it says "go inland, go north for best returns on wind farm investment."
all about inland nocturnal wind intensification associated with the development of heat toughs (aka drylines).
No reason to suspect we have anywhere near the best sites to pick up low level nocturnal jets!

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.

so would appear Rhodos is tilting north down, south up - which is not at all surprising given it sits above the eastern end of the Aegean slab. (Nice earthquake record on the south coast)

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

@msandifo.bsky.social

partly because southern coast wind production shows little diurnal variability ...
Mike Sandiford
@msandifo.bsky.social

presumably - also reflecting the increases in economic curtailment of wind, which is an emerging issue especially for southern coast wind farms ...

whereas the former is dominated by southern ocean storms, the latter is dominated by low level nocturnal jets associated with the development of the northern Australian dryline.

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.
