Low aggregate wind yield after sunset continues – Sunday 26th May 2024

Continuing the pattern of low aggregate yield from Wind Farms right across the NEM just after sunset (i.e. when ‘Market Demand’ peaks, but when the input from Solar Farms have disappeared) we see wind yield, after ramping up slightly compared to the just before sunset at 522MW NEM-wide at 17:45 (i.e. aggregate InitialMW for 17:40), as captured in this NEMwatch snapshot at the time:

This follows the pattern of low wind yield after sunset seen documented on Thursday 23rd May and Friday 24th May and Saturday 25th May … which seems quite remarkable?!

1)  with 11,403MW installed capacity of Wind Farms right across the NEM (notwithstanding these complexities of measuring installed capacity) that works out at an instantaneous Capacity Factor of just 4.6%.

2)  fortunately, NEM-wide ‘Market Demand’ is only low (just below 27,000MW), or we’d likely see higher prices.

Looking forward to finding times to look into this more statistically …
