Australian wind energy sets new record of more than 3,200MW at midnight on Saturday.

During the past week, we helped Giles Parkinson post this article noting that wind farm output had reached 2,988MW as a new record (higher than what we saw over summer 2014-15, for instance).

On Sunday I noticed that, in the quiet of the night, wind output had roared along and peaked at 3,215MW in the 00:05 dispatch interval (meaning metered generation output measured at 00:00 leading into Sunday).  This point in time is shown in the following snapshot from NEM-Watch v10 (using “Playback” to reset the display to how the market looked back at that time):


This represented about 16% of the Scheduled Demand Target used by AEMO in dispatching the market:

However note that:

1)  this is not a correct measure, strictly speaking, as some of the wind output is non-scheduled, so nets off Scheduled Demand – the real percentage would be somewhat lower than this).

2)  also note that demand around midnight is being inflated by off-peak hot water load in South Australia, and that (more generally) demand does not reach its low point across the NEM until around 4am each morning.

The above, however, is indication of how the latest projects added to the grid late in 2014 are contributing to the increased output.

Continuing into this afternoon, we see that the high wind output has continued (though slightly lower) and has been one of the factors delivering very low Scheduled Demand levels across the NEM, and also very low prices – negative in places:


If it’s true that the political argy-bargy over the RET target is closer to resolution (not withstanding the latest political point-scoring shenanigans) then this is the type of thing we might be seeing much more of in the years ahead to 2020.

    SA wind production still going and you can see the uptick at midnight due to off-peak “controlled load” hot water systems. ( for the latest charts)

    It looks as if controlled loads such as water heaters could be better “controlled”. I know that most electric water heaters only need about three hours to heat a normal size tank and careful examination of the second NEM Watch snapshot confirms this. In fact, due to residual hot water in the systems, it looks like the controlled load profile is even shorter than 3 hours. So why not stagger controlled loads instead of them all coming on together?? Or should they be called uncontrolled loads?
    I recall several years ago the transmission line to Balranald needed to be replaced and its peak design load was then the controlled loads euphemistically called off peak loads! I understand the peak design load was reduced by using solar water heaters and staggering the “controlled” loads.

    If wind power reduces power costs then I’ll say HEY! It Wont…I paid extra 50 per bill for years till I stopped.. Im ashamed of the desecration of lands too.
