Hornsdale Power Reserve Battery operation on Tue 28 May 2019

It has been observed that the Hornsdale Power Reserve Battery operated on Tue May 2019 in a way not previously seen. This behaviour is shown in the graph below.

It is unusual to see the output above 30 MW, both charging (green line) and discharging (magenta line), and there are only a hand full of days since it's commissioning where the output has exceeded 30 MW (15 Dec 2017, 24 Jan 2018, 30 Aug 2018 and 27 Nov 2018 ). It is also unusual to see such extended periods of continuous discharging and charging.

The Hornsdale Wind Farm outputs are also shown on the graph - Hornsdale Wind Farm 1 (blue line), Wind Farm 2 (red line) and Wind Farm 3 (Yellow line).

The black line shows the curtailment of SA semi-scheduled generation. We can see that at times the curtailment reduces when the battery charges. It would appear that battery could be being used to control curtailment of semi-scheduled generation in SA, be it their own or other windfarms?

The Hornsdale Battery Daily Summary is shown since the 01 Dec 2017, along with the SA FCAS Raise and SA FCAS Lower for Tue 28 May 2019 (not a lot happening with the FCAS prices).
