CAMMESA administers the Argentinian electricity market, and they have data on demand [1] and grid flows. Compare the graph of flows on the 500 kV lines from 2019-06-16T07:00 local [2] to one hour later at 08:00 local [3]. For reference, see the prior day too, at 2019-06-15T08:00 local [4].

I don't understand why BsAs temperature would drop just because the e got knocked off, or why it ceases to be an analog function after the cut :S

  My guess would be that it's an average of several temperature sensors, and that a sensor going offline registers as zero. So when the sensors come back online, there's a sudden jump in the calculated average temperature.

    The power drops so often that Argentina would be quite a bit warmer than officially registered here if it were true.

[2] and [3] refer to June 15; [4] refers to June 16. Is your text correct? What can be learned from the numbers on the 500 kV lines?

  If you change the links to june 16th, you'll what they were trying to say: http://www.cammesa.com/uflujpot.nsf/FlujoW?OpenAgent&Flujo%20Geografico&16/06/2019%2007:00 http://www.cammesa.com/uflujpot.nsf/FlujoW?OpenAgent&Flujo%2... http://www.cammesa.com/uflujpot.nsf/FlujoW?OpenAgent&Flujo%20Geografico&16/06/2019%2008:00 http://www.cammesa.com/uflujpot.nsf/FlujoW?OpenAgent&Flujo%2...

    Good catch, the links in my previous post are not accurate. The correct links for [2][3][4] are: [2] http://www.cammesa.com/uflujpot.nsf/FlujoW?OpenAgent&Flujo%20Geografico&16/06/2019%2007:00 http://www.cammesa.com/uflujpot.nsf/FlujoW?OpenAgent&Flujo%2...

The 500 kV lines form the backbone of Argentina's power grid. The drastic fall in power flows shows the massive shedding of load and generating capacity, as presumably plants disconnected from the grid for safety. One can step through the next few hours to see how generation was restarted.
