When did you install Sense?
From that .csv (thanks for sharing) it looks like you’ve had a month of brownout conditions.
I’m not familiar with PA ISO GUIs but a quick search got me here:
With the right metrics my guess is you could analyze the NY ISO real-time load interface and predict brownouts, unless of course they behave like CA seems to be doing right now and arbitrarily knock back the voltage based on the grid supply cost rather than actual overload.
@JustinAtSense’s recent response to a similar issue is very informative and worth a read:
