I use the NOAA space weather dashboards
https://www.swpc.noaa.gov/communities/electric-power-community-dashboard
Also Spaceweather.com http://spaceweather.com/
Solar Ham also aggregates a ton of space weather data http://solarham.net/
Geomagnetic storms are not uniform. (Think aurora – like a wind – it moves and shifts and does not stay in one place.) They are measured at specific terrestrial locations, Boulder CO I believe is one of the sites, and Tromso, Norway. In my opinion there COULD be a localized overcurrent in the electrical transmission system caused by geomagnetic activity. But such overcurrents are more likely to be observed in the far north like the Canadian incident a few decades ago. (In the same places where strong auroras are observed.)
That being said, I don't believe the NY incident was caused by a geomagnetic storm, but can't totally rule it out either. We'd need data about Con-Ed's network and instrumentation measurements, which is not available to us and never will be.
So I'm just shooting from the hip based on probabilities and personal observations. Take it for what it's worth (not much).
