Those links are very informative. Can you elaborate on Ancillary Services Monitor and Energy Storage Resource Action dashboards? What’s the installed capacity that supported?

Also your original post link states event happened at 7:02 AM, your links here points to 8:05 AM. Can you explain this?

You may need to check the time zone as some pages automatically adjust to local time of your browser. It happened at 7am CT.

That makes sense, I'm in EST.

Just to clarify and understand what happened, I believe right after the trip some generators all around the grid picked up the load (unless UFLS was activated) immediately (around 7:03), we can call these generators support system. Then around 7:05 batteries kicked in with 468 MW, as a support to support system.
