Hi,
It's based on UTC, as derived from GPS.
I think you will find the following NASPI report of interest:
https://www.naspi.org/node/608
You will find maps over the regions too!
While NASPI is PMU/synchro-phasor focused, older equipment use GPS too
for phase capture.
Cheers,
Magnus

I was wondering if anyone knew how the US power grids control their line
frequency with respect to time ?
There seems to be four separate grids - Eastern, Texas, Western and Quebec -
but I have no idea how they get their time.
