The North American Power Grid consist of four grid interconnects:
Eastern
Western
Texas
Quebec
Each grid is composed of 10 Regional Reliability Councils, they all
report to the North American Electric Reliability Council or NERC.
All are interconnected and indeed ship power back and forth as
needed across the whole grid. I believe we even have interconnects
with Mexico now, though I am not sure on this one.
====================================
What I was trying to say was that a system syncronized from one reference will not appear syncronized from another place, because the size of the emitter is large compared to a wavelength (at 360 Hz, even at 50 Hz).
So in syncronizing were based on a signal from WWV in Colorado USA we would see from the moon neat looking ripples propagating away from there.
If the timing is based on some universal time (so it would be syncronous seen from the center of Earth), the phase near the limb of Earth would still lag by up to Earth's radius, and this might be erasing the strobing effect on the Moon...
