Looking forward to paying 62% less for electricity when this is implemented ...
SLAP!

I was a lead engineer designing electric substations for almost 40 years before retiring. I hope the high tech solutions outlined in this article can be implemented. The reality of what I see makes me somewhat skeptical however. Some basic grid info. Every power transformer has impedance of which some is pure resistance. The power lines obviously have some pure resistance. Substation circuit breakers are rated as 2000 or 3000 amp. Many times running that high that but still 1000 amps is not uncommon.
We always ran overheating calculations at peak loading of transformers, breakers, bus, etc. This heating is all watts loss from the high current thru the low but real resistance. All of that will remain regardless what the new technologies try to do with other portions of the electricity use.
Good luck to them as they optimize the grid. It needs optimizing but there may not be the level of efficiency they think available.

On an "At the Wallplate" level, bluntly, nothing needs "optimizing" unless it is an AC motor. That is what power-supplies do. And AC motors are such sloppy devices anyway, they just don't care that much unless the power is really wretched.
