Everyone drives a hybrid which

He would also set the power rates at lower amounts at off peak
times and higher during the daily peaks.

For this to be meaningful, the consumers have to see different
rates for peak usage and non-peak usage. The utility company told
us to pump the pool at night (supposedly non-peak usage), but we
are paying the same either way. Only total kilowatt hours matter
anyway.

Didn't I mention that? This guy would require the power company to
both sell and buy at prices dependent on the gross usage compared to
peak.

Turns out the power company here charges based on your peak usage. A
friend works at a dairy which has many electric motors, some of them
quite large. They paid thousands of dollars for control panels that
will bring the motors online sequentially to prevent a huge spike in
the power consumed. This saves them money because their rate is set
by the peak usage at any time during the day.

That is another way to save money, if the power companies start
charging residential the same way they charge commercial, the hybrid
can kick in to supply current during the peak in your residence. But
then most people are away during the day anyway. I guess the AC
still runs.

You still want to keep the house dehumidified during the day.

I recently interviewed with a company that makes smart power meters.
They can control loads, so the power company can level loads without
blacking out everything. For instance, I doesn't matter much if a
water heater is turned off for a few hours, or the water heaters
across town are cycled. Much better to turn them off for some hours
during the day than have large peaks. The meters network with their
neighbors so metering and control can be done across wide areas.
Slick stuff.


how does the power meter control your WH or other in-house loads?
It would have to have a device wired into the WH and other loads.
(some may just plug in.)

My local power company offers a thermostat that they can control to shut
off your AC during peak power demand periods.
