In Brisbane, Australia 35 years ago we had a reduced rate for our electric water heater. The utility authority (the City, as it happened) could switch it on and off any time they wanted by sending the appropriate sequence of audio tones superimposed on the line. If we still needed to heat water during one of the high-demand periods when the reduced-rate power was off, we could flip a switch and heat our water with standard-rate power.

No RF imposed on the power lines to radiate all over the place. All that would be necessary to enhance the system would be to use different audio receivers responsive to a variety of tones.

If BPL gets deployed, we'll need some ECM.

Since BPL advocates occasionally cite energy management as a rationale
for deploying BPL, its a useful topic to understand. They don't push
very hard on this, and I've never found anything substantive behind
their references. I beginning to think its mostly smoke.

Offering electricity users lower rates for off-peak usage would be a
win-win for everyone, and requires only that the house meter be
appropriately upgraded; being able to read this meter via the internet
would save some labor costs and provide more convenient real-time
readout to the consumer, but any network connection -- BPL, cable, or
DSL -- could provide this. Pay-per-view satellite receivers use
telephone lines to report usage information.

Sorry. Jetlagged. That was supposed to be EMC...as in electromagnetic compatibility. As opposed to ECM, which is electronic countermeasures.

You make a good point about retrofitting appliances. I would suppose
that being able to add wireless isolated metering/monitoring to the
electric, gas, or water supply would be a pre-condition. Control of
heating system and lighting, either automatically or remotely could have
value for some
I can't imagine that having appliances interfaced would add value to my
life. Coffee maker? Frig? Stove? Interfaced pantry reporting stock
levels of items and generating a shopping list? I don't think so. This is a major digression in one sense...but may be important to
understanding what's driving the power industry's investment vision.
I haven't read enough yet to see what their magic motive is for BPL. n2ea
