Oh No!!

Not going to bother opening the link to read that, so I'll make an edumacated guess that the customer had signed up for load shedding service in exchange for a lower rate. Our POCO offers that service too. One day the area's consumption was close to 100% and the POCO decided to shed some non-critical loads for awhile so they signalled AC off, consistent with the customer's agreement that allowed it during a power shortage. So what's the mystery? Where's the evil crime?

Southern California Edison, (SCE), is the provider here. The smart meters can be read with a 24 hour delay. You simply access the SCE website with your account. It shows your usage by the hour for the previous 24 hours. The meter simply supplies information via a friendly computer generated report that is VERY clear and simple.

The meter has no power in controlling your usage. However, I do not recall if that was or was not an option for it to do so. I don't think so. However, by default it did not control it.

What I've described above is as good as it gets by my standards.

SCE has the Summer Discount Program (SDP). They come and install a box on your AC that gives them the option to control it. The've had this program for several years, well before smart meters. It has been great (saving an easy $40/mo during summer) up until last year. They got really carried away, cycling it on moderate days when the CA-ISO showed no shortfalls.

Edison is not forcing smart meter customers onto TOU rates, at least not yet.

The smartmeters installed by PG&E have the ability to communicate with (and control) electrical equipment in your home (using ZigBee home automation protocols) however for now this ability is not enabled. The stated goal is to provide a public website where the homeowner can use PG&E's smartgrid to control his/her appliances remotely. My expectation is that at some point in the future we are given a choice to either turn off some appliances at periods of high demand or keep them running at a premium rate (which I have no problem with as long as I get to make the choice).

The smartmeter can also communicate with an AC load shedding device (two options: disconnect relay or set-back thermostat). Those devices are optional but customers agreeing to install them will get a reduction on their monthly bill. I believe this option is just an interim solution until more elaborate controls are developed.

I suspect you were affected by San Onofre going off-line in January 2012, and I wouldn't be surprised if the frequency of cycling increases this summer, too.

Up here in the Central Valley SCE has not noticeably cycled our A/C in a long while. A few years ago they got so carried away with the program that we nearly dropped out, though. Location, location, location, I guess.

Our meter does seem to incorporate a real time use display, which seems like an obvious good thing for any meter to employ. There has been no change in our bill since the installation of the meter. I have been impressed that in an area where cell phone connectivity is poor (to say the least) the meter seems to manage.

Exactly!

This has NOTHING to do with smart meters. It is a remote override system that you opt into.

Indeed, absolutely nothing to do with smart meters. Such devices to remotely turn off large non-critical loads have existed for several decades before the concept of smart meters was even invented.

The earliest of devices were purely electro-mechanical. The utility would inject a high frequency signal over the power lines to which the switching device would respond by either turning on or off. No electronics involved at all. Not exactly sure how they did it, probably some type of vibrating reed that would resonate at a specific frequency.

Here's a video of one of those ripple injection motor-generator sets running:

I don't know what's on the receiver end, but the above system must have some sort of active electronics, since it's a coded pulse train that's delivered (based on the sound of the motor). I guess a simpler system could exist where the load device just filters for the signal frequency and closes a relay with the filter output.

Very interesting stuff. I poked around a bit and was disappointed to find there is very little information online pertaining to how the ripple control receiver works. This may be because they were not widely deployed in the US.

However I was pleased to learn that in South Africa, a domestic water heater is called a "geyser".

The smaller on demand heaters get called that in Ireland and Australia. In Ireland they pronounced it Geezers.
