said by djrobx: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.
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.
