California Utilities to Control Thermostats?
TeraBill writes "It seems that the California Energy Commission is looking to give utilities in the state the power to control the thermostats in private homes via a radio signal. The idea is that during times of significant energy crunch, the utilities could force thermostats to higher temperatures rather than having to implement a rolling blackout. The thermostats have been around for a while and new ones were on display at the CES show in Vegas this week. While I can see the argument for it, we just had a kid take over a tram system with a remote control, so how long before our thermostat gets hacked by the neighbors. And I'd almost rather have the power drop than have someone significantly raise the temperature in my home if I had a computer running there. (UPS and a graceful shutdown versus cooking something.)"
They already have a system like this in place in south Louisiana, some electricity co-ops use load management terminals, which look like a separate electric meter connected to the air conditioner. On hot summer days, they'll shut off the A/C for up to half an hour, to prevent overload to the grid and save money. They don't shut everybody's A/C off at once, they "roll" the shutoffs through the neighborhoods. It can be a bit of an inconvenience because of the temperature rise in your house, but if your house is well insulated, you won't notice it that much. The system is totally voluntary, and you even get a minor rebate on your electric bill.
