Colorado Utility Took Control Of Thousands Of People’s Home Thermostats
Xcel Energy prevented thousands of customers in Colorado from changing the temperature in their homes for hours on Tuesday due to an "energy emergency."

Yes, but they could only cut your unit off for a few minutes at a time via the weird box they installed on it.GD I am sure you are familiar with this. Power companies have done this for years if you are on certain energy saving programs. Technology allows control through smart thermostats now. Back in the day they put a radio controlled (sometimes LAN line controlled) relay directly on the condensing unit. With a signal the contactor would kill power to the condensing unit to reduce over all demand. I don't remember if the relay killed the fan and or just the compressor. I always thought it was a bad concept to interrupt power regardless of what stage the unit was in. I have seen the life of the compressors shortened by this device. Kind of big brotherish but people signed up for it to get rebates or discounts.
