Arizona Utility Company Testing System That Lets Them Control Home A/Cs

Arizona Public Service Co (APS), Arizona’s largest power company, is implementing a test program that would put customers’ thermostats under their control to help balance power needs during critical peak usage times. APS will be able to remote control the customer’s thermostat to control power draw from their A/C when there is a critical power transmission issue on the grid. Customers will be able to override these settings if they desire.
