The Peak Time Savings program works to ease energy demand without sacrificing comfort by syncing with your home’s smart thermostat to make slight, temporary adjustments during demand response events. These events are periods of high electricity demand when energy prices are higher than usual. By anticipating these demand response events and pre-cooling your home accordingly, Peak Time Savings ensures that you stay comfortable throughout the event. Plus, you're always in control of your thermostat and have the option of opting out of events.*
