Smart Cooling Rewards.. from the site..

Dominion will install an A/C cycling switch on your home’s outdoor cooling system. Since the work is performed on your outdoor unit, you don’t even need to be home during installation. We provide the equipment and the installation is free.
During periods of high electrical use, between June 1 and September 30, Dominion may cycle your home’s cooling system on and off at defined intervals. Your fan will stay on, circulating already cooled air.
Cycling times are limited to weekdays (no weekends or holidays) typically for 2-4 hours between the hours of 2 p.m. and 6 p.m.
