Installed in refrigerators, air conditioners, water heaters and various other household appliances, this device would monitor the power grid and turn appliances off for a few seconds to a few minutes in response to power grid overload.
By triggering appliances to turn on and off at different times, this device could help control power oscillations that occur in different parts of the grid. "Grid friendly™ appliances reduce some of the load on the system to balance supply and demand.
