Electrical devices are considered grid friendly if they operate in a manner that supports electrical grid reliability through demand response. Basic grid-friendly devices may incorporate features that work to offset short-term undesirable changes in line frequency or voltage; more sophisticated devices may alter their operating profile based on the current market price for electricity, reducing load when prices are at a peak. Grid-friendly devices can include major appliances found in homes, commercial building systems such as HVAC, and many industrial systems.

Participants included local utilities, residential and commercial customers, industrial loads belonging to municipalities, and a number of vendors and researchers. The grid-friendly technology demonstration showed that common residential appliances did automatically detect grid problems expressed as frequency deviations and reduced energy consumption at critical moments. The Olympic Peninsula demonstration showed that residential, commercial, and industrial loads did adjust their consumption patterns based on price signals emanating from a distribution-level market operated as a double auction. Both of these projects showed how grid-friendly technologies can and do reduce pressure on the electric grid during time of peak demand. ==See also== Dynamic demand Energy demand management GridLAB-D
