a controller configured to receive the measurement data from the sensors and to communicate with at least one component adjusting device to adjust a component of the electric power grid, wherein the controller is configured to operate the electric power grid in a modification on state or in a modification-off state and to determine a change in energy characteristics between the modification-on state and the modification-off state using a paired t measurement, wherein the paired t measurement determines an average shift in a mean energy usage, and wherein the modification-on state is a conservation voltage reduction (CVR) “
ON”
state and the modification off state is a CVR “
OFF”
state and wherein the paired t measurement includes a pairing process to determine a CVR factor for the electric power grid;
wherein the at least one component adjusting device is configured to adjust a component of the electric power grid based on the measurement data.
