1. A voltage control and energy conservation system measurement technique using paired t distributions to calculate without a use of weather normalization a change in energy use or improvement in conservation performance in energy reduction on a system, comprising:
an electrical energy delivery system with a substation configured as an electrical supply system supplying power through an electrical distribution system to an electrical usage system for use by electrical usage devices at a plurality of user locations; a plurality of meters, wherein at least one a meter is located at the substation and at least one meter is located at the at least one of the plurality of user locations, and at least one of the plurality of meters is configured to generate smart meter data based on a measured component of electrical power received by the smart meter; and a voltage controller configured to generate an energy delivery parameter based on the smart meter data, wherein the substation is further configured to adjust a voltage set point value of the electrical power supplied to the plurality of user locations based on the energy delivery parameter, and wherein the voltage and energy are measured on an interval basis using an energy validation process and a change in energy characteristics, the energy characteristics including a conservation voltage reduction (CVR) factor, and an energy savings between the voltage at the CVR “ON” set point and the CVR “OFF” set point are measured using a paired t measurement using an optimized pairing process to determine the CVR factor and the energy usage improvement for the electrical energy delivery system, and wherein the paired t measurement determines an average shift in a mean energy usage, wherein the pairing process comprises an additional process that breaks the paired t process into measurements of CVR factor and conservation energy savings by season and uses linear regression constants to determine blocks of hours where consistent loads exist and paired t comparisons are configured to be calculated within predetermined limits.
