Supply voltage is the voltage of the feeder line from which a service point is supplied. Delivery voltage is the voltage at the point of connection between the utility’s facilities and the customer’s facilities. Meter voltage is the voltage at the point where the meter is connected. <br><br>
If the supply voltage and the delivery voltage are different, then the customer’s account is billed a transformation charge. This charge is described in the applicable Delivery Services tariffs. <br><br>
If the meter voltage and delivery voltage are different, then the service point’s metered usage is adjusted before applying any applicable delivery or power supply rates. The most common reason for the meter voltage and the delivery voltage being different is that the meter is installed at a location of convenience. <br><br>
For example, assume that a customer’s service point is served at 12kV (primary voltage). However, the utility owned transformer that takes the voltage from 34kv (high voltage) to 12kv (primary voltage) is located inside the customer's security area. For the convenience of reading the meter, the meter may be located on the high side of the transformer that is outside of the security area. In this scenario, the service point would have a delivery voltage classified as primary voltage and a meter voltage classified as high voltage. Since delivery services rates are dependent on a service point’s delivery voltage, the usage readings taken from the meter (which is at high voltage in this scenario) must be adjusted before calculating billing charges.
