What is "Supply Rate" when inputting customer energy use?

A tariff may have a "Supply Rate" which is the cost per kWh of energy for your individual customer.

In deregulated markets like Texas, customers can buy their energy from one of many providers, but their local utility delivers the energy. So they pay $0.XX / kWh as a supply rate. In SolarNexus, we have the utility's delivery charges, but since each customer can pay a different energy supply rate, that is input by you. You should be able to easily find that rate from the customer's bills. If you don't input a supply rate, SolarNexus will assume one for you.

NOTE for California IOU's: Although California's utility market is not deregulated to the extent that supply rates are common, they are possible. The CA PUC has something called the Direct Access program, where the customer receives its supply from a third party retailer rather than the utility.

If you select a tariff where Supply Rate appears as a field, then that tariff is probably under the program.

Also note that if a tariff with a supply rate is identified as a TOU rate, you can assume that the third party supply contract does not have TOU pricing. Very few third party supply contracts price power differently by time of day unless they are linking it to ISO pricing. So even though this is a TOU tariff, it's highly unlikely that the customer has a supply price that varies by TOU. So if the customer is in fact on this tariff, you should find out what their contracted energy rate per kWh is, and input that.
