If the tariff you have added to your model is a Distribution Tariff, i.e. it covers only the transmission and distribution part of the utility bill charges, then this is how the tariff will appear your HOMER grid model. You will be asked to add electricity provider rates.
You have two options to create a complete tariff involving both generation and T&D charges.
If you find "Option 1" an oversimplification, you can create the generation tariff using the Advanced Tariff Builder (if you have the rates pdf released by the generation utility) and select the "Import Generation Rates".
Choosing either option to add your electricity provider rates will now give you a tariff which will represent the complete tariff for the customer.
