Building a tariff is useful in cases that you are unable to find a tariff under the Choose Tariff from Database option. HOMER Grid lets you quickly build a simple tariff using this option. However, if you realize that this option is not suitable for your complex tariff, then you can build a complex tariff using the advanced tariff builder in the Library Editor.
A tariff created using this Simple Tariff option:
•Can include one energy charge, one demand charge and one fixed charge
•Can allow for net metering
•Cannot cover tiered rates, time of use rates and other complex rate structures.
To create a simple tariff, follow the below steps.
If you realize that your tariff is a lot more complex and cannot be built with this option, then select the User Library tab and and choose the "Launch HOMER Tariff Builder Application" button. You may also access the tariff builder from the found on the upper right hand corner of the main window.
