# Tariffs ## OpenEI Tariffs Consumption costs and demand rates are generated though the use of OpenEI Utility rates. You can select the desired tariff in this menu by creating a tariff and selecting OpenEI as the tariff provider.

## Ecosuite EI Tariffs If you do not wish to use a rate provider like OpenEI we offer a way to manually create tariffs through the use of an EcosuiteEI Tariff. This Tariff uses the same structure as an OpenEI tariff while allowing you to set custom values. ### Hourly Rates/Structures For each month you can set rates that change on an hourly basis. Each of the rates can be a rate structure or a flat rate as shown below:

#### Flat Rate:

A Flat Rate will simply charge an amount of currency per kWh. To use this method, simply enter a rate into each of the desired hour slots. #### Rate Structure

A rate structure will charge different rates depending how much power is used. For example: * The first 20kWh will be charged at 20c per kWh * The next 100kWh will be charged at 15c per kWh For the final tier you can leave the max unset in order to change the remaining kWh at that rate. In order to use this rate structure at a given hour, you can enter its index into the hour slot
