Tariffs & Rates


To determine your customer's electricity costs you first need to know their tariff (also called a rate plan). The tariff is the set of billing rules used by the utility to charge your customer for their electricity usage. In most cases your customer will have a choice of tariffs provided by their utility and Genability can help you determine what tariff best fits their usage.

Genability starts the search process with your customer's zip code and customer type. This will narrow the choice of tariffs dramatically, usually to less than 10 choices. From there you can consider the other factors that would limit your customer's choice of tariff, such as maximum peak demand or if they heat with electricity. If you aren't sure your customers' tariff, Genability provides a most likely tariff based for you. Genability also provides the percentage probability that your customer is on that tariff. This feature enables you to make some assumptions without going back to your customer. Once a tariff is selected, Genability Explorer can apply those specific billing rules to any set of usage data.


Tariffs are comprised of rates, the specific line item charges on your customer's utility bill. Tariff rates define charges for consumption (kWh), demand (kW), power factor, meter charges and any other service provided by the utility.

Genability captures all charges levied by the utility, down to the smallest detail. All rates are stored within the Genability data model unbundled allowing you a window into the smallest building blocks of your customer's bill. When you run a calculation Genability Explorer uses all of the rate-level detail and never uses blended or averaged rates.
