In Part 2, students will be introduced to the primary data exchange processes used between retail suppliers and the utilities. In the Billing and Payments unit, students will first be introduced to some vital billing-related definitions. Next, the course will introduce students to general billing and payment transactions and processes. 

There are five primary billing options used in the retail energy markets in the United States. The student will also learn that the billing option selected will determine which entity is responsible for the following activities:

*Who should calculate the supplier charges?
*Who should calculate the utility charges?
*Who should prepare the charges, apply taxes, and send the bill to the customer? 
*And last, who is responsible for processing customer payments?

This course ends with a short review followed by a quiz.
