Tunnel Option - Typical Business Flow

Once all the control table data is set and a customer's service agreement has been activated, here is what typically happens in the course of a month:

• Market prices are received periodically and interfaced into the system.
• The customer's measured data is received periodically and interfaced into the system.
• The data derivation background process runs periodically and creates new "within tunnel" and "outside tunnel" data.
• When billing executes, it bills the "within tunnel" data and "outside tunnel" data according to the rate algorithms.
