How do I view my Billing History and Utility usage?

Once logged into your account, on the main Account page, their are buttons for "Billing History" and "Account Usage".

Billing history shows all activity, payments and adjustments to the account since the utilities account was created. You can go in and see all prior usage/charges broken down by service.

 

Usage Graph 
The Usage graph is an overview of your usage over a period of time. Below the graph is the actual number usage for the particular date listed. These two features allow you to compare your usage both by the actual number billed and a visual image to help understand the breakdown.
