Gas Transport System (USMS) 
Information for Gas Transportation Customers 
Our gas transport system, also known as Unbundled Services Management System (USMS), provides information about daily usage, nominations, and billing information for gas transportation customers.

Ameren offers transportation service (Rider T) to all non-residential customers. Customers who elect Rider T purchase natural gas supplies from a source other than Ameren. The customer may purchase gas themselves or through a retail gas supplier.

Our online portal puts the information you need at your fingertips.
