Gas Choice 
Information for Gas Transportation Customers

Our gas transport system provides information about daily usage, nominations and billing information for gas transportation customers.

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

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