    Sec. 19-135. Single billing. It is the intent of the General Assembly that in any service area where customers are able to choose their natural gas supplier, a single billing option shall be offered to customers for both the services provided by the alternative gas supplier and the delivery services provided by the gas utility. A gas utility shall file a tariff pursuant to Article IX of this Act that allows alternative gas suppliers to issue single bills to residential and small commercial customers for both the services provided by the alternative gas supplier and the delivery services provided by the gas utility to customers; provided that if a form of single billing is being offered in a gas utility's service area on the effective date of this amendatory Act of the 92nd General Assembly, that form of single billing shall remain in effect unless and until otherwise ordered by the Commission.
