STP-4: If I have a pre-existing contract with one of the Companies, can this contract be used for purposes of the procurement events under the IPA’s Standard Products RFP?

The “Companies” are Ameren Illinois Company d/b/a Ameren Illinois (“AIC”), Commonwealth Edison Company (“ComEd”), and MidAmerican Energy Company (“MidAmerican”).  There is, for each Company, a standard supplier contract that must be accepted and used by all Bidders in the Company’s procurement event under the Standard Products RFP.  Prior agreements that a Bidder may have entered into with a Company cannot be used for purposes of the IPA procurements events. Please review the applicable supplier contracts for the Standard Products RFP that are posted to the “Standard Products” page of the IPA web site ( as they become available.
