Each Bidder in the New Solar RFP will be required to provide bid assurance collateral in the form of cash or a letter of credit separately to each of the three Companies (Ameren Illinois Company (“AIC”), Commonwealth Edison Company (“ComEd”), and MidAmerican Energy Company (“MEC”)) for all the Projects for which the Bidder is presenting a Proposal. The required amounts are as follows:

• $4,000/MW for AIC up to a maximum of $850,000;
• $10,000/MW for ComEd up to a maximum of $2,100,000; and
• $1,000/MW for MEC up to a maximum of $250,000.

For purposes of determining the amount of bid assurance collateral, the size of the Project will be rounded up to the nearest megawatt. In your example, for a Project that is 1 MWac, the required bid assurance collateral will be $4,000 for AIC, $10,000 for ComEd, and $1,000 for MEC.
