W&S-207: Are winning bidders required to provide the Collateral Requirement under the REC Contract as a condition of the return of the bid assurance collateral?

Yes, it is one of the conditions. If the Project is selected and is approved by the Commission, the bid assurance collateral can only be returned once all REC Contracts are executed, any Collateral Requirement under each REC Contract is posted, and the Supplier Fees are paid.  Supplier fees are due seven business days after the Commission decision.
