This answer is given in two parts and pertains to the Standard Pre-Bid Letters of Credit and the Standard Post-Bid Letters of Credit separately.

Once your Pre-Bid Letter of Credit for a Company has been found acceptable and once the deadline for submission of the Pre-Bid Letter of Credit has passed, there is neither an opportunity nor a process for changing the Issuing Bank.  The Pre-Bid Letter of Credit will not have expired and the cancellation of the Letter of Credit would require the affirmative action of the Company.

You may change the Issuing Bank for the Standard Post-Bid Letters of Credit as long as you provide notice to the Company for which you have executed a supplier contract. The replacement Letter of Credit is subject to acceptance by the company.  You must use one of the two standard options posted to the Final Materials page of the Fall Block Energy and Capacity section of the procurement website should you choose to change the Issuing Bank for the Standard Post Bid Letter of Credit.
