DG-161: If a Bidder chooses not to bid all of the systems that were qualified through its Part 1 Proposal, is the Bidder still required to provide a Letter of Credit for the full amount in the notification from the Procurement Administrator?

No.  The Letter of Credit must be at least in an amount equal to $4 times the number of RECs that the Bidder can win across all systems and the total Forecast Quantity across all delivery years under the applicable supplier contracts. The Letter of Credit does not need to be in an amount sufficient to support all of the RECs from the systems qualified in the Part 1 Proposal, but it must support at least 1 MW worth of RECs.
