W&S-56: Is it possible that a bidder will have to sign contracts with more than one utility for RECs from a single project?

Yes.  The Procurement Administrator will allocate to each utility the number of RECs that the winning bidder will deliver to that utility, with the same REC price for all utility contracts.  Winning bidders are not able to choose their counterparties to the REC Contract. Please note that for this procurement, the contract terms have largely been harmonized among the utilities.
