W&S-150: We expect to bid one Project in this upcoming procurement event and another Project in a future procurement event. Does the requirement that the Bidder and Seller must be the same entity when submitting a Proposal for only one Project apply to us?

Yes, the requirement applies to each procurement event separately. If the Bidder is submitting a Proposal for a single Project in this procurement event, the Bidder and the Seller must be the same entity.
