The first request for bid is titled: NREL MMW RO-DI System Specs (Request A). The second request is titled: NREL MMW RO-DI Container Specs (Request B). Offerors can respond to Request A and provide just a RO-DI water system, or they can respond to Request A and B and provide a RO-DI water system inside of a container. To be considered for Request B, offerors must submit a quote for Request A. Bids submitted only for Request B will not be considered. NREL reserves the right to only select a quote submitted for Request A, regardless of whether an associated Request B is submitted. If NREL selects a quote for Request A from an offeror who did not provide a quote for Request B, the containerization process will be handled separately.
