Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the LBNL RFP MG-02122026.

• Obsolete Parts Support: For assemblies, Delta Power Supplies have a 12-14 week lead time for first articles and an additional 20 weeks for production units. While Delta may supply sooner, they commit to 32-34 weeks, which does not meet the November 10, 2026 delivery requirement. Delta's schedule supports the Estimated Term of 51 weeks (ARO) as per RFP Section 1.1. LBNL requires a parts kit verification by the vendor, detailing discrepancies and an alternate parts list for review and approval. If an alternate part is unavailable, LBNL will provide guidance.
• Electrical Device Certification: The Electrical Device Certification Requirement, as stated in the "Subcontract No. TBD" document, Page 2, pertains to each of the 5 assembled LBNL Units (e.g., BPC-2CH-S-18V-24A) as first article and production items.

These clarifications address specific vendor inquiries regarding lead times, delivery, and certification requirements, potentially impacting how bidders prepare their proposals and understand the scope of work.
