Attachment 3 - Proposed Payment and Milestone Schedule.xlsx

The file is an Attachment 3 - Proposed Payment and Milestone Schedule for Solicitation SUB-2025-10263, detailing a comprehensive project milestone schedule for an equipment enclosure for a PEM Megawatt-Scale Low Temperature Electrolyzer at the National Renewable Energy Laboratory (NREL). The document outlines seven key project milestones, including structural design and engineering drawings (at 90% and 100% completion), equipment enclosure manufacturing, photographic/video documentation, delivery to NREL, installation and commissioning support, and final "As Built" drawings.

The payment schedule indicates zero dollar values ($0.00) for each milestone, suggesting this may be a cost-reimbursement contract or that pricing details are contained in a separate document. The project is sponsored by the Department of Energy Office of Science and involves creating a 24 x 50 feet enclosure with 12-foot ceilings designed to house and climate control electrolyzer stacks and balance of plant equipment. The solicitation focuses on design, manufacturing, and delivery of a specialized research facility infrastructure component for advanced hydrogen electrolysis technology.
