The FAA is conducting a market survey to assess vendor capabilities for a follow-on contract to supply, replace, and repair Commercial-off-the-Shelf battery systems for backup power at FAA National Airspace System facilities across the United States and its territories. The anticipated contract is a five-year Indefinite Delivery/Indefinite Quantity (IDIQ) with a one-year base period and four one-year options, though the period of performance may change. This market survey will help determine whether competition can be set aside for small businesses, and it is not a solicitation or commitment to issue one. Interested vendors are asked to submit capability statements and company information; the FAA will not reimburse response costs.
