The Department of Energy, through Battelle Energy Alliance, LLC, is seeking Expressions of Interest (EOI) from qualified vendors for the TAN Firewater Upgrade Project at the Idaho National Laboratory (INL) in Idaho Falls. The project aims to upgrade and replace critical firewater infrastructure at Test Area North (TAN) to restore system reliability and ensure compliance with safety standards, addressing issues such as corroded piping, fire sprinkler risers, and tank heaters. This initiative is vital for maintaining the operability of the fire suppression system across multiple TAN facilities. Interested vendors must submit their EOIs by July 1, 2026, including company information, relevant capabilities, NAICS codes, and any federal contracting experience, to Chase Egbert at chase.egbert@inl.gov.
