The Department of Energy's National Energy Technology Laboratory (NETL) intends to negotiate a sole source contract with LECO Corporation for the renewal of the Platinum Maintenance Plan for the LECO CHNS, covering the period from March 30, 2025, to March 29, 2026. This maintenance plan is critical for ensuring the continued calibration and operability of the LECO CHNS equipment, which is essential for consistent results within the NETL's operational environment. LECO Corporation is uniquely qualified to provide the necessary installation, adjustment, and training services, as they are the sole manufacturer of the equipment and no alternative sources have been identified. Interested parties who believe they can meet these requirements must submit written evidence of their capability to Anissa Beasinger at anissa.beasinger@netl.doe.gov by 3:00 PM EST on February 17, 2025.
