Naval Nuclear Laboratory (NNL), operated by Fluor Marine Propulsion LLC (FMP) for the Department of Energy, is accepting proposals to develop a lithium-ion battery as a backup energy storage system capable of providing 2.4 MW*hrs of usable energy throughout life. For the design of the battery system to be considered successful, it must demonstrate balance of the objectives of continuity of power, not exceeding design limits, and integrating a sufficiently robust safety posture such that the risk to the host asset is reduced to an acceptably low level. The battery system shall have the capability and reliability to maintain operations both during and after a “credible casualty” of the battery system. Credible casualties and other critical details of the system are outlined in the requirements table below. The goal of this work scope is to develop a battery system that meets the energy/power demands of the system and fits within the specified volume while maintaining a sufficient safety posture. This RFP is for development of a prototype only, and additional unit purchase are not guaranteed at the present time.  
The requested submission deadline for proposals to this RFP is April 7, 2025. Funding decision will be made by October 2025. As part of this RFP solicitation, FMP will hold an information session to solicit any questions and to provide feedback about the RFP as needed.
