The Navy is conducting a sources-sought market survey to identify potential offerors for recapitalizing and cybersecurity-hardening the 230kV transmission loop and ancillary equipment at Naval Submarine Base Kings Bay, Georgia, with integration into Georgia Power Company’s grid. The anticipated design-build, firm-fixed-price effort includes relocating the high-power loop/crossing tower across the North River, replacing conductors and substation equipment, modernizing protective relays, and integrating encrypted SCADA telemetry compliant with NERC CIP and DoD UFC 4-010-06. The anticipated period of performance is about 900 calendar days from award, and the estimated procurement magnitude is between $100,000,000 and $250,000,000. A sole-source award to the regulated utility provider is anticipated because third-party contractors cannot access Georgia Power’s proprietary SCADA switching software and its utility-specific integration capabilities are considered essential. Interested parties—including large, small, 8(a), HUBZone, SDVOSB, VOSB, and WOSB businesses—with relevant high-voltage, security-cleared, cybersecurity, and utility-interconnection experience may respond via the attached questionnaire; no solicitation, specifications, or drawings are currently available.
