Dyess_AFB_Electrical_Study-Volume1 (Final Report)_Redacted.pdf

This is a redacted final report of an electrical study conducted for Dyess Air Force Base. The document provides comprehensive analysis of the electrical infrastructure at the base, with specific focus on Substation Alpha and its associated feeder protection systems. The study examines the existing electrical systems, identifies deficiencies, and supports the technical requirements outlined in the related solicitation for replacing the Substation Alpha Feeder Protection Relays at Building 11912.

The electrical study serves as the technical foundation for the solicitation FA466126R0010, which requires contractors to install two new GE 850 Feeder Protection Relays to replace existing GE 760 relays. The study contains detailed information about the current electrical configuration, system parameters, and performance data necessary for contractors to understand the scope of work, including programming requirements to match existing relay settings, installation standards compliance with NEC/NETA, and testing procedures with full base load. As an attachment to Amendment 0002 of the solicitation, this redacted report provides contractors with essential technical reference material to develop accurate proposals for this Department of the Air Force Global Strike Command requirement, with proposals due September 18, 2026 at 1200 CST.
