SSC Tornado Resiliency - Generator Replacement for Test Complex

NASA/SSC has a requirement for the major restoration and replacement of SSC’s Test Complex generators which connect to the 13.8kV high voltage system and provide backup power to the test complex. The base scope of work includes the following: Replace the four (4) existing 1.5MW, 4160V generators at B-4400 with new generators of lesser capacity. Removal of the existing generators is not in scope, as the new generators will be installed in a separate location. Existing 4160VAC transformers will remain in place. New 480V generators will be capable of delivering a maximum of 3.5MW of emergency power to the test complex. Assume a generator configuration of 2x1750kW. Perform load study to verify generator sizing. Provide all necessary equipment including 15kV breaker, 480V step-up transformers transformer, NEMA 3R Low Voltage switchgear/equipment, relays, etc., to connect the new generators to the HV switchyard. Provide generators with day-tank. Connect to the existing B-4400 diesel storage tanks. Provide new piping and transfer pumps to the generators. Provide elevated metal platforms for generator maintenance/access. Provide provisions to connect a spare/portable generator. Connect the new generators to site Emergency Management and Control System (EMCS) and to B-4400 Control room for monitoring. New generators will have the capability to synchronize with the utility. The new generators are to be used as emergency backup only. Replace existing knife-blade switches on Circuits 11 and 21, feeding the underground circuits on the north side of the B-4400 switchyard with new Gang-Operated Air Break (GOAB) switches. Replace sand fuses feeding B-4400 480VAC transformers 400A and 400B with modern fuses. NASA/SSC intends to issue a sole source task order against GSA contract 47PA0425D0027 to acquire the services from Mississippi Power Company under the authority of FAR 6.302-1. The Government does not intend to acquire a commercial product or commercial service using FAR Part 12. Interested organizations may submit their capabilities and qualifications to perform the effort electronically via email to Rachel Clayton at [email protected] not later than 3:00pm CST on August 22, 2025. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether to conduct this acquisition on a competitive basis. A determination by the Government not to compete this acquisition on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the Government. NASA Clause 1852.215-84, Ombudsman, is applicable.
