ESA South Awarded Design-Build NAVO UPS System Replacement at Stennis Space Center

ESA South has been awarded a $10.6 million design-build contract for the Uninterruptible Power Supply (UPS) System Replacement at the Naval Oceanographic Office (NAVOCEANO), located at John C. Stennis Space Center in Mississippi.

NAVOCEANO, headquartered at Stennis, provides vital oceanographic products and services that support the U.S. Navy and Department of Defense. Reliable and continuous power is essential to NAVOCEANO’s mission, as the facility houses critical computing and data infrastructure that supports global naval operations.

Under this contract, ESA South will replace the existing five (5) MGE EPS8000 UPS units with five (5) new 750kVA/750kW UPS parallel modules, as well as install new battery breaker cabinets utilizing the existing battery system and perform 4000A main switchgear modifications. The project scope also includes comprehensive site assessments, platform system design, procurement, installation, and full project management from start to finish.

Because this building is a mission-critical facility operating 24 hours a day, seven days a week, all work will be closely coordinated with the user to avoid any disruption to ongoing operations. ESA South will develop phased work and power outage plans for approval prior to execution, ensuring that all activities align with NAVOCEANO’s operational and security protocols.

The design-build team will also ensure strict adherence to Unified Facilities Criteria (UFC) and all applicable building codes, while following all Stennis Space Center and NCBC Gulfport security requirements. Work will be executed in accordance with federal safety, quality, and environmental standards, with additional precautions taken to protect sensitive equipment and personnel within the facility.

This project reflects ESA South’s continued success in delivering complex, mission-critical design-build projects for federal clients. The firm’s expertise in executing technically demanding work within active, secure environments positions ESA to support NAVOCEANO’s ongoing mission and the Department of Defense’s global readiness objectives.
