AI Contract Overview

The Department of the Navy, through Navfac Mid-Atlantic, is seeking to modernize the SA substation to improve reliability and system redundancy. The project involves replacing a 54 year old substation transformer with a new 20MVA, 34.5kV to 11.5kV unit, along with the installation of new dead-front, metal-clad, draw-out switchgear featuring 15 kV vacuum circuit breakers and a new station grounding resistor. The scope of work also includes the salvage, demolition, and removal of all existing outdated equipment. A critical component of the upgrade is the installation of a new 35kV SF6 4-way switch. This addition provides the SA substation with access to an alternative Navy South circuit, significantly reducing potential downtime. While the current configuration relies solely on circuit NS15 and requires several hours to reconfigure during a failure, the new switch will allow power to be restored in less than one hour.

Full Description

09/12/2023 08:04:24 (PST) : This project will replace the existing SA substation with a modernized equipment and designed for redundancy. The project will replace the 54 year old, unreliable substation transformer with a new 20MVA, 34.5kV – 11.5kV Substation transformer. The existing outgoing metal-clad switchgear will be replaced with dead-front, metal-clad, draw-out, switchgear assembly of vertical sections, each with 15 kV vacuum circuit breakers. The station grounding resistor will also be replaced with a new one. The project includes the installation of a new 35kV (SF6) 4-way switch that will add redundancy to SA Substation. Currently, SA is feed from the Navy South Switching Station circuit 15 (NS15). If this circuit goes down it will take several hours to reconfigure the distribution system to pick SA’s load. But with the new switch, SA Substation will have access to another Navy South circuit. If the primary feeder (NS15) goes down, power to SA Substation can be restored in less than an hour due to the addition of this 4-way switch. The project will include the salvage, demolition and removal of existing equipment.
