The Northwest Seaport Alliance (NWSA), a marine cargo operating partnership of the ports of Seattle and Tacoma, has announced refrigerated electrical upgrades on its Terminal 5.
The purpose of the proposed project is for SSA Terminals (Seattle Terminals) LLC (SSAT) to install the necessary electrical infrastructure to supply power for up 960 new reefer containers.
The project includes pulling new service from the existing T5 primary substation at the south end of the facility through the existing duct bank installed as part of the Terminal 5 Berth Modernization Upgrades project.
New duct bank, power, and communication vaults will be installed, extending the existing 15kV duct banks to provide service to four new refrigerated container substations (substation 5/6 and substation 7/8), which provide power for outtap boxes and refrigerated container receptacles.
Substations and refrigerated container plugs have been pre-procured by the owner. Installation of the substations will be the responsibility of the site contractor and coordination will be required between the substation vendor, owner, engineer, and site contractor.
This project is being partially funded by a USDOT Maritime Administration (MARAD) Port Infrastructure Development Program (PIDP) Grant and will be subject to Buy American Requirements.
According to NWSA, the estimated cost for these upgrades is between US$25 million to US$30 million.
