South Terminal Upgrades
As a subconsultant, Elcon provided electrical design for the South Terminal upgrade, which included demolition of existing 480V apron and bullrail electrical systems, and the relocation of an existing Maintenance Building, located on the South Terminal.
A new 12.47kV main switchgear was designed, including a new Snohomish County PUD medium voltage electrical service to support the main 12.47kV to 4.16kV crane substation and a future substation for ship-to-shore power for two container vessels. South Terminal’s upgrade supports two 100-Gauge 1.2 MVA container cranes, and provides future ship-to-shore power. The electrical system also includes 12.47kV to 480/277 and 480 to 208/120V transformers to provide bullrail power and to support other miscellaneous loads throughout the South Terminal. The electrical design of this project was completed on time, and within the negotiated budget resulting in an overall successful project.
South Terminal’s lighting options were modeled using AGi32 lighting modeling software. Elcon developed three lighting options and presented a cost/benefit analysis. The scenarios examined energy consumption and utility rebate compensation. Final analysis showed the “all LED” scenario used half of the energy of the “all HPS” scenario, and the LED fixtures were eligible for a utility rebate to cover over 50% of the fixture cost, and an energy savings payback period of 2.7 years.
