Port of Long Beach, Pier J Shore to Ship Power

Location: Long Beach, CA
Owner: Port Of Long Beach
General Contractor: Helix Electric, Inc.
Summary: This project includes four miles of open trenching through an operating Port to distribute Utility power to four new 1200A/15kV substations. The substations transform the Utility power to 6.6kV and provide switching for twenty Shore Power Outlet locations spread across two separate wharfs. In addition, the 6.6kV Shore to Ship power is monitored and metered at each substation through PLC with HMI access. The 6.6kV power is extended from the substations underground and under wharf to feed in parallel two each shore power outlets at each of the twenty locations.
