Electric power transmission through interconnectors using high-voltage direct-current (HVDC) involves usually two converter stations and a transmission line. Generally overhead lines are used, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and joins two separate AC grids at a ...
The Port of Long Beach, administered as the Harbor Department of the City of Long Beach, is a container port in the United States, which adjoins Port of Los Angeles. [3] Acting as a major gateway for US–Asian trade, the port occupies 3,200 acres (13 km 2 ) of land with 25 miles (40 km) of waterfront in the city of Long Beach, California .
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

The ports of Long Beach and Los Angeles together account for approximately 40% of the shipping containers entering the United States. [7] More than three-quarters of the containers leaving Los Angeles were empty in July 2021 whereas about two-thirds of the containers leaving U.S. ports are typically filled with exports.
The vast majority of containers moved by large, ocean-faring container ships are 20-foot (1 TEU) and 40-foot (2 TEU) ISO-standard shipping containers, with 40-foot units outnumbering 20-foot units to such an extent that the actual number of containers moved is between 55%–60% of the number of TEUs counted.
International Transportation Service (ITS) is an American container terminal company that deals with the receipt and shipment of containerized cargo in domestic and foreign trade. [1] It also focuses on marine cargo handling, vessel stevedoring, on-dock rail, and staffing services. [2] ITS was founded and owned by K Line until 2020. [3]

An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. [ 1 ]
