From the article:
The project uses High Voltage Direct Current (HVDC) technology to convert electricity from alternating current to direct current power, and then back to AC power at a converter station in Ridgefield, New Jersey.
The principal contractors on the project were German engineering firm Siemens AG, which supplied the HVDC equipment, and Italian cable company Prysmian SpA, which supplied and installed the cable.
