The Siemens Subsea Power Grid is a complete medium-voltage power supply and distribution system installed on the seabed that incorporates proven high-quality industrial components including subsea transformer, subsea switchgear, and subsea variable speed drives, as well as a comprehensive power control and communication system. It aims to be the first at water depths down to 3,000 meters at long step-outs from the host, and will be one of the key enablers for large-scale subsea processing.
