Newly available HVDC conductor cable technology enable the delivery of large quantities of affordable electricity across long distances to urban load centers with little line loss. These extruded cross link polyethylene (XLPE) cables allow for simpler and less expensive splicing, easier handling in the field, a small installation footprint and high-power transfer capability. This cable technology enables the SOO Green HVDC Link project to be unaffected by severe weather incidents.
SOO Green HVDC Link will use innovative converter stations known as self-commutated Voltage Sourced Converters (VSC) that provide important grid support functions and power transfer capabilities not previously available. VSC technology boosts reliability by providing highly responsive utility-scale reactive power, dynamic voltage support, black start and other grid services. With the largest VSCs ever installed in the United States, the 2,000-megawatt SOO Green HVDC Link will deliver functionality to the power grid similar to that of a large power plant but without any adverse environmental or community impacts.
