The new partnership will be a key milestone in building a US Clean Energy Grid, and bring in new HVDC transmission cable manufacturing capacity and jobs to the United States.

SOO Green HVDC Link has announced the selection of Prysmian Group – the worldwide leader in the energy and telecom cable system industry – as its preferred supplier of high-voltage direct current cable systems for this first-of-its-kind transmission project to be installed underground along existing railroad rights of way. The 2,100-megawatt interregional project, considered the first link in a national clean energy grid, will connect two of the largest energy markets in the US. By linking the Midwest Independent System Operator (MISO) serving the central US, to the eastern PJM Interconnection, SOO Green will deliver abundant, low-cost renewable energy to population centers from Chicago to the mid-Atlantic region.

With a value of approximately USD 900 million, Prysmian Group will provide state-of-the-art ±525 kV class HVDC cable to reliably and efficiently transmit enough renewable energy to power more than 1.2 million homes. Award is subject to the finalization of contract. The construction part of the project, currently under finalization, will be performed by Jingoli Power and will be added to the overall contract value. Prysmian will be responsible for the full turnkey contract. The 350-mile-long project will require 700 miles of paired ±525 kV cross-linked polyethylene class cables installed underground primarily along existing railroad rights-of-way connecting SOO Green’s converter station in northern Iowa to its Illinois converter station just west of Chicago. Cable production for the project is expected to start in 2023.

With sales of over EUR 10 billion, 28,000 employees in over 50 countries, and 104 plants, following the integration of US cable manufacturer General Cable, Prysmian Group relies on a wide US presence with 23 plants, around USD 3 billion in sales, and around 6,000 employees. Cables will be manufactured in Prysmian’s Abbeville, South Carolina facility, which will be upgraded to supply the high voltage cable needed to help achieve President Biden’s goal of a zero-carbon power grid by 2035.
