Prysmian SOO Green HVDC Cable Deal Connects Major U.S. Power Markets
Prysmian Group secured a turn-key contract worth about €900 million to supply roughly 700 miles of ±525 kV XLPE HVDC cable for the SOO Green HVDC Link project. This Prysmian SOO Green HVDC Cable Deal will connect two of the largest U.S. energy markets through a new underground transmission corridor.
Prysmian SOO Green HVDC Cable Deal Backs First-of-Its-Kind Link
SOO Green HVDC Link, LLC selected Prysmian as its preferred high-voltage DC cable supplier for this first-of-its-kind project. The 2,100 MW interregional link will run underground along existing railroad rights-of-way, which reduces visual impact and simplifies permitting.
The SOO Green line will connect the MISO (Midcontinent Independent System Operator) region in the central U.S. with the PJM Interconnection in the East. Together, these markets will deliver enough clean power to serve more than 1.2 million homes. For more details, see www.soogreenrr.com.
Ownership, Development, and Construction Partners
Investment funds managed by Copenhagen Infrastructure Partners, Siemens Energy, and Jingoli Power own SOO Green. Meanwhile, Direct Connect Development Company, LLC, based in Minneapolis, leads project development and coordination.
The award to Prysmian still depends on final contract approvals. However, Jingoli Power will perform the construction scope, which will be added to the project’s overall contract value once finalized.
Route, Converter Stations, and Cable Manufacturing
The underground HVDC cables will primarily follow railroad corridors between northern Iowa and northern Illinois, just west of Chicago. They will link SOO Green’s converter station in Iowa to a matching converter station in Illinois, enabling efficient long-distance power transfers between regions.
Prysmian expects cable production to begin in 2023. The company will manufacture the cable at its Abbeville, South Carolina facility, which it is upgrading to support large-scale U.S. transmission projects.
Supporting the U.S. Zero-Carbon Grid Goal
This project supports President Biden’s goal of a zero-carbon power grid by 2035 because it helps move low-carbon and renewable energy from high-resource areas to major demand centers.
Prysmian Group CEO Valerio Battista noted that, after flagship wins such as the Vineyard offshore wind farm contract and the Washington, D.C. transmission upgrade, this opportunity further strengthens Prysmian’s role as a partner of choice in the U.S. interconnector market.
