Jersey Link Project Technology

One Cable Corridor, Three Cable Systems

This state-of-the-art transmission solution offers one of the most efficient ways to transport generated power from offshore wind to onshore load stations.

  • All cables share the same corridor for nearly their full length — onshore and landing point — minimizing impacts.
  • Enables connection of the same amount of offshore wind energy as three separate transmission systems, but with the environmental impact of just one system.
  • Three cable systems can be designed, permitted, and constructed at the same time, ensuring a highly reliable and quickly deployed transmission system with minimal community impacts.
Underground and Subsea Cables Alongside Existing Infrastructure
  • The route will utilize underwater and underground transmission to minimize the impact to both local communities and the environment.
  • Cables will be underground and subsea for their entire length, both onshore and landing point.
  • Cables will make landfall beneath a former industrial pier in South Amboy.
  • Cables will utilize existing rights of way to the extent practicable when connecting to the Deans substation.

Proven, Superior Design: Benefits of HVDC Transmission

  • State-of-the-art high-voltage direct-current (HVDC) transmission has superior economics and capabilities for long‐distance and submarine applications required to deliver offshore wind. 
  • Jersey Link’s well-proven, scalable HVDC design uses a DC system rated for 1,200 MW. Building up to three of these HVDC circuits will enable a total of 3,600 MW to be connected to PJM’s bulk power system. 
  • HVDC design avoids perceived public health concerns from electromagnetic fields that are common with HVAC transmission lines.
  • HVDC design has higher efficiency and lower line losses over larger distances, resulting in lower costs over the life-cycle of the transmission line.
