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 offshore,
    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.
  • Small cables are approximately 13cm or 5 inches in diameter.
  • Three cable systems can be designed, permitted and constructed at the same time, ensuring a
    highly reliable, quickly deployed transmission system with minimal community impacts.
100% Underground and Subsea Cables Alongside Existing Infrastructure
  • The entire 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
    offshore and onshore.
  • Offshore cable route follows existing infrastructure such as shipping
    lanes and existing submarine pipelines and cables.
  • Cables will make landfall beneath a former industrial pier in South
  • Cables will utilize existing Rights-of-Ways on the proposed route.

Proven, Superior Design

  • ‘Originally developed in the UK, the well-proven, scalable HVDC design uses a ±320 kV 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 from 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.
