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.

• 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
  Amboy.
• 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.
