Poseidon Transmission has been developing this Project for three years. Owing to the overwhelming success of the Neptune RTS line, the developers believe there is strong support for a second intertie between PJM and Long Island. With net positive environmental impacts, great electrical benefits, substantial economic development impacts, a small geographic footprint, and public support, the members of the development team respectfully submit that development of the Poseidon line would be a unique and compelling addition to New York State’s energy infrastructure. Poseidon helps resolve the downstate reliability issues triggered by retirement of Indian Point while providing extraordinary energy, ratepayer, economic development, and environmental benefits to Long Island.

Project Overview

The 82-mile Poseidon line begins in South Brunswick, New Jersey and interconnects in Long Island at the Ruland Road substation in Melville. This high-voltage direct current line will be buried underground or underwater over its entire route –  leaving no residual aesthetic impact on the surrounding environment. Functioning like a long extension cord, the project will help deliver affordable, reliable, and clean energy to the heart of Long Island’s transmission and distribution network.






Economic Benefits

Poseidon’s construction will include the creation of new $100+ million converter stations in Melville and South Brunswick, assets that will generate new tax revenue for local New Jersey and Long Island communities without any additional burden on government services. By providing Long Island with 500 MW of low-cost power from PJM for 50-75 years, Poseidon will deliver affordable and reliable power for generations to come. 

Environmental Benefits

Poseidon produces zero air or water emissions in New Jersey and Long Island, helping to safeguard local air quality and aquifers. Additionally, Poseidon provides Long Island decision makers a cost effective strategy to secure up to 500 MW of renewable power.
