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 78-mile Poseidon line begins in South Brunswick, New Jersey and connects to 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 impact on the surrounding environment. The project will help deliver affordable renewable energy to the heart of Long Island’s transmission and distribution network.

Environmental Benefits

The greatest single challenge in the development of renewable energy remains its cost. Poseidon provides Long Island with renewable energy at an affordable price. The project produces zero air or water emissions in New Jersey and Long Island, helping to safeguard local air quality and aquifers.
