Economic Benefits

The principal challenges facing the rapid expansion of renewable energy at a scale that makes a carbon reduction impact is the land area required for projects that can achieve economies of scale, the distances that this power must travel to reach markets, and the grid congestion that limits the amount of renewable energy that can reach these markets.


These challenges can be addressed by creating a regional energy market to stimulate trade, drive down the cost of renewable energy, and increasing access to markets. New transmission lines, like Poseidon, are necessary to move renewable energy from where it is affordable to where it is needed and to reduce grid congestion to ease access to markets. Importing and exporting renewable energy across northeastern North America creates a winning combination: opening markets, increasing competition, and reducing costs.


Poseidon will be a second link between Long Island and the PJM market. PJM has a substantial and growing ability to supply significant amounts of renewable energy and capacity at attractive prices. The world’s largest wholesale competitive market spanning 13 states, PJM has over 10,000 MWs of installed renewable generation capacity with an additional 15,000 megawatts in various stages of development, including large-scale wind, solar, and hydro. Of the resources either planned or under construction, over 11,000 MWs consists of wind. At this scale, the PJM market offers a unique opportunity to supply Long Island with affordable, renewable energy with no increased air or water emissions, no impact on the aquifer or the preservation of open space, and no alteration of viewsheds.

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.






Notice of Open Solicitation

Poseidon Transmission 1, LLC (the “Company”), seeks generation suppliers wishing to offer energy, renewable energy credits, and/or capacity to the New York Power Authority (“NYPA”) via the Poseidon Transmission Project, a 79 mile high voltage, direct current transmission link between PJM and Zone K in the NYISO.

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.
