Environmental Benefits

The greatest single challenge in the development of renewable energy remains its cost. The second greatest is the land area required for renewables in large megawatt tranches, where economies of scale can begin to drive down costs. The issues have special traction for ratepayers in Long Island, who already pay some of the highest electricity prices in the country, and who live in an area of unique natural beauty and dense residential and business development, where land prices are already high and the preservation of open space is a widely held goal.

In such a setting, importing renewable energy from regions where land is more affordable and where economies of scale can drive the cost of renewables down, offers an ideal complement to renewables provided by local, Nassau or Suffolk sources. Such highly affordable, renewable power can help Long Island meet its renewable and carbon goals, maintain affordability, enhance reliability, improve local air quality, and preserve Long Island’s natural beauty as well as its environment, aquifer and open spaces.

Poseidon connects Long Island to the PJM market, the world’s largest wholesale electricity 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 megawatts of installed renewable generation capacity with an additional 15,000 megawatts in active planning. This includes large-scale wind, solar, and hydro. Of the resources either planned or under construction, over 11,000 megawatts is wind alone. At this scale, the PJM market offers an unique opportunity to supply Long Island with affordable, renewable energy – fulfilling environmental objectives without adverse ratepayer impacts.



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.
