Experience

The Poseidon Project is being developed by a consortium consisting of Anbaric, a nationally known transmission developer, and one of the principal developers of Neptune.

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.

The Neptune Project

The Neptune Project is a 65 mile undersea and underground high voltage direct current (HVDC) transmission line that extends under water and underground from Sayreville, New Jersey to Nassau County on Long Island.  Neptune provides up to 660 MW of power to Long Island electricity consumers – enough for 600,000 homes — and supplies more than 20 percent of Long Island’s typical electricity demand. Neptune began construction in June 2005 and was completed in June 2007, on budget and ahead of schedule.

Neptune operates under a long-term agreement with the Long Island Power Authority (LIPA), which selected Neptune RTS to build and operate the project in a competitive solicitation in 2004. In selecting Neptune, LIPA determined that importing power via the Neptune cable was more economical than building new power plants on Long Island. Neptune provides access to one of the most diverse and competitively-priced power markets in the United States, called PJM, which controls electricity flows in all or parts of 13 states and contains more than 160,000 MW of diversified and relatively low-cost power generation.

Hudson

The Hudson Transmission project is a 660 MW electric transmission link between New York City and PJM Interconnection. While its main purpose is to provide a new source of electric power for the New York City customers of the New York Power Authority (“NYPA”), implementation of the Project also includes very significant upgrades and reinforcements to the transmission system in New Jersey.

The Hudson cable is entirely underground and underwater, using high voltage direct current (“HVDC”) technology. The route begins in Ridgefield, New Jersey, the site of the new Hudson converter station, where it interconnects with the PJM system at a PSE&G substation. Construction of the project began in May 2011 and was completed six weeks ahead of schedule in June 2013.

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.
