The Neptune Cable is a 500kV and 660 MW [1] high-voltage direct current submarine power cable between Sayreville, New Jersey and New Cassel, New York, on Long Island. [2] It carries 22 percent of Long Island's electricity. [3] It was developed by Anbaric Development Partners.

The cable is managed by Fairfield, Connecticut-based PowerBridge, LLC. [1]

History

The power plant was developed as part of a 2003 request for proposal from the Long Island Power Authority for new generating plants on Long Island [4] that was a response to the Northeast blackout of 2003 and delays by Connecticut in activating the Cross Sound Cable, [5] and due to continued high peak demand over multiple years. [6] [7] This solicitation also resulted in construction of the Caithness Long Island Energy Center; Bethpage Energy Center; and Pinelawn Power Plant in West Babylon, New York. [7]

The cable was constructed following the Long Island Power Authority's determination that importing electricity would make more sense economically than constructing new power generating stations on Long Island.[ citation needed ]

<span class="mw-page-title-main">Electric power transmission</span> Bulk movement of electrical energy

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid.

Glenwood Generating Station is a power station in Glenwood Landing, New York owned by National Grid USA. It is mainly known for being the former site of an architecturally significant 1920s brick power station. That building and an adjacent 1950s station were demolished over the course of 2013 to 2015, due to their obsolescence as well as the excessive cost of safely retaining the building given its poor condition. Four smaller gas turbine peaking generators remain in operation, as does the Y-50 Cable connection across Long Island Sound.

It began operation in 2009 as the first major baseload plant to be built on Long Island in over 30 years, and by 2020 produced the second most net energy generated among power plants on Long Island. A proposal to construct a new unit tripling the capacity of the facility received initial approvals in 2013, but did not proceed and was shelved in 2018.

Caithness Energy, LLC is an independent power producer in the United States. Some of its planned, current, and former facilities include:

Bethpage Energy Center is a power station in Bethpage, New York, United States, consisting of two combined cycle plants opened in 1989 and 2005, and one gas turbine peaking plant opened in 2002. The original plant was commissioned by Grumman Aerospace for its Bethpage complex because it was deemed more cost-effective than purchasing power from electric utilities. It was acquired by Calpine in 1998, which expanded the facility with two more plants.
