System Planning Flexibility

Poseidon’s cost savings provide system planners with unrivaled flexibility to accomplish a range of strategic goals, including investing in renewables, repowering older units, and more – all while ensuring system reliability.

740 MW of Long Island generation will turn 60 years old by 2023, underscoring the need to take measures now to prevent future problems. With Poseidon, decision makers gain a flexible asset that can be used to import additional capacity incrementally, as needed, to repower older units in a cost effective manner.

Today, Long Island obtains 325 GWh of renewable energy via its transmission connections, such as Neptune and Cross Sound Cable. As decision makers seek to expand the role of renewable resources in Long Island’s energy mix, Poseidon provides access to at-scale affordable renewable generation in PJM.

The cable’s expected lifespan of 50-75 years ensures that grid planners can utilize Poseidon to achieve their energy goals long into the future.

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.
