About the Offshore Wind Farm Partnership

The Long Island – New York City Offshore Wind Project is a public-private partnership being advanced by a collaborative that includes:

•           Con Edison

•           Long Island Power Authority (LIPA)

•           New York Power Authority (NYPA)

The concept for the offshore wind project is consistent with New York State's “45 by 15” program, which establishes the goal for the State to meet 45 percent of its electricity needs through improved energy efficiency and renewable sources by the year 2015.  

A joint feasibility study conducted by Con Edison and LIPA concluded that an interconnection of up to 700 MW of wind power, located at the desired location in the Atlantic Ocean, would be feasible with upgrades to their respective transmission systems.

Advantages of Wind Power

The project was developed as a result of the increase in interest toward reducing the use of fossil fuels for electricity production. For New York City and Long Island, the potential use of offshore wind power appears to be a renewable resource that could provide a significant amount of clean energy to consumers.

Any successful wind-generation project for the New York metropolitan area must be centralized and large enough to be cost-effective. It must interact with the electric grid at a high-voltage transmission level, and provide hundreds of megawatts of power. In addition, it must be close enough to where the electricity is used so that the energy can be harnessed and distributed economically.

A Long Island, New York City area wind project warrants an offshore location due to the sheer size of wind turbines, coupled with the availability of strong, consistent, and unobstructed wind. Wind's relative low-energy density makes it necessary to build large wind turbines in order to generate reasonable amounts of electricity.

An offshore wind facility of this size has distinct advantages over inland options. In contrast to land-based wind facilities in remote regions of the state, ocean-based wind power is stronger, more consistently available, and can be situated closer to Long Island and New York City. Also, land-based wind power availability tends to diminish during the hottest part of a summer day, which is precisely the time that Long Island, New York City and Westchester customers use the most electricity. The higher transmission cost adds to the expense of remote land-based wind power.
